Research
       I am interested in work related to program analysis (static and dynamic analysis), runtimes, programming models, parallel and distributed system software, and concurrency.

I enjoy desigining and implementing analyses and runtimes for concurrent systems considering tradeoffs between performance and correctness across the software stack.

I am currently an Applied Scientist at the Automated Reasoning Group at Amazon. I am working on enforcing correctness properties on AWS services at scale. Previously I was a Researcher at Samsung Research, in SRA's Artificial Intelligence Center, where I worked on building systems targeting reliability, performance, and explainability.

I earned my PhD. under the guidance of Prof. Michael D. Bond. Our research group at OSU: PLaSS. My research was directed towards low-overhead, state-of-the-art solutions that enforce strong semantics in ill-synchronized programs using hyrbid static-dynamic analysis, runtime support, compiler transformations, and software or hardware transactional memory, all on commodity hardware. I had the opportunity to collaborate with Prof. Milind Kulkarni at Purdue on several projects that are part of my PhD dissertation.
