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.
