About Me

ā€œA watched loss curve never converges.ā€ - A Wise Programmer

I’m a third year Ph.D. candidate advised by Arjun Guha in the Programming Research Laboratory at Northeastern University. My interests lie at the intersection of NLP, programming languages and systems. I focus on deploying CodeLLMs safely in software applications and training CodeLLMs for novel domains.

My work spans a range of settings — from low-resource programming languages and robotics to education, 3D modeling, and beyond. I ground my research in mechanistic interpretability: the belief that model capabilities emerge from identifiable, analyzable components within the model itself.
