After 12 fantastic years at LSE, I am moving to the University of Bonn from August
2024, taking up a new Hertz Chair positions in the Transdisciplinary
Research Area in Modelling. I am looking for postdocs and
PhD students. Topics are broadly on fundamental questions at
the crossroads of mathematical optimization, theoretical
computer science, mathematical economics, and game theory. The
application deadline is 5 April for both positions.
