Hung-Hsuan (Dean) Yen, MD

I am a surgeon and clinician-scientist from Taiwan, currently a visiting scholar at Stanford MARVL. I am also a Clinical Assistant Professor of Surgery at National Taiwan University College of Medicine and an attending general surgeon at National Taiwan University Hospital Hsin-Chu Branch.

My research focuses on surgical data science, surgical video analysis, and clinical AI application, with an emphasis on AI-based assessment of surgical quality, safety, workflow, and competency. My clinical interests include upper gastrointestinal surgical oncology and minimally invasive laparoscopic and robotic surgery.

Research

I work at the intersection of surgery and artificial intelligence. My current research explores surgical action recognition, temporal modeling of operative workflows, objective competency assessment, surgical quality and safety assessment, vision-language models for surgical video, and tool tracking and kinematic analysis.
