I am broadly interested in making systems more secure and reliable. Some of my current research thrusts include building tools to analyze, test, and protect software at scale.

Experience

I am currently a software engineer at Lacework's code security team.

Before that, I spent two years (2020–22) as a Computing Innovation Fellow (CIFellow), Postdoctoral Research Scientist, and member of the Secure Systems Lab (SSL) at Brown University, under the guidance of Professor Vasileios Kemerlis. I received my PhD in Computer Science from Columbia University in 2020, under the supervision of Professor Roxana Geambasu. My main research focus for the better part of the last decade has been in program analysis for software testing, operating systems security, and robustness and security of machine learning systems.

  • My dissertation on Cloud Service API Fuzzing
  • A literature review of automated software testing techniques (part of my candidacy exam)
  • A mostly up-to-date CV of mine
  • A recent talk on Blackbox Fuzzing
