About
Biography
Sarah (Sadie) Meller is an MD/PhD candidate in the laboratory of Dr. Charles Greer, where she studies how immune cell activation may influence neurodevelopment. She is interested in the activities of microglia, which are brain-resident immune cells responsible for both maintaining homeostatic conditions necessary for normal neurodevelopment as well as orchestrating the brain’s response to environmental insults.
In her future career, Sadie aims to research how environmental hazards and infectious diseases impact brain development and help communicate children’s vulnerability to the health effects of climate change. She co-founded the Yale chapter of Physicians for Social Responsibility and Medical Students for Sustainable Future (PSR/MSFSF), helped organize the Planetary Healthcare Journal club and served as a student associate and alumni advisor for the Yale Center on Climate Change and Health (YCCCH).
