About Me
I am a PhD student in Informatics at the College of Information Sciences and Technology, Pennsylvania State University, where I work on usable security and privacy for LLM and agentic systems, and on human-centered AI safety.
Before joining Penn State, I earned my B.S. in Information Technology from Jahangirnagar University and worked as a software engineer at Cefalo, developing GDPR-compliant archival management systems for the Norwegian foundation Stiftelsen Asta. Building privacy-preserving systems that non-technical users could actually operate, along with the research I did as an undergraduate, pushed me toward privacy, security, and human-centered design. That is what I work on now.
Research
I study how privacy is lost in systems built on large language models, and how it can be protected. Part of that is technical: measuring where leakage happens and designing pipelines around it. Part of it is human: whether the people affected can understand what these systems do and act on it.
Current projects:
- Third-Party Relational Leakage in LLM-Mediated Text Rewriting: Research exploration and pipeline design. Pilot experiments and analysis are feeding into an evaluation benchmark. With Dr. Anna Squicciarini.
- Modeling Metadata Release Under Differential Privacy: Contributing on the machine learning side, testing how ML can improve the release pipeline. With Dr. Anna Squicciarini.
Previous projects:
- Personhood Credentials and Zero-Knowledge Proof Based Age Verification for LLM Applications: Research question formulation, user study design, and usability pilots. With Dr. Tanusree Sharma.
- Explainability of Personhood Credentials (World ID): Multi-phase user research identifying explainability barriers in onboarding and verification, and an iOS application that teaches zero-knowledge proof concepts interactively.
- Systematization of Knowledge on Deepfake Audio: A review of deepfake voice detection methods, their vulnerabilities, and mitigation strategies, mapping out what is still unsolved.
I was awarded the Graham Endowment for Academic Excellence by Penn State IST in 2025.
