About Me

Hello!

I am currently a second-year computer science Ph.D. student at Brown University. My research focuses on privacy-preserving cryptography, where I aim to develop technologies that enhance online privacy and address the growing vulnerabilities of our digital lives. I am advised by Dr. Anna Lysyanskaya.

My current research interests include:

• Anonymous tokens with hidden metadata
• Mercurial signatures and their applications
• Cryptographic image authentication to combat misinformation with the rise of AI
• Onion encryption for secure and private message routing
• Efficient, round-deterministic threshold signature schemes
• Federated learning for decentralized and privacy-aware model training
• Private Set Intersection (PSI) and related problems such as heavy hitters, with applications in secure and private ride-sharing systems

Beyond Research

I love to run, swim, and bike :)

I also volunteer on the Opportunity Review Team for the American Red Cross.
