Statement of Research Interests
The focus of my lab is the study of microbial response in dynamic environments. Research in my lab combines classical microbiology and genomics/transcriptomics involving next-generation sequencing to determine microbial community structure and function under several environmental and host niches and conditions in an effort to elucidate how each attribute contributes to individual cell signaling and overall microbial community fitness, and host health. Specific projects include: “The Ecology, Transmission, and Pathogenesis of Mycobacterium ulcerans” and “Postmortem Changes and Translocation of Bacterial Community Structure and Function for use in Criminal Investigations.”
