About

I'm a Senior Lecturer (=Assistant Professor) at the department of statistics and operations research, school of mathematical sciences, Tel Aviv University. Prior to that, I was a postdoctoral research associate at Princeton University's Program in Applied and Computational Mathematics, working in Amit Singer's group. I did my Ph.D. at the department of Computer Science and Applied Mathematics at the Weizmann Institute of Science in Israel, where Boaz Nadler was my doctoral advisor.

My research interests are broadly in the development of methodology for statistics and machine learning. More specifically, my current focus is developing tools for mapping and analyzing volumetric shape spaces. This is motivated by a key challenge in structural biology: the analysis of flexible proteins and other macromolecules from cryo-electron microscopy data sets.

RECRUITING! Looking for PhD/MSc students with a strong mathematical foundation. If you find my research interesting, please email me.
