Tyler started playing CTFs when PPP was formed at CMU in 2009. He was the captain from 2011-2013 and led the team to their first victory at Defcon. In the past 6 years he has played in over 100 CTFs and learned a whole lot. After I graduated from CMU with degrees in Physics and Computer Science, after a brief stint as a PhD student in Quantum Computing Tyler returned to security, working on the DARPA Cyber Grand Challenge with David Brumley's company, where he now works full time.
