Faculty Investigator: Dr. Matt Wargo, Assistant Professor in Microbiology & Molecular Genetics
Dr. Wargo received his B.S. in Biological Sciences from Susquehanna University where his undergraduate research focused on the ecology of freshwater diatoms. He then received an M.S. in Botany from Texas A&M University studying dinoflagellate nuclear proteins. Dr. Wargo received his Ph.D. from Dartmouth College, where he studied the regulation of eukaryotic flagellar motility with Dr. Elizabeth F. Smith. For postdoctoral research, he studied microbial pathogenesis with Dr. Deborah Hogan at Dartmouth Medical School and mammalian lung biology with Dr. Laurie Whittaker (Leclair) in the Pulmonary Division of the Department of Medicine at UVM, before joining the Department of Microbiology and Molecular Genetics in 2009.Members:
-Grad Students: Jamie Meadows (MMG), Adam Nock (MMG), Graham Willsey (CMB)
-Undergrad Research: Yuzo Kevorkian (MMG), Dong Yi Chen (NSF REU)
Accepting rotation students: Yes
Major Research Projects: We are interested in Gram negative opportunistic pathogens and the environmental and host-derived cues that they use to transition from their environmental niche to the site of infection. We use forward and reverse genetics coupled with basic microbiology and biochemistry to discover and characterize bacterial detection systems used to sense their environment. For the organism that is the focus of our laboratory, Pseudomonas aeruginosa, these detection systems are often coupled with metabolic pathways to utilize the host-derived signal. Therefore, we also study the links between host detection and metabolism of host-derived compounds and the impact of these processes on infection.We are interested in this topic for two primary reasons:
- To establish and propagate an infection, bacteria must properly respond to the environment of the infection site. Because many bacterial signaling systems and transcriptional regulators have no homologs in humans, these systems could be effective therapeutic targets.
- More than 60% of genes from well-studied bacteria have no known function. By using a genetic approach, we have been the first to ascribe function to nearly 20 genes in P. aeruginosa. This satisfies a basic sense of curiosity driven discovery, but is also a key contribution to the study of bacteria, because without established functions –omics technology can get you only so far.
