I am a Professor of Computer Science at the University of Central Florida with joint appointments in Computer Engineering and Modeling and Simulation. My research is in the area of security and privacy, and I have been recently focusing on topics such as machine learning and artificial intelligence, software and networked systems, internet of things and wearables, and blockchains. At UCF, I direct SEAL, where I have been fortunate to mentor several excellent students.

I obtained my Ph.D. from the University of Minnesota, in 2012, where I was a fellow advised by Yongdae Kim. I spent several years before and after then in the research and development industry, including working as a research engineer at ETRI (in South Korea) and as a (senior) research scientist at Verisign Labs (in Reston, Virginia).

Undergrauate Students

I am currently advising two undergraduate groups working on their senior design projects in the areas of AR/VR security (Sachin Mishra, Nolan Metcalf, Zakaria Antifit, Noah Lawton, Giullya Souza Santos, Ra'Id Naeem) and code repair with LLMs (Gavin Cruz, Vincent Lazo, Nicholas Wassom, Erik Tajti, Michael McGarvey).
