Research

• I am a PhD candidate studying Program Analysis at Boston University under the supervision of Manuel Egele and Hongwei Xi.
  I am interested in developing program analysis techniques that discover unknown vulnerabilities hiding in programs and exploring language based security approaches that defend such programs from attacks. I am also interested in how advanced type systems can help improve the reliability and security of systems software.
