Research interests
Microbiology (bacterial stress responses), Genetics

My research interests lie in uncovering how environmental bacterial species mediate stress responses to changing conditions in their local ecosystems. Students interested in a summer research project, independent study (BIOL396) or honours (BIOL498/499) please contact me via email.

Current projects:

Regulation in gene expression in Bacillus subtilis

This work is focused on studying a transcription control module that regulates gene expression in the model Gram-positive bacterium Bacillus subtilis following exposure to naturally-occurring antibiotics (vancomycin and daptomycin) and fluctuations in pH. Specifically, we are focused on understanding the protein-protein and protein – DNA interactions involved in turning gene expression ON in the presence of adverse stimuli.

Gut community structure of Blaberus discoidalis (In collaboration with Dr. Mel Hart)

This research project focuses bacterial community structure in the gut microbiome ofB. discoidalis, is a species of cockroach native to Central America. Microbiomes consist of a community of microorganisms that share a symbiotic relationship with the host organism. The gut microbiome of a host organism is generally responsible for aiding in digestion, development and also providing protection against invading pathogens. The preliminary aim of this study is to identify the genera and species of bacterial (both cultural and non-culturable) and parasitic nematodes that compose the gut microbiome B. discoidalis using 16S rDNA and ITS sequencing.
