Brief biography

I completed my Honours BSc degree with high distinction in biology and biochemistry at the University of Toronto in Mississauga. As an undergraduate, I investigated fungal biology and pathogenesis. I completed my MSc in the Department of Biology at the University of Western Ontario (now Western University, in London, Ontario), where I researched viral pathogenesis and evolution. As a Master’s student, I also began teaching in a classroom setting, contributing to collaborative projects, programming and performing data analyses. I obtained my PhD from the Department of Molecular Genetics at the University of Toronto, where I investigated gene-gene functional relationships; conditional rewiring of genetic interactions in response to environment and drugs; and Escherichia coli ribosome biogenesis and protein synthesis. I was involved in the development of systems biology approaches and computational tools. As a postdoctoral researcher at the University of Saskatchewan and a research specialist at the University of Regina, I investigated bacterial pathogenesis, antibiotic resistance, protein-protein and gene-gene interactions.

Starting in July 2023, research in my laboratory at UNB will use interdisciplinary approaches to investigate bacterial biology, genetic and protein-protein interactions, environmental adaptation, antimicrobial resistance, as well as host-microbe and microbe-microbe interactions. The laboratory will be equipped with state-of-the-art robotic instrumentation allowing large-scale bacterial colony pinning, liquid handling, and high-throughput screening. Additional instrumentation, including mass spectrometers and next-generation sequencers, real-time cell metabolic analyzers, RT-PCR and other equipment will be made available by collaborators. This research will be supported by federal, provincial and institutional funds.
