Jussi Behrndt studied Mathematics and Physics at the Technical University of Berlin and obtained his Masters degree in 2002 and his Doctoral degree in 2005. From 2005-2008 he held the position of Research Associate at the Technical University of Berlin and a Postdoc position at the University of Groningen, Netherlands. Behrndt completed his Habilitation in Mathematics in 2008 and held appointments as visiting professor at the Technical University of Vienna and the Technical University of Berlin, before becoming a full professor in Mathematics at Graz University of Technology in 2011.
Behrndt's research focuses on functional analysis, operator theory, and mathematical physics, with an emphasis on spectral theory and perturbation methods for differential operators. Among his current research interests are Schrödinger and Dirac operators with singular potentials, related approximation problems, Dirichlet-to-Neumann maps and Titchmarsh-Weyl m-functions, and various abstract extension theory problems for symmetric operators and relations.
Jussi Behrndt has published more than 100 articles in mathematical journals and conference proceedings volumes, and organized several international math conferences and workshops in the area of operator theory. His most recent monograph "Boundary Value Problems, Weyl Functions, and Differential Operators" was published at the beginning of 2020 in the Springer book series Monographs in Mathematics.
Professor Behrndt is currently teaching for the Department of Mathematics the course MATH 258: Topics in Geometric Analysis (Winter Quarter).
