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.
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.
Teaching
Teaching Assistant · CYBER 440: Cybersecurity Analytics and Operations Capstone · Penn State IST · Fall 2026
Instructor: Dr. Nick Giacobe
Students analyze a complex cybersecurity incident across several sources of data and brief both technical and executive audiences. I hold office hours, help form and support the project teams, grade against the course rubrics, and occasionally lead a session. More about the course and my role.
I was awarded the Graham Endowment for Academic Excellence by Penn State IST in 2025.

Personal Projects
Things I build outside research, mostly to solve my own problems and to stay current with the tooling. Both are in progress.
- Swadesh: An iPhone app that reminds me to call family and friends. There is no account and no server, so everything stays on the device. Reminders are scheduled for an hour that is waking hours at both ends of the call.
- Diet Assistant: A diet assistant my wife and I use through Telegram. You type what you ate or send a photo of the plate, and it returns calories and macros. It runs on my own machine, so the record stays there.
