The Gastronauts Podcast Team

Peter Weng is the host for The Gastronauts Podcast. Peter is currently an MD-PhD student at the Duke University School of Medicine, where he studies how cells in the gut have developed the ability to rapidly communicate information about nutrients to the brain in the laboratory of Dr. Diego Bohórquez. During his medical training, Peter learned the value of effectively communicating a patient’s story to the entire healthcare team. Peter hopes to share his experiences and provide additional resources for prospective graduate students. He serves as an undergraduate mentor in the American Physician Scientists Association and was an editor for the Duke Science Review.
