Prof. Dr. Christian Liedtke


Algebraic Geometry

Academic Career and Research Areas

The field of research of Professor Liedtke (b. 1976) is algebraic geometry situated at the nexus of classical, complex and arithmetic geometry. His research deals with the classification of algebraic surfaces (in particular K3 surfaces and surfaces of general type in positive characteristic), elliptic curves and fibrations, fundamental groups and the construction of rational curves.

Professor Liedtke studied mathematics at the University of Göttingen and the University of Warwick from 1996 to 2001 and graduated in 2001 under the supervision of Professor Catanese. He subsequently performed his doctoral studies under the supervision of Professor Faltings at the Max Planck Institute (MPI) for Mathematics in Bonn. After obtaining his doctoral degree in 2004 he worked as a research assistant at the University of Düsseldorf and from 2009 to 2011 he conducted research at Stanford University as a recipient of a DFG-scholarship. After his habilitation (2011), he was a Research Associate at the University of Bonn; from 2013 until his appointment as Associate Professor in 2017, he was Tenure Track Assistant Professor at TUM. Prof. Liedtke has been a Full Professor at TUM since 2022.
