E-mail: omribene@cmsa.fas.harvard.edu
I am a Postdoctoral Fellow at Harvard CMSA, mentored by Madhu Sudan. I've recently completed my PhD at Tel Aviv University, where I was fortunate to be advised by Noga Alon. After that, I spent a couple of months at Weizmann Institute, hosted by Moni Naor.

Research interests

Algorithmic and mathematical problems in computer science, with a focus on algorithms for large-scale structured data. I'm especially interested in sublinear-time and streaming algorithms, adversarially robust algorithms, and learning-based algorithms. I'm also interested in establishing mathematical foundations of more applied areas such as decision making, data mining, knowledge representation, and computer vision.

News: Check out our STOC 2021 workshop Robust Streaming, Sketching, and Sampling on Thursday, June 24.
