Samet Oymak Assistant Professor Electrical and Computer Engineering Cooperating Faculty with Computer Science University of California, Riverside Office: Multidisciplinary Research Building (MRB1) 169 Aberdeen Dr, Riverside, CA 92507 Email: lastname (at) ece (dot) ucr (dot) edu

I am an Assistant Professor of ECE at UC Riverside. I received my PhD degree in Electrical Engineering from Caltech in 2015.

My research lies at the confluence of machine learning, optimization, and statistics. I am broadly interested in finding principled solutions to contemporary
ML problems by using tools from optimization and statistics.

Key question: How to learn with provable guarantees by using minimal compute power, minimal human expertise, & imperfect data?

Current topics: learning with imperfect data, reinforcement learning, autoML & model compression, deep learning theory.

POSTDOC OPENING: We are looking for a postdoc at the intersection of reinforcement learning, control and networks. Please drop an email to me or Fabio.
