NEW: I have recently joined Coinbase to build a new crypto (currency + graphy) research group!

I am was a Senior Technologist (Security & Cryptography) in the Software Solutions & Algorithms group at Western Digital Research. I conduct research on modern cryptographic tools like secure multi-party computation, zero-knowledge proofs, attribute-based encryption, searchable encryption, etc. I investigate how these tools can be used to address problems in information security, privacy, and blockchain. I graduated from the University of Illinois at Urbana-Champaign with a PhD in Cryptography from the Computer Science department.

Previously, I was a Senior Staff Research Scientist and Team Lead in the Advanced Cryptography group at Visa Research. I joined Visa Research in early stages and helped build a strong crypto team. I also mentored several great interns: Srinivasan Raghuraman (MIT), Saikrishna Badrinarayanan (UCLA), Benedikt Bünz (Stanford), and Ioannis Demertzis (UMD), some of whom later joined as full-time.

At Visa, I worked on threshold schemes for symmetric-key encryption and password / biometric based authentication, and on cryptographic proofs for privacy and scalability in blockchains. I also helped develop new two-factor, multi-factor, and biometric authentication schemes.

I am/was on the program committee of EUROCRYPT 2022, PETS 2022, CBT 2021, ICDCS 2021, FC 2021, ACISP 2021, Indocrypt 2020, SBC 2020, CESC 2019, FC 2019, SBC 2019, FC 2018, and SAC 2017.
