Pratyush Mishra

Hi! I'm Pratyush. I will be starting as an Assistant Professor of Computer and Information Science at the University of Pennsylvania in Fall 2023. Meanwhile, I am working as a cryptographer at Aleo, a startup based on my research project Zexe (see below).

I recently completed my PhD in Computer Science at UC Berkeley under the excellent supervision of Alessandro Chiesa and Raluca Ada Popa.

Before that, I completed my BSc in EECS at UC Berkeley, where I did research under the guidance of David Wagner.

My research lies at the intersection of cryptography and computer security, with a focus on efficient realizations and applications of cryptographic proof systems and secure computation.

I am a co-author and co-maintainer of the arkworks ecosystem, which is a collection of libraries for zkSNARKs.
