Andreas earned his first degree in biology at the Ludwig Maximilians University Munich and a Ph.D. with Alan Fersht in the chemistry department of the University of Cambridge. He then did a postdoc with Jeff Schatz at the Biocenter of the University of Basel before moving to Northwestern University in Evanston, IL as an Assistant Professor. Andreas graduate research investigated the mechanism of protein folding in vitro and his postdoctoral work studied protein import into and folding in mitochondria. Andreas own lab has tried to understand more complex biological processes such as the Ubiquitin Proteasome System in the mechanistic detail with which some simple enzymatic reactions are understood. The goal is that the findings will reveal novel principles of cellular regulation and allow us to engineer new functions into cells.
