565 | There and Back Again: Amalie Migrates Home to GradCast

In this week's episode, host Mark Ambrogio interviews GradCast alumna Amalie Hutchinson, a PhD candidate in Biology. Amalie was a GradCast host and producer, ultimately serving two terms as Chair and Managing Editor. She returns to GradCast as she prepares to enter the fourth year  of her program (after a maternal leave – congratulations, by the way!). In her research, Amalie studies how hummingbirds use torpor, a state of inactivity characterized by a lowered body temperature and decreased metabolic rate, to preserve energy at night. While this phenomenon is not entirely unique to hummingbirds, the extreme temperature they lower their body to is. Amalie is currently looking at the energy demands of migration, using the wind tunnel at Western's Advanced Facility for Avian Research to study how hummingbirds consume energy over long-distance flights. In their conversation, Amalie and Mark also discuss their shared history with GradCast as well as ways of staying grounded as graduate students.
