This summer, Christeen Samuel, a sophomore at the University of Pennsylvania from New York City, spent 10 weeks in western Germany using technology to observe how the brain changes when a person makes an impulsive, aggressive choice, such as road rage.

The research opportunity in Germany came about when Samuel consulted her University Scholars mentor, Ruben Gur, a neuropsychologist in Penn’s Perelman School of Medicine, who told her about a longstanding partnership between Penn and RWTH Aachen University to conduct collaborative neuroscience research. The exchange allows German dissertation students to spend time at Penn and Penn students to do the same in Germany.
