Bio
I am a final year Ph.D. candidate advised by Prof. Benjamin Van Durme at Johns Hopkins University. My research interests are structured prediction (e.g. semantic parsing, code generation, information extraction) and sequence modeling (e.g. machine translation, streaming sequence transduction).
Recently, I have been working on large language models (LLMs) projects including using reinforcement learning (RL) to improve model steerability and robustness, retrieval augmented generation (RAG) for long-form question answering, and model fine-tuning with preference and demonstration data.
On the job market: I am currently on the job market looking for industry positions. Don’t hesitate to email me if there is a potential fit.
