2010—2016 Harvard University, Research Assistant with Stephen Chong

Language-based authority control

• Designed a novel software contract framework for enforcing a wide range of access control mechanisms.

Integrating programming Language and operating system information security 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.

Accrue: providing language-based security guarantees proportional to programmer effort

• 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.

CHILI: enabling the execution of code of unknown origin while eliminating classes of security attacks

• 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.
