I earned both an undergraduate and master's degree in Environmental Health from the University of Waterloo and completed a second master’s in Toxicology at the Royal Melbourne Institute of Technology in Australia. I was awarded with a doctorate of Environmental Medicine (Environmental Health Sciences, Exposure Assessment and Toxicology) from the Department of Environmental Medicine at the New York University School of Medicine. I play an active role in the Society of Toxicology, the Society of Toxicology Canada, and the Society of Environmental Toxicology and Chemistry.

My goal is to make my mark by improving human health and human health policy using science-based research. My work to date has resulted in publications and grants that strive to protect Canadians from the adverse health effects of a wide variety of toxicants such as pesticides, toxic metals, and nanoparticles. I primarily work with local and remote Indigenous communities on issues that concern them and implement novel technological tools and statistical methods such as 3D printing, AR/VR, and machine and deep learning.
