Ghedin Research Group

Our systems biology research program meets at the interface of molecular parasitology, microbiology, and genomics and focuses on the molecular basis of macroparasite (nematodes) adaptation to niches in their human hosts, and microparasite (virus and bacteria) diversity and interaction in transmission and virulence. The overarching question is: How do pathogens adapt to their hosts, and what is the evolutionary basis of this adaptation?
