Saranna Fanning, PhD, is an instructor in neurology at Brigham and Women's Hospital and Harvard Medical School. She received her undergraduate BSc degree from the National University of Ireland, Cork, and completed her doctoral research work at Columbia University, New York; Carnegie Mellon University, Pittsburgh; and the National University of Ireland, Cork, which awarded her degree. As a PhD trainee, she studied cell-surface regulation in simple and complex cells called prokaryotes and eukaryotes, respectively. Dr. Fanning completed her postdoctoral training in the laboratory of Susan Lindquist, PhD, at the Whitehead Institute for Biomedical Research, where she became an expert in cellular models of protein toxicity and mechanisms of protein homeostasis related to Parkinson's disease (PD). Her work aims to describe genetic processes impacting protein toxicity in Parkinson's disease (PD) using genetic and biochemical approaches. Specifically, she aims to describe the role of lipids and fatty acids in alpha-synuclein toxicity in cellular, pre-clinical and human stem cell models.
