Atoms in the sunbath for a sustainable future
Cutting-edge research for a green future: As part of the MSCA COFUND project STAR (Sensing and Sensibility - Transcending Disciplines for a Responsible Future), Dr. Shanmugapriya Periyannan, a postdoctoral researcher at the University of Siegen, is investigating how individual atoms can use light energy to generate clean energy sources. For her innovative work, the (nano)materials scientist was awarded "Fellow of the Month" by the Marie Skłodowska-Curie Actions (MSCA) science organization in December.
When atoms "catch the sun's rays", new opportunities arise for environmental and climate protection: this is precisely where Dr. Periyannan's research comes in. In the "Chemistry and Structure of New Materials" working group, she focuses her research on processes at the atomic level and their potential for specific applications in the energy transition. "I want to understand how individual atoms can interact with light and thereby accelerate important reactions - for example to decompose pollutants or produce climate-friendly fuels," explains the researcher.
Her work focuses on single-atom photocatalysis. In this process, individual atoms are specifically placed on nanostructured materials in order to optimize their interaction with light. This tailor-made material development makes it possible to make chemical reactions more efficient and sustainable. "My goal is to combine fundamental nanoscience with real social challenges at the University of Siegen," says Shanmugapriya Periyannan.
Following her doctorate, which has already been funded by a Marie Skłodowska-Curie fellowship, Dr. Periyannan is continuing her scientific career at the University of Siegen as part of the COFUND project STAR. The EU project promotes international and interdisciplinary mobility as well as the transfer of scientific knowledge across disciplines, thereby strengthening Siegen as a research location.
In addition to her research, Dr. Periyannan is intensively involved in promoting young academics and in social dialog. She supervises students and is committed to equal opportunities in the STEM subjects. Topics such as neurodiversity and mental health are also close to her heart. She is also active in the Marie Curie Alumni Association (MCAA), where she initiated the podcast "The Curi(e)ous Minds" and contributes to the MCAA newsletter.
