I work at the intersection of systems, machine learning, and algorithms, designing and building efficient, scalable AI systems. Recently, my work has focused on optimizing large language model (LLM) inference.

Short bio:

I am a Postdoctoral Fellow at MIT CSAIL. Previously, I was a Postdoctoral Fellow at Harvard University. I received my Ph.D. in Computer Science from the Technion. Prior to academia, I worked at Mellanox (now NVIDIA) as a Senior Software Engineer. I also received my B.Sc. and M.Sc. from the Technion.
