Steven Claypool is a product of California’s public education system having received both his BA and MA from UCSB. Steven’s PhD thesis focused on the trafficking of the neonatal Fc Receptor in polarized epithelial cells, work that was performed under the tutelage of Dr. Richard S. Blumberg at Harvard Medical School. For his postdoctoral studies, Steven switched gears and joined the laboratory of Dr. Carla Koehler at UCLA.  There, he began his investigation of mitochondrial phospholipid metabolism, work that is the foundation for the numerous studies ongoing in the CLAYPOOL Lab at Hopkins.
