I am a PhD student at the School of Computer Science and Engineering at the Hebrew University of Jerusalem, advised by Amit Daniely. My research explores foundational questions in the fields of machine learning, algorithmic fairness, and ethics in AI. I also have an ongoing interest in learning in the presence of strategic behavior.

My research is generously supported by the Apple Scholars in AI/ML PhD Fellowship.

I am involved with "TOC4Fairness", a research collaboration on the theory of Algorithmic Fairness, funded by The Simons Foundation, where I also co-manage a blog about Algorithmic Fairness, under the direction of Omer Reingold.

Yahav Bechavod, The Hebrew University




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.
