I am a Professor in the Department of Computer and Information Science and Engineering (CISE) at the University of Florida, where I currently serve as the Interim Department Chair. I am committed to the real-world impact of my research, and have co-founded three start-up companies (Skim Reaper, CryptoDrop and Pindrop Security). My team and I have also uncovered critical vulnerabilities in cellular and mobile networks, developed some of the strongest detectors of deepfakes and protections for voice-driven systems, and protected a wide range of other networked systems. Learn more about our work on my publications page.

I received a CAREER Award from the National Science Foundation in 2010, and was named a Sloan Fellow in 2014, a Fellow for the Center for Financial Inclusion at Accion in 2016, and a Kavli Fellow in 2017.

news

Apr 10, 2026 I spoke at the National Academies of Sciences, Engineering, and Medicine Standing Committee Meeting related to Social Security Administration Disability Determination about the future of AI and Fraud.
Apr 03, 2026 We had a paper accepted to both the 2026ACM Internet Measurement Conference (IMC) (in partnership with colleagues at Virginia Tech and UW-Madison) and the 2026 ACM Secure Development Conference (SecDev) (in partnership with colleagues at NC State). These papers make advances in cloud and cellular core security, respectively.
Sep 10, 2025 We had two papers accepted to the 2026IEEE Symposium on Security and Privacy. These papers make advances in fuzzing stateful systems and evaluating AI detectors in academic writing.
Jul 01, 2025 I have been asked to serve as the Interim Department Chair of CISE at UF.
