I am a Senior Lecturer at the Faculty of Engineering at Bar-Ilan University (BIU).
I am interested in what I like to think of as “machine-learning-enhanced statistical signal processing”, an emerging interdisciplinary field where signal processing, machine learning, estimation theory, and some elements of information theory meet. The kinds of problems I currently focus on are related to communication systems, localization, sensing and compression. My research spans both pure theoretical aspects as well as application-driven practical problems.
Before joining BIU, I spent three wonderful years as a Postdoctoral Associate at the Research Laboratory of Electronics, Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, where I had the pleasure of working with Prof. Gregory W. Wornell. Prior to that, I was a Postdoctoral Fellow at the Department of Computer Science and Applied Mathematics, Weizmann Institute of Science, Rehovot, Israel, where I had the opportunity to work with Prof. Boaz Nadler. I received the B.Sc. (magna cum laude), M.Sc. and Ph.D. degrees in Electrical Engineering from Tel-Aviv University, Tel-Aviv, Israel, in 2013, 2015 and 2020, respectively, where I was very fortunate to have Prof. Arie Yeredor as my supervisor.
