I am a PhD Candidate at Columbia University, where I work in the Security Group under Professors Suman Jana and Salvatore Stolfo. I am generally interested in Deep Learning based approaches to Program Analysis and Synthesis.


Microsoft Research 2021. Internship with Microsoft Research RiSE group advised by Todd Mytkowitz and Shuvendu Lahiri. Developed TOGA: A Neural Method for Test Oracle Generation using neural transformers and a specialized grammar to automatically generate unit tests that are highly effective at finding bugs (170% improvement over any other evaluated system). Published in ICSE 2022 and awarded ACM Sigsoft Distinguished Paper Award: paper.
