Dr. Levi Guest Stars on the Podcast

This episode of Scrubcast features Dr. Benjamin Levi, our honored guest at the 2024 Emile F. Holman Lecture. He shares insights on his motivation for merging plastic surgery with critical care, emphasizing the holistic care of burn patients from acute treatment to long-term reconstructive surgery.

Levi’s primary research focus is on heterotopic ossification. He explains how injuries can lead to bone formation in unintended locations and the implications for patient care. He highlights how each of the places he’s lived, worked, and studied contributed uniquely to his research and clinical practice.

Holman Lecturer

Benjamin Levi, MD

“Elevating musculoskeletal and mental fitness from the farm to the frontier”

Dr. Benjamin Levi is a surgeon scientist whose passion for science started here at Stanford when joining the Hagey laboratory in 2009. He is grateful for his continued connection, collaboration and sponsorship from Drs. Longaker, Chang , Wan and many others in the Department of Surgery and Institution. Dr. Levi did medical school at Northwestern University, residency in plastic surgery at University of Michigan, post-doctoral fellowship at Stanford and surgical critical care and burn fellowship at Massachusetts General Hospital. He currently holds the Dr. Lee Hudson-and Robert R. Penn Chair in Surgery and is the Division Chief of General Surgery at UT Southwestern. His division is comprised of an incredibly talented, diverse and collaborative team of 25 surgeons and over 20 scientists whose mission it is to enhance the human experience. He also directs of the Center for Organogenesis Regeneration and Trauma (CORT) which is one of the few centers whose focus it is to advance science and elevate patient care for adults and kids afflicted by trauma. He has published over 150 peer reviewed manuscripts, many in high impact journals, holds 3 R01s and 7 DOD awards. He invests heavily to support the professional development and mental fitness of the teams he works with. He is most proud of the culture of wellness, diversity, connection and collaboration his teams have established in their division, research center and laboratory.
