Prof. Seyed Mohammadamin Emami

Isfahan University of Art, Iran

Host at the University of Siegen: Dr. Reinhard Trettin, Institute of Building and Materials Chemistry

Current professional background:

I am an associate professor in Mineralogy, Crystallography, and Archaeometallurgy at the Isfahan University of Art in Iran.

Field of research:
  • My main field of research is archaeometry, which combines the study of archaeology with other scientific disciplines, such as material science. This combination is fantastic because it enables you to combine scientific analysis with sociological knowledge to discover more about how people lived in the past. How they produced materials, how they lived etc.
Purpose of your last research visit:

I have been coming to Siegen to study, work and to cooperate for the past 14 years, during these research visits, we have been researching ceramics. We have been focused on 3 particular aspects, raw material usage, manufacturing process and decoration of the ceramics. At first glance this can seem rather simple, but it requires a lot of care to correctly interpret the scientific research and the material characteristics, because often you will only have a small piece of ceramic from which to draw your conclusions. Through careful consideration we can discover many insights into the past, such as the manufacturing process, the kiln process, and how ceramic production developed over time.

We have been investigating samples from the Middle East, from Iran and Iraq. It was fascinating to find out more about the relationship between different civilisations according to the material developments. While there are currently national borders between Iran and Iraq, thousands of years ago there were nations which cut across those borders, such as Mesopotamia & Babylonia, in our research we mainly focussed on Mesopotamian ceramics. More recently we have had some samples from the Roman theatre in Mainz, which is another exciting direction in which we can take our research.

Relation to the University of Siegen and/or to the local host:

When I first came to Germany I studied Mineralogy at Mainz University in 1998. Afterwards I worked in the Max Planck institute as scientific researcher , it was there that I first worked with Prof. Rheinhard Trettin. When Prof. Trettin decided to come to Siegen, I followed him because I wanted to write my PhD under him in the field of Archeaometry. Since finishing my PhD I have been returning to Siegen on a regular basis to continue my research.

Future projects / Activities:

Of course nobody can say with 100% certainty what will happen in future. I intend on coming back to Siegen once again, however Prof. Trettin will retire soon, so that might make it difficult. I am very grateful for all of the kindness and help given to me by him and all of my colleagues here.

Impressions of Siegen:

The University Siegen has fantastic atmosphere of collaboration, we worked together with scientists from many different disciplines during our research, and we could always have interesting discussion with our colleagues, which would sometimes lead to new and interesting areas. The University is also able to provide all of the equipment needed for our scientific analysis. While the city of Siegen does not have so many exciting things to see compared with larger cities, it is noticeably improving very time I come back, and I hope to come back again soon.

Prof. Page Laws

Norfolk State University, USA

Host at the University of Siegen: Prof. Daniel Stein North American Literary and Cultural Studies

Current professional background:

I serve as Professor of English and Dean of the R. C. Nusbaum Honors College at Norfolk State University in Norfolk, Virginia. I have worked at NSU for 31 years. NSU is a Historically Black University that was founded in 1935, in the midst of the Great Depression, to offer Black students in Tidewater, VA (our region’s name at that time) a chance at higher education.

Field of research:
  • My Ph.D. is in Comparative Literature (Yale 1979), with emphases in French/Francophone, German and English/Anglophone literature. I am particularly interested in European and African views of America, and much of my work has focused on modern and post-modern fiction, drama and film. I do Cultural Studies, often with a transnational emphasis.
Purpose of your last research visit:

My most recent visit to Uni Siegen was for a Symposium entitled “Migration and Immigration in Europe and the Americas.” I was accompanied by five NSU Honors faculty colleagues who presented their work at the symposium and enjoyed hearing papers by Siegen professors. Dr. Daniel Stein was the co-organizer of the Symposium. My NSU Honors faculty colleague Dr. Aprilfaye Manalang also visited Cologne and Siegen this past summer to continue her research on the religious views of millennial immigrants to Germany.

Relation to the University of Siegen and/or to the local host:

We have a long-standing relationship begun almost a decade ago by Dr. Cathy Waegner, now retired from the Anglistik/Amerikanistik at Uni Siegen. Dr. Waegner and I hosted a faculty exchange between NSU and Siegen, also on the theme of immigration, back around 2008. Then Dr. Daniel Stein took up the role of facilitator, helping arrange for a Memorandum of Understanding between our two institutions.

Future projects / Activities:

We hope that our “Mother(s) of Exiles” project – comparing attitudes towards immigration in Germany and the US – will result in a second book within this upcoming academic year. We are also expecting half a dozen Siegen professors or graduate students to visit us here in Virginia for the 2019 conference commemorating the 400th anniversary of Africans landing in Anglo-America.

Impressions of Siegen:

Siegen was unusually hot during our early June visit, but my colleagues and I truly relished the (human) warmth of our very cordial reception!

Prof. Andonaq Londo

Polytechnic University of Tirana, Albania

Host at the University of Siegen: Prof. Dr. Thomas Carolus Chair of Hydrokinetic Flow Machines
Institute of Fluid- and Thermodynamics

Current professional background:

I currently hold the title of full professor at the energy department of the Polytechnic University of Tirana – Albania, I have held this title since 1980. There I teach Fluid Mechanics, Fluid Machinery, Internal Combustion Engines, and Fluid Power. I’m leader of the scientific research group at Energy department for the above scientific field. I have served for three terms as Dean of my faculty. From 2003-2008 I have served as a director of the scientific research office at the Polytechnic University of Tirana. From 2004-2012 I was chairman of the German –Albanian Cultural Association “Robert Schwarz”.

Field of research:
  • Turbomachinery
  • Energy efficiency
  • Fluid Power
  • Fluid Mechanics
  • Internal Combustion Engines
  • Fluid Power
  • Renewable energy
Purpose of your last research visit:

My last visit to the University of Siegen was in July 2017. Once again, the Department of Energy at the Polytechnic University of Tirana organized, under the direction of the University of Siegen, a summer school in the field of energy and energy efficiency. During the summer school, Prof. Thomas Carolus met about 40 researchers and students from Germany, Albania, the USA, and China over three days. Students and young researchers from these countries discussed their work in the fields of turbine power and energy efficiency. This activity was funded by the Erasmus+ program and organized by Prof. Carolus. Mechanical engineering students from Siegen and Albania, who spent the summer semester at the University of Siegen on the Erasmus program, shared their ideas through lectures and poster presentations and discussed current energy issues. The first “Energy” summer school took place in Tirana in 2012. At that time everyone involved had great interest in repeating this success. We were able to do so, this time in Siegen, in July 2017. A continuation of this technical exchange on the international level would be most desirable for everyone involved, particularly given the international relevance of renewable energy.

Relation to the University of Siegen and/or to the local host:

I have spent much time in the University of Siegen in cooperation with Prof. Thomas Carolus. My first visit was in November 1996 for two months after I had received a DAAD scholarship to work with at the University of Siegen’s Institute for Fluid und Thermodynamics. In 1997 I became a member of the scientific research group lead by Prof. Thomas Carolus. I then worked in this team for more one year. Since my first time in Siegen, I have gained exchange experience not only in teaching, but also in scientific research with Prof. Thomas Carolus and his group. This was the greatest experience I have had while working with professors and institutions outside of Albania. Prof. Thomas Carolus has also spent much time at the Polytechnic University of Tirana. I would like to thank him for the great help given at our University in the preparation of new mechanical engineering teaching plans, which were needed for the restructuring of our higher education system in accordance with the Bologna process. Meanwhile, I would like to further emphasize his great work in supervising the work of diplomas of many Albanian students, who stayed for approximately 6 months at the University of Siegen, near the Institute for Fluid und Thermodynamics. Between 2001 and 2016, 12 Albanian mechanical engineering students have completed a Master's degree under supervision of Prof. Carolus.

Future projects / Activities:

Our future plans naturally follow from our research efforts in the past and present in the field of renewable energy, we will continue to write joint publications in future years. I and my Assistant Ardit Gjeta recently met with Prof. Carolus in Darmstadt, in April 2018 at the International Conference “ On Fan Noise , Aerodynamics, Applications and systems “ where we presented a paper together. I hope that our common research work will continue not just through continued joint participation in EU and German-funded research projects, but also in joint research in areas of mutual interest. Meanwhile, I hope that the exchange of students, academic staff and administrative staff will continue to grow with the University of Siegen.

Impressions of Siegen:

I consider Siegen to be my second city, after Tirana, where I grew up and became an engineer. There is an excellent climate of cooperation at the Chair of Hydrokinetic Flow Machines, under the lead of the erudite professor Thomas Carolus. I found the people of Siegen to be polite, warm, and always willing to help guests overcome any issues they might have during their visit. For me and my family, Siegen, and its University have become a very important part of our lives since we stayed there from 1997-1998. The fact that I had so many wonderful experiences, but now I also miss so many people is for me the greatest and most frustrating experience of my life abroad. I miss my partners at the institute of Siegen, everyone who works in the labs, dear people including Prof. Thomas Carolus, Frau Christine Krause and Dipl.Ing, Bernd Homrighausen. I miss Siegen's beer, fresh summer, spring flowers of many colors, and above all, my friends. I hope to one day return for another visit to Siegen.

Current professional background:

I have held a permanent position as a senior scientific researcher at the Republic Center for Structure Research (RCSR) of the Georgian Technical University (GTU) since 2003. The main research field of the RCSR is the investigation of micro- and nano-structures of materials, their properties, peculiarities and behaviour in different environments. My responsibilities are particularly related to studying the behaviour of high temperature corrosion/oxidation resistant materials, development of heat resistant coatings and new technologies related to these areas.

Field of research:
  • Materials Science; High temperature alloys and coatings
Purpose of your last research visit:

I have collaborated with the University of Siegen’s Chair of Materials Science and Testing for many years. My last visit there was for one week in April 2018, during which I held an intense schedule of meetings, scientific-research, as well as social activities to celebratethe chair’s 25th anniversary. This has allowed a good opportunity for an exchange of ideas, experience and information on the newest high temperature material related studies and projects going on in our two research groups (GTU and Uni Siegen). These exchanges occurred during private conversations, official meetings, and seminars given to an auditorium consisting of professors, lecturers, and students as well as the technical staff of the department.

Relation to the University of Siegen and/or to the local host:

Collaboration between our two groups has occurred for about 10 years. I met one of my co-hosts, Priv. Doz. Dr.-Ing. habil. B. Gorr from University Siegen, at an international conference in France where we discussed our topics of research and found lots of common areas of interest, we then began to plan our further collaboration. Since then I have visited the chair of materials science lead by Prof.Dr.-Ing. habil. H.-J. Christ many times in the scopes of projects funded by the AvH (Alexander von Humboldt) foundation or the DAAD (German academic exchange service). Besides the exchange visits my hosts and I also regularly meet at different international conferences dedicated to the topics of materials science.

Future projects / Activities:

Since our collaboration with the Materials Science chair of University Siegen has always been very fruitful, we plan to continue this also in future. We are always up to the new challenges of participating in both the large international and multi-partner research projects as well as the smaller ones.

Impressions of Siegen:

I consider Germany to be my second motherland because I have spent many years of my life in this country. I was honoured to work with many distinguished German (as well as international) scientists in the Forschungszentrum Jülich, BAM (Federal Institute for Materials Research and Testing) and of course the University of Siegen. I am always happy to come to Germany and especially to Siegen because there are so many colleagues and friends who make this place special for me.

Dr. Nowsheen Goonoo

Biomaterials, Drug Delivery & Nanotechnology Unit, Centre for Biomedical and Biomaterials Research (CBBR), University of Mauritius

Host at the University of Siegen: Prof. Holger Schönherr
Physical Chemistry

Current professional background:

I am a postdoctoral researcher currently working at the Biomaterials, Drug Delivery & Nanotechnology Unit, Centre for Biomedical and Biomaterials Research (CBBR), University of Mauritius.

Field of research:
  • High end biomedical applications of naturally-derived polysaccharides, for example seaweeds and Aloe vera.
Purpose of your last research visit:

The purpose of my last visit in March 2018 which lasted for 2 months was mainly to design new polymeric fiber based substrates and to test their efficacy in capturing various cancer cell lines such as pancreatic and breast cancer cells. This work was conducted at the Physical chemistry I Group, which is led by Prof. Schönherr.

Relation to the University of Siegen and/or to the local host:

I first met Prof. Schönherr in 2013, at a Polychar conference in Gwangju, Republic of Korea. We began to talk about our work and we found out that there was much to be gained by conducting research together. Since then there has been a close cooperation between our research groups. The University of Siegen provides expertise in cell work and also allows us access to certain equipment which is not yet available in Mauritius. Whereas myself and the CBBR can offer extensive experience and expertise into the scientific applications of Seaweed and Aloe vera, as they are native to Mauritius and the surrounding ecosystem. It is noteworthy to mention that I spent one year (2016-2017) working in Prof Schönherr’s group as a Georg Forster Postdoctoral Researcher (awarded by the Alexander von Humboldt Foundation). The research stay was very fruitful and led to several joint publications with Prof Schönherr but also with other departments of the University of Siegen.

Future projects / Activities:

For us it is most important to ensure that the current research is complete before we begin anything new. However it is never possible to know exactly how much longer the current research will take; the results can lead us in many different directions. We will continue to cooperate closely to test the effectiveness of different substrates with varying fiber topographies in capturing cancer cells. Thankfully it is relatively easy to share samples between Siegen and Mauritius by mail, and modern technology allows us to always stay in close contact.

Impressions of Siegen:

I found the working group of Prof. Schönherr to be warm and welcoming, they really made me feel at home very quickly. Siegen itself is very nice, and it is also not so big, coming from a small island I found Siegen easy to adjust to, except for the weather of course!

Prof. Seung Wook Jung

Konyang University, Republic of Korea

Host at the University of Siegen: Prof. Kristoph Ruland
Chair of Materials Science and Testing

Current professional background:

I am a Professor at the Department of Cyber Security Engineering at Konyang University in Nonsan, South Korea.

Field of research:
  • My research specialty is in blockchains, which is a specialised and decentralised way of recording economic transactions. This technology has many applications, for example it forms the basis for cryptocurrencies. My current research looks at how to use blockchains in smart energy grids. Smart energy grids also have many different uses, they can for example, make it easier for consumers to sell any electricity they generate back into the grid.
Purpose of your last research visit:

I came to Germany in order to cooperate on a project called "smart grid blockchain for end-to-end authentication and logging" with Prof. Dr. Ruland at the University of Siegen.

Relation to the University of Siegen and/or to the local host:

I studied my PhD at the University of Siegen a few years ago, Prof. Ruland was my supervisor.

Future projects / Activities:

Prof. Ruland proposed a project about blockchains for smart grids to the Pajako program (a German Ministry of Foreign Affairs initiative to foster partnerships with Japan and Korea). We have just made a memorandum of understanding (MOU) between the Universities of Siegen and Konyang to facilitate tighter cooperation in future. We will regularly visit both Universities to conduct this joint international project. By combining Prof Ruland’s expertise in smartgrids with mine in blockchains, we can create research that is greater than the sum of its parts.

Impressions of Siegen:

Siegen is a quiet and green city. I usually live in a larger metropolitan area so I find Siegen to be an easy place to relax because of the fresh air.

Prof. Jian Xiong

Harbin Institute of Technology, China

Host at the University of Siegen: Prof. Hans-Jürgen Christ
Chair of Materials Science and Testing

Field of research:
  • Mechanics of Lightweight Composite Materials and Structure (Composite Materials, Cellular Materials, Porous Materials, Biomaterials, Sandwich Panels, Lightweight Structures, Multifunctional Structures)
Purpose of your last research visit:

The purpose of my research visits is to set up a long-term research collaboration between the University of Siegen, Germany, and the Harbin Institute of Technology, China. The main research objective is to present the results of combining experimental, numerical and analytical studies to investigate the micro-structures and mechanical properties of the cellular structures in the mammal skull. The results of our research are expected to be useful for understanding the mechanical properties and damage mechanisms of cellular structures in the mammal skull and these fascinating features serve as suggestions to researchers to design or fabricate new bio-inspired materials to improve our lives.

Relation to the University of Siegen and/or to the local host:

I was previously a Humboldt Research Fellow at the Institut für Werkstofftechnik, University of Siegen from March, 2015 to August, 2016. The time before that was from September to December, 2013, when I was a visiting DAAD scholar. Prof. H-J. Christ was my host during both of these visits. I have joint research and publications with Prof. H-J. Christ and Dr. Arne Ohrndorf which present a systematic investigation on the failure mechanism and energy absorption of skull cellular bones under low- and medium-velocity impact loadings.

Future projects / Activities:

Our future plans naturally follow from our research efforts in the past and present in the field of lightweight cellular bones materials. We are planning to prepare a research proposal for the NSFC-DFG (Deutsche Forschungsgemeinschaft and National Natural Science Foundation of China) funding programme and write joint publications in the following years. During my latest visit to Siegen, I gave several presentations about my recent research work to other professors at the University. This may lead to some future cooperation with different departments on topics such as composite materials or automobile structures.

Impressions of Siegen:

The Radler beer is delicious, and so is the food, including the food from the University canteen on top of the mountain. The scenery in Siegen is very beautiful. I have been to Siegen four times and the University is an important part of my research life now. My hosts Prof.H-J. Christ, and Dr. Arne Ohrndorf have always been very nice to me and have helped me a lot in my research. I miss Siegen very much and hope to return again soon.

Exactly when we will do so depends on whether these institutions issue calls this year or in future years.

Impressions of Siegen:

Siegen is a multicultural city with a remarkable University where people and facilities make it possible to carry out different kinds of research. Especially in my field I find the University of Siegen to be a very strong partner with which to develop specialized research projects.

Prof. George Chagelishvilli

Georgian National Academy of Sciences, Georgia

Host at the University of Siegen: Prof. Holger Foysi
Chair of Fluid Mechanics

Current professional background:

Academic of the Georgian National Academy of Sciences, Principal Research Scientist at the Institute of Geophysics, Tbilisi State University, and a Principal Research Scientist at the Abastumani Astrophysical Observatory, Ilia State University.

Field of research:
  • Natural and engineering plasma and fluid dynamics;
  • Linear phenomena induced by shear flow non-normality;
  • Self-organization (including formation of spatiotemporal patterns) and turbulence in hydrodynamic and magnetohydrodynamic shear flow systems;
  • Aeroacoustics of turbulent shear flows.
Purpose of your last research visit:

The purpose of my research visits is the investigation of aerodynamic sound generation (aeroacoustics) which is a major subject of fluid dynamics, with applications in wide areas of engineering problems, such as aircraft jet engines, naval and automotive applications. The emission of noise from mixing processes and turbulence of engineering flows is to be reduced owing to modern regulations, which require a substantial reduction of the perceived sound levels. Working on this problem, we based our study on the rethinking of non-uniform/shear flow dynamics by the hydrodynamic stability community in 1990s. This approach, formed as a result of this rethinking, led to a breakthrough in the understanding and description of turbulence in different natural and engineering shear flows. Specifically, we adapted this trend of research to the aerodynamic sound generation in time-developing shear layers.

Relation to the University of Siegen and/or to the local host:

I have joint research and publications with Prof. Holger Foysi and Dr. George Khujadze where a new scheme of turbulence control is elaborated on the example of plane Couette flow. Our scientific interests also coincide in the field of aeroacoustics of shear flow systems. In my opinion the collaboration is quite productive and our perspective is to get closer to engineering flows.

Future projects / Activities:

Our future plans naturally follow from our efforts in the past and present. At first, we are planning to work on the control of the aerodynamic sound generation in time-developing shear layers. We also wish to apply the elaborated scheme of turbulence control to flows of practical interests, for instance, - to boundary layer flows

Impressions of Siegen:

Siegen is a pleasant city, very convenient for people who are visiting with a goal similar to mine: to live quietly and concentrate on science. However, it would be better if there were more guest house apartments at the University.

Dr. Ozgül Öztürk

Host at the University of Siegen: Prof. Dr. Ullrich Pietsch
Chair of the Department of Solid State Physics

Current professional background:

Research scientist at the University of Siegen physics department.

Field of research:

I currently work in the field of solid state physics, specifically my project is about nanowires.

Purpose of your last research visit:

I actually did my post-doctoral degree here in Siegen. That was when I began work on my nanowires project. Nanomaterials could be inserted onto the graphene, and then by combining this with polymers we are able to produce new kinds of optoelectronic sensors.

Relation to the University of Siegen and/or to the local host:

After finishing my PHD in Istanbul I came to Siegen originally for my post doctoral degree and worked with Prof. Dr. Ullrich Pietsch. After working in Istanbul for 8 years as an assistant professor, I have been offered a permanent position here in Siegen.

Future projects / Activities:

The University of Siegen is great for my research, so therefore I want to continue working on these projects here. We are currently performing experiments to optimise the graphene and nanowire samples further. As Richard Feynman, one of the first scientists to study nanomaterials, said, “there is plenty of room at the bottom.” So the possibilities with nanoscience are endless, with possible uses in the fields of biophysics, material science and pharmaceuticals.
I am also involved with a joint project in Jordan which uses a synchrotron, one of the most wonderful things about this project is that it highlights the power of science to bring people from different nations together. Even if their governments are currently not getting along with one another.

Impressions of Siegen:

Compared to Istanbul, Siegen is like a different planet! But I find it to be a nice change from living in a different city. I found everyone here, including Professor Pietsch to be very warm and welcoming to me. Siegen also feels like a nice place to raise my child.

Dr. Daria Berdnikova

Host at the University of Siegen: Prof. Dr. Heiko Ihmels
Department of Chemistry–Biology,
Chair of Organic Chemistry II

Current professional background:

I am a Marie Sklodowska-Curie fellow currently working on an independent European project here at the university.

Field of research:

Light-controlled interactions of organic molecules with nucleic acids.

Purpose of your last research visit:

On my last research visit, I performed investigations of organic molecules, which can be applied for light-controlled interactions with DNA. I design a molecule, synthesize it, check its photochemical properties, and then see if it can targetedly attack the nucleic acid upon irradiation. This approach can be used for killing undesirable cells, such as cancer cells. My current project is dealing with RNA instead of DNA, because this is more perspective for medical and biological purposes.

Relation to the University of Siegen and/or to the local host:

My former supervisor in Russia already had an established collaboration with Prof Ihmels here in Siegen, and they both encouraged me to apply for a short-term DAAD scholarship. After successfully receiving this scholarship in 2011, I came to Siegen to work with Prof Ihmels for the first time. Later on, I returned to Siegen several times to perform small joint projects. In 2017, I finally moved here for my current 2-years long project with Prof Ihmels.

Future projects / Activities:

We are currently 3 months into a 2-year research project. After we have some promising results, we can arrange some collaboration with biologists and biochemists to test our newly developed methods on fighting with cancer and bacterial cells and viruses.

Impressions of Siegen:

I’m originally from Moscow, which is very large, noisy and overcrowded city. Being in such a large city also made me feel separated from nature. So I adore Siegen because it has everything I need and I feel much closer to nature.

Dr. Gouri Shankar Giri

Host at the University of Siegen: Prof. Dr. Christof Wunderlich
Department of Physics,
Chair of Experimental Quantum Optics

Current professional background:

Postdoctoral Research Fellow at the Physics Department, University of Siegen

Field of research:

Quantum computing with trapped ions

Purpose of your last research visit:

I was a recipient of the Marie Curie Fellowship in order to work with Prof. Christof Wunderlich. Together we are developing essential elements for an ion trap based large-scale quantum computer.


Relation to the University of Siegen and/or to the local host:

I originally met Prof. Christof Wunderlich at the University of Sussex in the U.K, whilst we were working on a large-scale EU project. Conventionally, logic gate operations in ion trap quantum computers are realized with optical radiation (such as lasers). Prof. Wunderlich proposed and demonstrated a new scheme that ensures realization of logic gates using long wavelength radiation (such as microwaves). I was interested in working with him and I asked to join his research team in Germany. After successfully applying for the Marie Curie Fellowship in 2014, I took up my position as a Postdoctoral Research Fellow here in Siegen.

Future projects / Activities:

I will continue to work toward the development of ion trap quantum computer in collaboration with the research department here. I expect quantum computing to hugely advance in the coming decades, with the potential to change how we use computers in many different fields.

Impressions of Siegen:

It is certainly a good place to study, the living costs are low, and the campus, especially the physics campus is beautiful.

Purpose of your last research visit / Relation to the University of Siegen and/or to the local host:

The main target of my visit is to establish the collaboration with Prof. Holger Schoenherr in form of research study, exchange student, and bilateral joint fund. Actually, these items are connected, and will become each other’s support.

Future projects / Activities:

(1) Currently, we nailed down the specific research collaboration starting with fluorescence measurement and interpretation. Besides Prof. Holger Schoenherr and I, Sergy, an expert on fluorescence, will be involved. Intensified discussion can be conducted via email or network meeting (for example Skype). (2) Around the end of 2017, we will try to encourage student join the collaboration. From my side, I try to find financial sources to support master student to register as a PhD student in Siegen University. The student will be co-guided by Holger and me. By doing this, for one thing we can have more close collaboration, and for the other thing we can expand to larger scale collaboration (involve more project, student, and even professors). (3) The above-mentioned two aspects will make the bases for bilateral joint fund application. We hope that the health feedback of our lab-level collaboration can be expanded to depart-level, and even more.

Coordination of various activities within the Auger collaboration for publications and discussion with the students of the Siegen group of their master and PhD projects.

Relation to the University of Siegen and/or to the local host:

Postdoctoral position in the group of Prof. Markus Risse, 07/2013-03/2016

Future projects / Activities:

Research topics described above will continue also after the two planned research visits and surely reach into the next 1-2 years. There are more analysis topics, not yet mentioned, that may later come in addition; also in terms of hardware expertise (electronics of Auger detectors) and of the ongoing upgrade of the Auger Observatory, communications may prove useful.

To this end, the present visits would also be used to check options for further third-party funding of research visits (like DAAD). This includes mutual visits of various group members (Siegen-Prague), with the aim to strengthen the links between the two working groups.

Unsere Forscher-Alumni-Galerie befindet sich im Aufbau. Die Vorstellung weiterer Forscher-Alumni-Porträts folgt in Kürze.

Currently we are working on the Research Alumni Gallery. More profiles will be published soon.
