Surafel Mulugeta, Ph.D., is a Research Associate Professor of Medicine in the Pulmonary, Allergy, and Critical Care Division (PACCD) of the Department of Medicine at the University of Pennsylvania.
Dr. Mulugeta received his Ph.D. in Biomedical Sciences in 1997 from Old Dominion University/Eastern Virginia Medical School. He completed his post-doctoral training at the University of Pennsylvania with Dr. Aron B. Fisher and Dr. Henry Shuman at the Institute for Environmental Medicine, and with Dr. Michael F. Beers at the PACCD. Following two years as a research associate in Dr. Beers’ laboratory, he joined the PCCD faculty in 2006.
Dr. Mulugeta’s early work comprises: a) the study of protein trafficking in the nervous system; b) the identification and characterization of an alveolar type II cell localized ATP binding cassette (ABC) transporter protein class A3 (ABCA3); and c) the trafficking and posttranslational molecular processing of pulmonary surfactant-associated proteins including Surfactant protein C (SP-C) and ABCA3. His early work also includes in vitro studies of SP-C and ABCA3 gene mutations that are associated with diffuse parenchymal lung disease.
His recent work focuses on broadening his study on SP-C and ABCA3 in order to further define the biology of these proteins in health and disease. His most recent effort is directed to understanding the cellular and organellar consequences caused by aberrant expression of mutant SP-C and ABCA3 isoforms that are associated with lung disorders through the utilization of both in vitro strategies and in vivo murine models of mutation-induced lung disorders.
