Postdoctoral Fellow Learning & Adaptive Systems Group Department of Computer Science ETH Zürich Contact Address: CAB G 68, Universitatstrasse 6, CH-8092 Zürich E-mail: ilijab@ethz.ch Follow @ilijabogunovic

I am a postdoctoral researcher at the ETHZ Learning & Adaptive Systems group led by Prof. Andreas Krause. My research focus is on machine learning algorithms that are theoretically well-founded, robust and practically applicable. I am particularly interested in problems in sequential decision making and topics such as bandits, Bayesian optimization, submodular optimization, and reinforcement learning.

I received my PhD degree from École polytechnique fédérale de Lausanne (EPFL) where I was supervised by Prof. Volkan Cevher and co-supervised by Prof. Jarvis Haupt. Previously, I've done research internships at Twitter and MIT. I received my B.S. degree in electrical engineering from the University of Novi Sad and M.S. degree in computer science from ETH Zurich.
