Drexel Postdoctoral Fellow Roshell Muir

Dr. Roshell Muir is a postdoctoral research fellow in infectious diseases and HIV medicine, working in the lab of Dr. Elias El Haddad. She previously completed postdoctoral work in human immunology at The Vaccine and Gene Therapy Institute, and earned her PhD in medicine with a concentration in immunology at Queen's University Belfast.

Roshell presented her PhD thesis and published her work on the identification of type 3 innate lymphoid cells in the lung during acute respiratory distress syndrome (ARDS). Her postdoctoral projects include looking at the role of T helper–dependent B cell responses in acute HIV infection, and the characterization of Tfh function and germinal center B cell responses in a model of adjuvant HIV vaccination with long-term probiotic (Pbio) treatment.

Roshell collaborates with groups from the Thai Red Cross and Military HIV Research Program, and the University of Washington. She has coauthored with her colleagues in the lab as well as colleagues from other departments at Drexel. She has a keen interest in advocating for fellow postdocs and in graduate student curriculum development.

Drexel Postdoctoral Fellow Irene Headen, PhD, MS

Irene Headen, PhD, MS, is a postdoctoral research fellow with the Drexel Urban Health Collaborative in the Dornsife School of Public Health. Her research interests center around the social and structural determinants of racial/ethnic disparities in pregnancy outcomes. Dr. Headen's work investigates how differences in exposure to neighborhoods and other urban environments across the life course impact inequities in adverse pregnancy outcomes. Her doctoral work examined associations between long-term trajectories of neighborhood deprivation and women's risk of gaining too much or too little weight during pregnancy, both of which have adverse implications for maternal and infant health.

Previously, as a Maternal and Child Health Bureau Centers of Excellence postdoctoral fellow at the University of California, Berkeley, Dr. Headen studied how neighborhood environments interact with individual-level interventions to modify their effectiveness on pregnancy-related cardiometabolic outcomes. Her current work studies associations between place-based, early education initiatives, including Promise Neighborhoods, and maternal, child and family health outcomes in low-income communities. Dr. Headen earned her bachelor of science in brain and cognitive sciences from the Massachusetts Institute of Technology and a master of science and doctorate in epidemiology from the University of California, Berkeley.
