The 1992 doctoral dissertation titled Lanczos und Krylov-Verfahren für nicht-Hermitesche lineare Systeme marked the beginning of Marlis Hochbruck’s focused inquiry into numerical analysis. A German applied mathematician, she has built a career centered on matrix exponentials and exponential integrators, providing essential frameworks for the numerical solution of complex differential equations used in modern computational science.
Academic Foundation
Born in Krefeld in 1964, Hochbruck completed her high school education in her home city. She transitioned to the Karlsruhe Institute of Technology in 1983, where she dedicated her studies to Technomathematics. Her undergraduate tenure lasted until 1989, leading directly into her doctoral research. She completed her Ph.D. in 1992 under the joint supervision of Wilhelm Niethammer and Michael Eiermann.

Following her doctoral studies, Hochbruck spent time conducting postdoctoral research at ETH Zurich. Her professional trajectory then shifted toward university teaching and assistant roles, starting at the University of Würzburg in 1992. By 1994, she moved to the University of Tübingen. In 1998, she accepted a professorship in applied mathematics at the University of Düsseldorf, a role she chose after declining two other professorial offers from German institutions that same year.
Research and Professional Leadership
In 2010, Hochbruck returned to the Karlsruhe Institute of Technology to serve as a professor within the Institute for Applied and Numerical Mathematics. Her academic output includes significant collaborative publications such as the 1997 analysis of Krylov subspace approximations to the matrix exponential operator and a 2010 review of exponential integrators published in Acta Numerica. Beyond her academic research, she has served as a vice president of the Deutsche Forschungsgemeinschaft since 2014.
