Dr. Boris Striepen studied biology at the universities of Bonn and Marburg, and conducted undergrad research on liver flukes in Bonn, and trypanosomes in Bobo Dioulasso, Burkina Faso. Boris earned a PhD for work on parasite biochemistry with Ralph Schwarz, was a postdoc with David Roos, studying 
parasite cell biology, and started his own laboratory at the University of Georgia in 2000. In 2017 he moved to the University of Pennsylvania. Boris studies the cell and molecular biology of apicomplexan parasites. His current research focus is the parasite Cryptosporidium, a leading global cause of severe diarrhea and mortality in young children. His lab pioneered molecular genetics and mouse models for this important infection and leads a range of interdisciplinary efforts to understand fundamental parasite biology, and to advance translation towards drugs and vaccines. Boris is also engaged in education and training. He taught undergraduate and graduate classes, directed NIH training grant programs in parasitology, served as lecturer, faculty, and director of the Biology of Parasitism summer research course at the MBL for many years, and hosts the online Global Parasitology Seminar Series.
