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.

Dr. phil. Hyeongjoo Kim

Chung-Ang University Department of Philosophy, Republic of Korea

Host at the University of Siegen: Prof. Dr. Dieter Schönecker
Department of Philosophy,
Chair of Practical Philosophy

Current professional background / Field of research:

Philosophy of I. Kant. Metaphysic, Didactics of Philosophy


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

Cooperation of project "Sachunterricht vernetzen", Writing the paper "was heißt empirischer Satz"/ past supervisor


Future projects / Activities:

"Time Lecturer Support Project" of NRF(National Research Foundation of Korea): A Dialectic of Thought and Being: Kant-Fichte Comparison on their respective Attitudes toward descartes' Cogito-Thesis

Prof. Dr. Bo Song

Professor at Soochow University, China

Host at the University of Siegen: Prof. Dr. Holger Schönherr
Department of Chemistry,
Chair of Physical Chemistry

Current professional background:

Professor at Soochow University


Field of research:

  • Supramolecular assembly
  • Colloidal and interfaces
  • Fluorescence probes for bio-imaging


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.

Dr. Alexey Yushkov

Czech Academy of Sciences the Institute of Physics, Prague

Host at the University of Siegen: Prof. Dr. Markus Risse
Department of Physics,
Experimental Particle Physics

Current professional background:

Senior researcher at the Institute of Physics, Czech Academy of Sciences, Prague Coordinator of the physics task "Composition" of the Pierre Auger Collaboration


Field of research:

Experimental physics of ultra-high-energy cosmic rays


Purpose of your last research visit:

Discussion of details of the common work on analysis of the mass composition of ultra-high energy cosmic rays and of the photon searches using data of the Pierre Auger Observatory. 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.
