The spokespersons represent and lead the graduate school and report to the partners and the Helmholtz Association. The spokespersons are nominated and elected by the Institutional Board for a term of three years.


Nina Rohringer recently joined DESY as a leading scientist and is a full-professor at the 1st Institute for Theoretical Physics of UHH. Her research interest is the study of ultrafast interaction of x-rays with matter, in particular the development of new nonlinear x-ray spectroscopic and imaging techniques at x-ray free electron lasers. In addition to her expertise in theoretical and numerical physics, she is also actively involved in experimental campaigns at national and international XFEL sources and is a pioneer in studying stimulated x-ray emission and scattering processes. N. Rohringer bridges the gap between theory, modeling of experiments and data analysis. Contact Information: Tel.: +49 40 8998-6258, E-Mail: nina.rohringer@desy.de.

Sabine Le Borne is heading the Department of Numerical Mathematics of TUHH. Her research interests lie in numerical linear algebra, numerical solution of partial differential equations, hierarchical matrices, iterative solvers for large equation systems, kernel-based approximation methods and the transfer of mathematical methods to science and engineering. At TUHH, she has been a member of the Faculty Board of the School of Electrical Engineering, Computer Science and Mathematics since 2013 and served as chair of the examination board of the study program B.Sc in Technomathematics since its inception in 2012. She is an associate editor of the SIAM Journal of Matrix Analysis (2013-2018). Contact Information: Tel.: +49 40 42878-3874, E-Mail: leborne@tuhh.de.

Matthias Rarey, computer scientist by training, Matthias Rarey is a full-professor at Universität Hamburg heading the ZBH РCenter for Bioinformatics since 2002. His research interests are in the development of computational methods for cheminformatics, structure-based molecular design and structural bioinformatics. He has 25 years of experience in developing computational methods for life science applications and is part of the German de.NBI consortium for bioinformatics infrastructure. At UHH, he co-initiated the interdisciplinary study programs B.Sc. Computing in Science and M.Sc. Bioinformatics. Currently, he is heading the PhD committee of the Informatics department. M. Rarey is Spokesman of the German Fachgruppe Bioinformatik, Associate Editor of the ACS Journal of Chemical Information and Modeling and a liaison professor for the Studienstiftung des deutschen Volkes.
