I am an Assistant Professor in the College of Information Sciences and Technology at Pennsylvania State University. Before joining Penn State, I earned my Ph.D. at the University of Illinois at Urbana Champaign.

Research Interests: My research direction is at the intersection of Security, AI, and HCI to address the question: How can we design secure systems that improve the quality of human interaction and human data authenticity in digital ecosystems?

• Secure systems design to verify human interaction and data authenticity in AI/ML pipeline
• Privacy and security solutions for contextually situated communities
• Usable security and privacy for Web3/DeFi
• Human-in-the-loop [deliberative] governance for LLMs

Prospective Students: I’m looking for PhD students and interns to join my group. Please review the Interested to Join Us page and email me your CV.
