Senior Applied Scientist / AWS
Agentic RL, LLM post-training, and structured-data foundation models.
About
I work at the boundary between new machine-learning methods, production-scale systems, and scientific questions.
I build learning systems that connect reasoning, data, and the structure of the real world.
I am a Senior Applied Scientist in AWS AGI Foundations. My current work focuses on agentic reinforcement learning, LLM post-training, and foundation models for structured data, including time series and tables.
Before AWS, I was an AI Researcher at Shell, developing physics-informed and weakly supervised methods for scientific data. I earned my Ph.D. in Physics from Harvard University, where I worked with Xiaowei Zhuang on computational and super-resolution microscopy.
That path from molecular-scale imaging to foundation models continues to shape how I approach research: strong methods should respect the data, expose useful structure, and survive contact with real systems.
