I am Associate Director of the Florida Institute for Cybersecurity Research and a University Term Professor. I joined the University of Florida in 2014 as part of the UF Rising to National Preeminence Hiring Program. My research focuses on the security of computer systems and networks. Recent work in my group has included securing embedded systems and protocols, establishing the trustworthiness of data and maintaing its provenance, mobile device security, protection of Internet traffic and the SSL infrastructure, and attacks and defenses against the cloud infrastructure. Some of my other research areas of interest include securing Internet routing, malware propagation, applied cryptosystems, adversarial machine learning, cyber-physical systems, and trustworthy computing. I received a National Science Foundation CAREER award in 2013, and was named International Educator of the Year within the Herbert Wertheim College of Engineering in 2017 for my work on developing global standards for securing digital financial services in the developing world. I am co-chair of the International Telecommunication Union's Security, Infrastructure, and Trust Working Group as part of the Financial Inclusion Global Initiative. I am a Senior Member of the IEEE and ACM. I'm technical program co-chair of the 2022 USENIX Security Symposium and conference general chair for ACSAC 2020 and ACSAC 2021
I am running for chair of ACM SIGSAC. My candidate statement and platform sheds more light on my service with ACM and goals for SIGSAC. Please consider becoming a SIGSAC member if you are not already so that you can vote in the upcoming election.
Note: We have built a world-class security research group at the University of Florida. I am looking for talented and motivated students students with an interest in systems security and doing inspiring work with real-world impact. The most important quality is intellectual curiousity and the ability to be a self-starter, but skills such as binary analysis, embedded systems, trustworthy computing, mobile security, or machine learning would be particularly useful. If you are not at student at the University of Florida and you are interested in my research, please apply to the program.
