Johannes Gierschner received his Ph.D. in Physical Chemistry at the University of Tübingen (UT), Germany, in 2000. After stays at UT, Univ. Mons (UMons), and at Georgia Tech, Atlanta, he joined the Madrid Institute for Advanced Studies - IMDEA Nanociencia- in 2008 as a Senior Research Professor (Ramón y Cajal fellow 2008-13; I3 and IED accredited). In 2014, he habilitated at UT and holds an Adjunct Professor (Privatdozent) position there since then. JG is regular visiting researcher at University of Valencia (since 2014), and at Seoul National University (SNU; since 2008), and held Visiting Professor positions at SNU and UMons (2014/15). His work integrates optical spectroscopy and computational chemistry to elucidate structure-property and -process relationships in conjugated organic materials for optoelectronics and energy conversion.
JG is further dedicated to consolidate the community knowledge through regular insightful, educative reviews and international lecture series in photophysics of organic materials. Moreover, during the last years, he is increasingly committed to 'scientific integrity' seminars for students & researchers.

Indranil Bhattacharjee is working in the field of ‘Understanding the inherent photophysics of the Donor-Acceptor based pure organic molecules’. Started from his PhD. onwards he was keenly interested in the design, synthesis and characterization of those materials. In 2014 he joined Shiv Nadar University for his Ph.D. (with Dr. Debdas Ray) in the field of Physical and Material Chemistry. After completion of his Ph.D., he started his postdoctoral research with Dr. Shuzo Hirata at University of Electro-Communications, Japan as a UEC postdoctoral fellow. Since 2022, he has been working at IMDEA Nanociencia as MSCA-IDEAL postdoctoral researcher, with Prof. Reinhold Wannemacher and Prof. Johannes Gierschner.

MEET DR BHATTACHARJEE
Concept of Dr Bhattacharjee’s project is to understand the photophysics of the pure organic photocatalyst and unveil the inherent mechanism for the betterment of the future research.
His current research plan is most dependent on the uses of various state-of-art instruments, and there are very few institutes where he can access all these under the same roof. In addition to that, IMDEA Nanociencia also has a significant impact at the league of the researcher, and that will amplify his research in the outer world.
Research in the field of OPCs has been highly enhanced in the last few years.
Dr Bhattacharjee will be involved in the quantum mechanical calculations and analysing the data using state-of-the-art ultrafast transient absorption technique as well as various other spectroscopic tools. Handling these kinds of instruments will enhance his capability and analysing the data will also intensify his knowledge not only on this specific field but also will help for better understand the various prospect of physical chemistry. He is quite sure that this fellowship will increase his potential as a researcher and also working in this project will broaden the path of his future research.
