Assistant Professor

About Me

Since December 2019 I am affiliated with the Discrete Mathematics and Mathematical Programming group here at the University of Twente. Previously, I have had postdoc positions at Universität Bremen and Universidad de Chile. At the former, I was part of the group of Prof. Nicole Megow. At the latter, I spend a year at the Department of Industrial Engineering and a year at the Center for Mathematical Modeling.

As an applied mathematics researcher, I have a broad interest in Discrete Mathematics, Algorithmic Game Theory, Scheduling, Combinatorial Optimization, Complexity, Operations Research, and many related topics both of theoretical and applied nature.

Currently, I focus specifically on optimization under uncertainty, where we try to optimize our decisions even if part of the input data has some form of uncertainty.
