Jesse, who received his MD and PhD from University of Pennsylvania, is both a researcher and a practicing gastroenterologist and hepatologist. He studies how the insulin receptor functions and is learning about the role that biomolecular condensates within cells play in this process. How does he balance the intensity of being a clinician-scientist? “I used to ride my bike a lot, and go running with my wife. But lately I’ve found that rock climbing is a great ‘de-stresser.’ My climbing is all in the gym: I'm really terrified of heights, and I can't imagine myself doing it for real. But the combination of the physical workout and the sense of danger makes me stop thinking about work.” Since he was a teen, Jesse’s also been a big collector — with a particular passion for collecting vintage rock and roll t-shirts from the early 70s. “I love music, and the reason I got into this is that when I was in college, I really wanted a Clash t-shirt, but they were expensive and I couldn’t afford them. But over time, I’ve collected a lot of great shirts — like one worn by the staff at Woodstock in 1969. Today though, I'm trying to buy fewer of them; my wife says we don't have any room in our house.”
