Nhan H. Pham

I am a Staff Research Scientist at the IBM Thomas J. Watson Research Center in Yorktown Heights, NY. My research focuses on Large Language Models (LLMs) for enterprise data management, particularly Text-to-SQL systems. I also work on stochastic optimization methods for machine learning, deep learning, and reinforcement learning.
