A picture of me

I lead the Global Cyber Intelligence team at Walmart. Previously, I led the Advanced Threat Research team at Webroot, and I was an Assistant Professor in the Department of Computer Science at the University of Colorado Boulder. I received my Ph.D. in Computer Science from the University of Florida, where I co-founded UF’s first and second cybersecurity startups, Skim Reaper and CryptoDrop. My work on payment systems security and ransomware has been covered by the Associated Press, Forbes, and numerous other media outlets.
