Ever wonder how your brain decides when to start and stop eating? Most methods for studying appetite are too slow to catch the crucial neural circuits in action. Join Ranier Gutiérrez, PhD, professor at the National Polytechnic Institute of Mexico, as he unveils their new, high-resolution technique to help uncover how the brain controls appetite and the allure of highly palatable foods.

Inviting physiology majors, minors, and students interested in the program to meet department faculty and staff, learn about physiology course offerings, and explore ways to become more involved in the department.

Carrie McDonough, PhD, associate professor of chemistry at Carnegie Mellon University, studies how per- and polyfluoroalkyl substances (PFASs)—persistent environmental contaminants known as “forever chemicals”— accumulate and transform in the body. Using high-resolution mass spectrometry and ion mobility spectrometry, McDonough’s group investigates how molecular structure and chemical properties determine the impact of contaminants on aquatic food webs and human health.
