Penn grad students, postdocs and RAs, you are invited to lunch with interesting guests. Not a talk – they’ll take 10 minutes to introduce their work, then it’s pure conversation. Sandwiches and drinks served.

Alex Stahn is an assistant professor of psychiatry at the Perelman School of Medicine. His primary research focuses on the effects of gravity and extreme environments on circadian rhythms, neurostructural changes and cognition, and the effectiveness of physical activity as a countermeasure. He will be discussing his recent work on the brain effects of people who stay in Antarctica for extended periods of time.
