My current 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 (

My PhD research focused on understanding the mechanism of regulation of a stress responsive signal transduction system in bacteria. I studied 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. I investigated the effect of light stress on the photosynthetic unicellular model microalga Chlamydomonas reinhardtii during my MSc research. This phytoplankton is exposed to considerable fluctuations in light intensity in the water column. I used an unbiased metabolomics and a targeted transcriptomics approach to understand how a dynamic network of genes, proteins and metabolites integrate into the observed stress-response.
