Ioannis Kaklamanis

Ph.D. Student in Computer Science

Yale University

I am a Ph.D. student in Computer Science at Yale University, advised by Prof. Fan Zhang. Before that, I obtained my Bachelor’s and MEng degrees in Computer Science from MIT.

My research focuses on cryptography for decentralized systems with privacy and transparency guarantees.
