I am a Professor and Director of Postgraduate Research; previously I was a Senior Research Scientist at Deutsche Telekom Labs and TU Berlin, and a PostDoc at the University of Toronto. I received a PhD in CS from the University of Virginia and a BSc in Informatics from the University of Bucharest.

Research

I am interested in stochastic models for computer and communication networks. I have also a special interest in optimal stopping problems and stochastic bandits, particularly on their fundamental limits in finite-time regimes.
