2016—2017 Harvard University, Research Fellow with Stephen Chong
- Awarded Harvard Physical Sciences Accelerator funding to commercialize my research on Shill, a secure shell scripting language.
2010—2016 Harvard University, Research Assistant with Stephen Chong
- Designed a novel software contract framework for enforcing a wide range of access control mechanisms.
- Developed a secure shell scripting language that combines capability-based security, software contracts, and operating system mandatory access controls to provide strong, composable security guarantees for scripts and legacy programs.
- Investigated techniques for applying software contracts and information-flow types to increase the security of programs relying on capability-based security.
- Designed a type system and enforcement mechanism that applied termination analysis to assure progress-sensitive information-security guarantees.
- Designed a type system and static program analysis to ensure the correctness of cryptographically enforced information erasure policies.
- Implemented an inter-procedural information-flow analysis for LLVM bitcode.
- Developed information flow and numerical abstract analysis frameworks for Java programs.
- Designed a sound technique for improving the efficiency of hybrid information-flow monitors using static analysis.
