Nat Chairuengjitjaras

Nat (Pitchaya) Chairuengjitjaras is a Master’s student (’26) in Health Informatics at Yale and a Sustainable Health Initiative (SHI) Fellow. She is passionate about improving healthcare delivery and patient outcomes through informatics tools such as data analytics and large language models (LLMs), with a focus on low-resource settings and pediatric care.

Before Yale, Nat worked as a primary care physician in Thailand and gained additional clinical exposure through rotations in the U.S. and Canada. Her firsthand experience with the challenges of delivering care in low-resource settings inspired her to join a health tech startup focused on validating and implementing a medical LLM to support clinical decision-making. There, she also collaborated on market research, pitched the product to healthcare and business leaders, and helped the team earn second runner-up in a startup competition. Her work contributed to improving access to timely care and specialist-level support in underserved areas. In parallel, Nat supported digital health research at the Center of Excellence in Hepatitis and Liver Cancer, Chulalongkorn University, where she helped expand telehealth services and develop a national e-registry and screening platform for hepatitis B and C.

As an SHI Fellow, Nat is excited to mentor student teams, support global health ventures, and connect peers with Yale’s innovation resources. She currently works as a research assistant in the Pediatric Health Services & Implementation Research Lab and the Clinical NLP Lab at the Yale School of Medicine, and serves as clinical lead at the Laboratory of Intelligent Global Health & Humanitarian Response Technologies (LiGHT), facilitating partnerships with hospitals in Thailand. In her free time, she enjoys spinning, running, and perfecting her matcha latte.
