Giovanni F. Widmer, PhD

Molecular Biology of Protozoan Parasites, Microbial Pathogenesis

Cummings School of Veterinary Medicine 508-839-7944


For over 20 years, I have taught in the General Parasitology and the Biotechnology course and have mentored PhD, master’s degree and undergraduate students. My main research interests include the genomics, genetics and population biology of enteric pathogens and the interaction between host, intestinal microbiome and pathogens. Our research is focused on protozoan parasites and their interaction with the bacterial community of the gut. We are also involved in the refinement of animal models of enteric diseases.

I enjoy working on research projects that take a holistic perspective, rather than the more traditional “one bug – one disease” approach. The Department of Infectious Disease and Global Health (IDGH) at Cummings School embraces such a perspective and provides a collaborative environment that promotes innovative research.

I bring to this program my experience in molecular biology and genomics of microbial pathogens and my propensity for working with complex datasets as generated by high-throughput sequencing. I also have international experience working in Africa as a teacher with the United Nations Development Program.
