I am a Postdoctoral fellow at Harvard University, working with Michael Mitzenmacher and Minlan Yu.

I develop algorithms for data-intensive systems, with a focus on LLM inference, as well as streaming and queueing. I use theory and machine learning to guide efficient and reliable design.

Short bio:

I received my Ph.D. from the Department of Computer Science at Technion, advised by Roy Friedman. Before that, I worked at Mellanox (Nvidia now) as a senior software engineer. I also received my B.Sc. and M.Sc. from Technion.
