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, and co-founder of CryptoDrop.
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. If you are not at student at the University of Florida and you are interested in my research, please apply to the program.
I am extremely honored to be named the Arnold and Lisa Goldberg Rising Star Associate Professor in Computer Science. Thank you to Arnold and Lisa Goldberg for generously endowing this professorship and supporting computer science at the University of Florida.
