I am a PhD Candidate in Computer Science at Texas A&M University (GPA 4.0), working with Prof. Nitesh Saxena in the SPIES Lab. My research examines how end-to-end encrypted communication holds up when real people and AI systems enter the picture.
My work combines cryptographic protocol analysis, empirical user studies, and applied machine learning, with results published across leading venues in security, sensing, and machine learning.
Before research, I spent four years shipping production software: OAuth2/SAML systems in Germany, a debit-card API serving 3M+ banking customers in Bangladesh, and secure ASP.NET platforms for 100K+ users.
