He is a Fellow of the AMS, and his work has been awarded a Compositio Prize, a Packard Fellowship, a Simons Investigatorship, and a New Horizons Prize. In his youth in India, Bhatt spent most of his time playing cricket.

Craig Gentry

Craig Gentry is a Research Fellow at the Algorand Foundation. He works mainly on cryptography and complexity theory. In 2009, while a PhD student at Stanford and a summer intern at IBM, he constructed the first plausibly secure fully homomorphic encryption (FHE) scheme, which allows anyone to perform arbitrary computations on encrypted data while it remains encrypted. Such encrypted computation is useful in many settings (like cloud computing) where you may want to outsource the processing of data without giving away access to it. Ten years later, he (and many others) have made FHE much more practical, and based its security on well-studied problems, such as the "learning with errors’’ (LWE) problem, which in turn is related to the problem of finding short nonzero vectors in lattices. He also contributed to constructing the first plausibly secure program obfuscation scheme, which led to the better constructions that we have today, and to the construction of practical zero knowledge proofs, versions of which are used in blockchains today. For his work on FHE, he won the ACM Doctoral Dissertation and ACM Grace Murray Hopper Awards.
