Ofir Geri
I am currently working as Software Engineer. This page is about my academic research. I was a Ph.D. student in the Computer Science Department at Stanford University. I was fortunate to be advised by Moses Charikar. Prior to that, I earned an M.Sc. degree in Computer Science from Tel-Aviv University, where I was advised by Michal Feldman.
My research interests are in algorithms and theoretical computer science, including streaming algorithms, sketching, approximation, and online algorithms.
