About

I am currently a lecturer at the Faculty of Medicine, Siriraj Hospital, Thailand. I am interested in applying AI to healthcare in the real world setting, and building a community of AI researchers in Thailand. Until mid-2025, I was a researcher in Google Health working on advancing medical multimodal capabilities of Gemini and Gemma, Google's generative AI models. I focused on developing the vision-language ability of LLMs to create a performant system that can interact with users in a more natural way.

Before Google, I completed my PhD study under Professor Freédo Durand at MIT CSAIL, working on using synthetic data to solve various computer vision and signal processing problems. Previously, I attended Stanford University for a bachelor's degree in Physics.
