Megan Lindsay Povelones received her B.S. in Biology from Loyola University Maryland in 2002 and her Ph.D. in Cellular and Molecular Medicine at Johns Hopkins University School of Medicine in 2008. She then performed postdoctoral work in the United Kingdom, first at the University of Oxford and then at Imperial College London. Her research interests include single-celled parasitic organisms, including the human pathogen Trypanosoma brucei, which is the causative agent of African sleeping sickness. This devastating disease has an unusually high mortality rate, and affects tens of thousands of people in sub-Saharan Africa. In addition, these fascinating parasites have many unique biological properties, including the structure and function of their mitochondrion and the unusual arrangement of their mitochondrial genome.
