Sean Taylor Prigge, Ph.D.
Joint Appointment in Biophysics and Biophysical Chemistry
Research Interests: Malaria; Molecular biology; Immunology; Enzymology
Dr. Sean T. Prigge holds a joint appointment in biophysics and biophysical chemistry at the Johns Hopkins University School of Medicine. He is an associate professor of molecular microbiology and immunology and of biochemistry and molecular biology at the Johns Hopkins Bloomberg School of Public Health. His research focuses on molecular microbiology, immunology and malaria.
Dr. Prigge serves as the director of the Biophysics Core Facility, which supports Johns Hopkins Malaria Research Institute investigators who want to characterize macromolecules or macromolecular complexes.
He is currently engaged in investigating biochemical pathways found in the apicoplast.
Dr. Prigge received his B.A. from Amherst College and his Ph.D. from Johns Hopkins.

Malaria parasites contain an essential organelle called the apicoplast, which is thought to have stemmed from endosymbiosis of an algal cell, which previously incorporated a cyanobacterium. Due to its prokaryotic origin, the apicoplast contains a range of metabolic pathways that greatly differ from those of the human host. Dr. Prigge’s lab is investigating biochemical pathways found in the apicoplast, particularly those required for the biosynthesis and modification of fatty acids. This metabolism should require several enzyme cofactors such as pantothenate, lipoic acid, biotin and iron-sulfur clusters. Their focus is on these cofactors, how they are acquired, how they are used and whether they are essential for the growth of blood stage malaria parasites. Dr. Prigge and his team approach these questions with a combination of cell biology, genetic, biophysical and biochemical techniques.
