I am a vulnerability researcher at Raytheon SI Government Solutions where I conduct reverse engineering, static analysis, and vulnerability research. In my spare time I participate in CTFs and enjoy watching/playing many sports including golf, surfing, softball, basketball, bowling, and football.

Prior to working at SI, I was in the Cyber Systems & Operations group at MIT Lincoln Laboratory focusing on malware analysis, vulnerability research, and intrusion detection. I earned my M.S. and B.S. in Computer Science from the Georgia Institute of Technology in 2010 and 2009 respectively. While at Georgia Tech I studied areas of information security including privacy and side-channels with my advisor Patrick Traynor.

In my pre-academic life I was known as Flip, the keyboardist for the industrial metal band Crossbreed. We were signed to Artemis Records and toured the U.S. and Canada in support of our album, Synthetic Division. We received regular rotation on national radio stations and our video for Underlined was featured on MTV2 and MTVX.
