Current Lab Members

Dr. Sassetti earned his PhD in immunology from UCSF and performed his postdoctoral training in mycobacterial genetics at the Harvard School of Public Health. Since 2004 his lab at UMass has focused on the application of new genetic approaches to understand tuberculosis disease progression with the goal of developing more effective interventions.

Ryan obtained a B.S. in Biochemistry from the University of New Hampshire. He then moved on to Duke University where he earned his Ph.D. in Molecular Genetics and Microbiology working in the laboratory of Dr. Jorn Coers. In the Sassetti lab, Ryan's work focuses on using a combination of natural genetic variation and genetic engineering to identify host factors/pathways associated with Mtb infection outcome and to define the mechanisms by which these host factors/pathways influence disease.

Mike is interested in the varied ways in which bacteria adapt to host and antibiotic pressures. In particular, Mike is investigating how homopolymers throughout the Mycobacterium tuberculosis genome can act as a source of genetic variation. Prior joining the Sassetti Lab, Mike graduated from Northeastern University with a degree in biology.

Peter’s work focuses on the integration of computational biology and microbial genomics to identify transient genetic variations within homopolymeric tracts that characterize the adaptive evolution of drug resistance/tolerance in Mycobacterium tuberculosis. Peter received his B.S in Biochemistry from Kenyatta University and M.S in Medical Biotechnology from Maseno University, both in Kenya and has previously worked  on cytokine polymorphic variations in endemic Burkitt lymphoma and genomic signatures of artemisinin resistance in Plasmodium falciparum.

Megan came to UMass in 2008, after graduating from the combined BS/MS program with a degree in Biomedical Engineering from Worcester Polytechnic Institute. She started in the laboratory of Dr. Jon Goguen studying the basic mechanisms by which Yersinia pestis induces disease and evades the host immune response. Megan transitioned to the Sassetti lab in 2013. Her work now focuses on trying to understand how host genetics influences TB pathogenesis and the implications this has regarding diagnosis, vaccination, and treatment.

Despite a concerted scientific effort, treatment for tuberculosis continues to be slow, difficult, and variably effective. In order to understand the many challenges involved in tuberculosis treatment, it's essential to study the genetic makeup of M. tuberculosis and its hosts. With a focus on genetically diverse mice, Charlotte contributes to a variety of the lab's ongoing projects. She received her B.S. at Worcester Polytechnic Institute, where she studied the mycobacterial stress response in the lab of Dr. Scarlet Shell.
