Howdy! I'm Matan Shtepel: a Research Assistant at UPenn with Brett Falk and Pratyush Mishra where I am partially funded by a grant from the Sui Foundation. I work primarily in cryptography ∩ coding-theory and I am broadly interested in theory. Starting Fall 2024, I'll be joining CMU as a PhD student.

Previously, I completed ugrad in CS & Math at UCLA where I worked with Rafail Ostrovsky (see Publications). At UCLA, I founded and organized Theory@UCLA.

Outside of research, math, and building subpar academic websites, I also enjoy fashion, Australian rock, running, reading, snowboarding, and spending an unhealthy amount of time on looking at mathematician and scientists' bios on Wikipedia. Contact me for pretty much any reason!

Can you recognize the poster above my bed?

Yah? That construction on the board behind me? We found a flaw in the proof about 3 hours later 😎

As you may find me on a regular afternoon...

Academic Obligation

As an (aspiring) academic, I feel obligated to say there will be a blog coming soon. Don't worry! I will update twice during summer, then never again after 😏. If it will ever exist, it will probably be here.
