Adithya Bhat
Staff Research Scientist
Team: Digital Currencies
Research areas: Fault-tolerant Distributed Systems, Applied Cryptography
Dr. Adithya Bhat joined Visa Research as a Staff Research Scientist in August 2023. Adithya received his Ph.D. in Computer Science from Purdue University in 2023. During his Ph.D., he worked on designing fault-tolerant State Machine Replication Protocols and Random Beacon Protocols. He also developed Rust libraries for the designed protocols. While at Purdue, he completed two internships at VMware Research and Visa Research. His last internship in 2022 was with the Digital Currencies team at Visa Research.
As a member of the Digital Currencies Team, Adithya’s research interests are broadly in studying highly concurrent trust-optimal decentralized technologies, protocols in the hybrid-trust model, analysis and study of public blockchain data to design and develop heuristics and technologies for highly scalable systems, and design and development of scalable privacy-preserving auditable secure computation. Adithya brings extensive knowledge in fault-tolerant distributed systems and applied cryptography as well as experience from industry. He has published over 12 research papers in top-tier conferences such as CCS, IEEE S&P, NDSS, and FC. He is excited to develop highly-scalable and concurrent payment systems and secure computation technologies.
