About Me

My research explores foundational questions in the field of algorithmic fairness, such as:
(1) Characterizing the amount of friction between utility and fairness in various settings.
(2) Providing novel algorithms guaranteeing high utility and fairness in the face of limited or partial feedback.
(3) Making clever use of human feedback in the learning loop in auditing for unfairness.

I have also worked on and have ongoing interest in settings where machine learning algorithms interact with adaptive, strategic behavior.

In 2019, I had the privilege of spending an amazing summer at Berkeley, California, visiting the Simons Institute as a participant in the Summer Cluster: Algorithmic Fairness program.

In the Fall of 2017, I was fortunate to visit the University of Pennsylvania at the invitation of Aaron Roth and Michael Kearns.

I received both my MSc (Computer Science, Summa Cum Laude) and BSc (Computer Science and Mathematics) from the Hebrew University.

In my spare time, I shoot select 3-pointers on select basketball courts, speak fluent Arabic and not-so-fluent Japanese, blog about CS and non-CS stuff, and travel to cool places on pandemic-less times.
