Rate My Professor Marcus Elstner

Prof. Dr. Marcus Elstner is Professor of Theoretical Chemical Biology at the Karlsruhe Institute of Technology (KIT), Institute of Physical Chemistry, a position he has held since 2009. He studied physics and philosophy at universities in Munich and Berlin, obtaining his diploma in physics. Elstner completed his PhD in Theoretical Physics in 1998 at the University of Paderborn, with research on quantum mechanical simulations of organic molecules conducted at the German Cancer Research Center in Heidelberg. Subsequently, he carried out postdoctoral research at Harvard University in the Kaxiras Research Group. Returning to Germany, he completed his habilitation in Theoretical Physics at Paderborn and then served as an assistant professor at the Technical University of Braunschweig. At KIT, he leads the Theoretical Chemical Biology group and is affiliated with the Institute of Nanotechnology and projects such as SIMPLAIX at the Heidelberg Institute for Theoretical Studies.

Elstner's research centers on developing and applying multiscale computational methods, including quantum mechanical/molecular mechanical (QM/MM) hybrid approaches and self-consistent-charge density-functional tight-binding (SCC-DFTB) techniques, to investigate complex biomolecular and material systems. His work addresses electron and exciton transfer processes, charge dynamics, proton transfer mechanisms, excited-state properties, and molecular dynamics simulations. He has advanced the DFTB methodology through extensive parameterization for various elements, enabling efficient treatment of large-scale quantum effects in biological environments. Prominent publications include "Hydrogen bonding and stacking interactions of nucleic acid base pairs: A density-functional-theory based treatment" (2001), foundational for nucleic acid interactions; "Atomistic simulations of complex materials: ground-state and excited-state properties" (2002); "Parameterization of the DFTB3 Method for Br, Ca, Cl, F, I, K, Na, Mg, Mn, N, O, P, and S" (2014); and numerous papers on charge transfer simulations using neural network-enhanced Hamiltonians. With 361 research works accumulating over 28,000 citations, Elstner's contributions have shaped theoretical chemical biology and computational biophysics. He supervises doctoral candidates in initiatives like the Research Training Group 2450 on computational nanoscience and delivers invited lectures on QM/MM simulations of transfer reactions.
