Research Statement

Professor Wrase’s research centers around various aspects of string theory and associated areas in cosmology, mathematical physics and quantum field theory. In particular, he is working on understanding how one can describe inflation and dark energy in string theory and supergravity, as well as on connections between string theory and pure mathematics that go by the name moonshine.



Timm Wrase received his PhD from the University of Texas at Austin in 2008. Afterwards he held postdoc positions at the Max-Planck-Institute in Munich, Cornell University and Stanford University. Before joining Lehigh in January 2020, he was an assistant professor at the Technical University Vienna in Austria. In his research he is using string theory, the best understood theory of quantum gravity, to construct theoretical models that describe the cosmological evolution of our universe. His other research interests include supergravity, dualities in string theory and moonshine phenomena that connect different branches of mathematics.
