Biography

I am a Postdoctoral Scholar in Professor Michael Franz's Secure Systems Lab lab at the Donald Bren School of Information and Computer Science at UC Irvine.

I obtained my PhD degree from Ghent University, Belgium in 2015 under the supervision of Professors Bjorn De Sutter and Koen De Bosschere. In my PhD dissertation, I proposed new techniques to improve the security, performance and applicability of Multi-Variant Execution systems. I was funded by the Agency for Innovation by Science and Technology. ReMon/GHUMVEE, the Multi-Variant Execution system I built during my research is available on GitHub.

My dissertation was awarded the IBM Innovation Award 2016 for an outstanding PhD thesis in Computer Science.

I am the creator and maintainer of Anti-Cheat Engine for Unreal Engine (ACE). ACE is a non-signature based native cheat protection tool for several online games based on Unreal Engine. ACE monitors the integrity each player's in-memory game state and hardens the game's UnrealScript interpreter. Some integrity violations ACE detects include native code patches in game files and system libraries ("hooks"), import/export table patches, virtual function table patches, replacement of critical game objects, bytecode patches, suspicious accesses to critical data structures, ...

ACE is/was a mandatory tool in most online gaming leagues that hosted competitions for Unreal Engine games, including ClanBase (now defunct), ESL, UTAssault, and Major League UT.
