About Me

My research interests are Applied Cryptography, Blockchain, Security and Privacy. I am currently co-advised by Dr. Foteini Baldimtsi and Dr. Giuseppe Ateniese for my PhD in Computer Science. Currently, my primary focus is building cryptographic foundations for metadata-private instant messaging—where who talks to whom, when, and how often stays private.

Before joining academia, I used to craft scalable, distributed, and enterprise-grade products that solved real-world problems for millions of users. My contributions are battle-tested and I managed cross-functional teams. I have 5+ years of Software Engineering experience in the FinTech industry.

My undergrad thesis was supervised by Dr. Md Sadek Ferdous. He has been a true inspiration in my research journey.
