ETH Zurich

I am a PhD student at ETH Zurich under the supervisior of Andreas Krause in Learning and Adaptive Systems group. My current research work mostly focuses on modern instances of Experimental Design – a branch of statistics addressing the search for the most informative experiments in order to infer an unknown statistical quantity.

I am also interested in/have worked on Bayesian optimization, kernel methods, sensor selection, control, bandit algorithms and convex optimization. Some of my algorithms have found application in machine calibration, spatial analysis and directed evolution.
