Tracking contaminants:
From exposure to biological impact
Our Group

Todd Harris
Research Associate
My research into dietary lipids, nutrition and health began with an interest in an enzyme that metabolizes oxidized lipids, soluble epoxide hydrolase (PhD with Bruce Hammock, UC). My research in Amy's lab continues to explore the impact of diet-derived lipids on cellular processes.

Amelia Williams
Research Assistant
Amelia recently completed her MSc in Chemistry at Carleton University, with an overarching interest in developing trace-level PFAS LC-MS/MS methods applied to consumer products and indoor environments.

Jillian Rohonczy
Postdoctoral Fellow
Jillian completed her PhD in Chemical and Environmental Toxicology at Carleton University. Her research examined the effects of environmental contaminants on fish and amphibians, focusing on per- and polyfluoroalkyl substances (PFAS). Building on her expertise in PFAS effects in aquatic organisms, Jillian is exploring PFAS transformation by gut microbiota. Outside the lab, Jillian enjoys riding horses, scuba diving, reading, and crafting.

Amanda Sakyi
PhD Student
Amanda completed her BScH in Biochemistry at Carleton and began her PhD specializing in Chemical and Environmental Toxicology. She aspires to become a forensic toxicologist. Amanda is exploring the bioactivation and oxidative stress response of toxicants within the nematode C. elegans. Outside of the lab, Amanda spends her free time dancing or playing her clarinet, cooking, and hiking.

Genevieve Hache
PhD Student
Geneviève completed her BScH in Biochemistry at the University of Ottawa. Motivated by her interdisciplinary interest in toxicology and microbiology, she’s currently studying the effects of PFAS microbial cycling in model systems. Geneviève enjoys nerding out through tabletop games or video games, working out at a rock climbing gym or a squash court, and jamming out with the National Capital Concert Band.

Caitlyn Hsiung
MSc Student
Caitlyn completed her BScH in Biomedical Toxicology (co-op) at the University of Guelph. Inspired by her previous co-op work term placements, she is currently pursuing an MSc, studying the effects and bioaccumulation of PFAS during the early development of fish. Outside of the lab, Caitlyn enjoys travelling, photography, painting, and discovering new restaurants to try in Ottawa.

Emily Blokland
MSc Student
Emily completed her BScH in Environmental Science with a concentration in chemistry at Carleton University. She is currently working on her MSc in Chemistry with a specialization in Chemical and Environmental Toxicology, studying PFAS on indoor particulate matter. Outside the lab, Emily enjoys reading, hiking, and baking.
