Marcus Elstner has been a Professor at the Institute of Physical Chemistry at the Karlsruhe Institute of Technology (KIT) since 2009. After his doctorate in theoretical physics and a postdoctoral stay at Harvard University (1999-2000), he was Professor of Theoretical Chemistry at the Technical University of Braunschweig (2006-2009). In his research, he investigates the structure, dynamics and function of complex macromolecules using computer simulations based on the fundamental concepts and methods of Statistical Mechanics and Electronic Structure theory.Qiang Cui received his Ph. D. at Emory University with Professor Keiji Morokuma in 1997. He was a postdoctoral fellow in the Department of Chemistry, Harvard University with Professor Martin Karplus, and started his independent career at the University of Wisconsin-Madison (2001-2017). Since 2018, he has been a professor of Chemistry at Boston University and holds courtesy appointments in Physics and BiomedicalEngineering.  His main research field is theoretical/computational chemistry and biophysics, especially the analysis of bioenergy transduction, membrane biophysics, protein dynamics and the nano/bio interface.Maja Gruden is a Full Professor of General and Inorganic Chemistry at the University of Belgrade - Faculty of Chemistry. She received her Ph.D. from the University of Belgrade in 2007. Her interest in theoretical inorganic chemistry led her to the University of Fribourg, Switzerland in 2009, where she completed her postdoctoral studies with Prof. Claude Daul. Prof. Gruden's research interests in recent years have focused on the application of Density Functional Theory (DFT) to transition metal chemistry and the understanding of the electronic structure of transition metal complexes with emphasis on the effect of spin states and vibronic coupling on reactivity, selectivity, magnetic properties, chemical bonding and spectroscopy.
