I am currently on the faculty in the Department of Ecology and Evolutionary Biology at University of Toronto.

Previously, I was a David H. Smith Postdoctoral Fellow at the Aquatic Health Program at the University of California, Davis. I received my PhD in a joint program with San Diego State University and UC Davis in Ecology and was advised primarily by Swee Teh and Eunha Hoh. For more about me, please download my CV.

Current Lab Members:

Alice (Xia) Zhu – MSc Student

Alice is thrilled to be working on the issue of microplastics. Alice’s research involves collaborating with the San Francisco Estuary Institute to monitor microplastics in the San Francisco Bay, to model the sources of microplastics entering the Bay, and to propose policies to help protect the Bay from further pollution.

Clara Thaysen – MSc Student

Clara was an undergraduate student in our lab who majored in Ecology and Evolutionary Biology and Earth Sciences. She is now a MSc student researching the fate of microplastics in aquatic food webs. Her past research in our lab has investigated the potential leaching and toxicity of styrenes and other volatile chemicals from food packaging into food products. This project was in collaboration with 5 Gyres and MOECC. Clara is also continuing and finishing a project investigating plastic ingestion in seagulls and examining the fate of flame retardants to and from plastic debris in the gulls. This project is in collaboration with Miriam Diamond and Jonathan Verreault.

Rachel Giles – MSc Student

Rachel is excited to be studying urban runoff in Toronto streams. This project, in collaboration with Toronto and Region Conservation Authority, Environment and Climate Change Canada, and the Sinton Lab will investigate how benthic macroinvertebrate communities respond to salt-laden urban runoff during the winter months. This multi-stressor, community-focused approach will complement current research that recognizes tire dust, road salts, polycyclic aromatic hydrocarbons, and metals as contaminants with harmful ecological effects. 

Kennedy Bucci – PhD Student

Kennedy’s research focusses on the biological and ecological effects of microplastic pollution in freshwater environments. She is currently collaborating with the Ministry of Environment and Climate Change (MOECC), studying the chemical and physical effects of various microplastics on freshwater fish. Her research goals include investigating the ecosystem-level effects of microplastic pollution using experimental mesocosms.

Lisa Erdle – PhD Student

Lisa researches the effects of microplastics on fish in the Great Lakes. In her work, Lisa collaborates with the Ministry of the Environment and Climate Change (MOECC) as well as Environment and Climate Change Canada (ECCC) to better understand how microfibers – one of the most common types of microplastics – impacts fish through physical and chemical processes.

Joel Kim – PhD Student

Joel has an interest in anthropogenic contaminants, their effects on freshwater ecosystems, and revolving consequences to humans. In the Rochman Lab, his research involves looking at microplastics and associated chemical contaminants in freshwater fish caught for human consumption. This research is in collaboration with Paul Helm, Tim Ksrul, and Satyendra Bhavsar at the Ministry of the Environment and Climate Change.

Bonnie Hamilton – PhD Student

Bonnie received her B.S. with honors in Environmental Health Science from Alma College (Michigan). She is currently a PhD student researching the ecotoxicity of microplastics and their relationship with other anthropogenic stressors in Arctic ecosystems. Her work is in collaboration with local communities, Environment and Climate Change Canada and NGOs.  Additionally, she is working with the Monterey Bay Aquarium Research Institute on a collaborative project evaluating the movement of microplastic and chemical pollutants in the Monterey Bay pelagic food web.

Samantha Athey – PhD Student (Rochman and Diamond Group)

Sam received her B.S. with honors and M.Sc. in Marine Science from the University of North Carolina Wilmington, where she conducted research on microplastic ingestion in marine species. She is currently completing her Ph.D. at the University of Toronto, studying microfiber and chemical loss from clothing in the context of Great Lake ecosystems. ​Learn more about microfiber pollution and her research through Sam’s blog: the Microfiber Pollution Project!

Dr. Anna Kolomijeca – Postdoc (Rochman and Sinton Group)

AnnaStarfish.JPG

Anna holds an Engineering Degree in Chemical Technology (2010) from Riga Technical University (Latvija) and a PhD in Physics from Technical University Berlin (Germany). Anna has vast international work experience, which includes an Erasmus internship in France at MSC (Matière et Systèmes Complexes), a scholarship in Norway at the Norwegian University of Science and Technology (NTNU), a secondment in France at IFREMER oceanographic center, a research cruise in the Arctic, a short placement at Vree University Amsterdam and one postdoc in the Autonomous University of Barcelona. Anna specializes in environmental sensing (optical and remote sensing). Currently she is a postdoctoral researcher at the University of Toronto, where she works on problems related to environmental pollution and climate change.

Jelena Grbic – Research Assistant

Jelena has her Master’s degree in Spatial Analysis from Ryerson. We have the pleasure of working with Jelena on research projects that measure how best to identify microplastics in complex matrices and use spatial analyses to identify sources and sinks of microplastics in Lake Ontario. This research is also in collaboration with Paul Helm at the Ministry of the Environment and Climate Change as well as the Smith Fellowship.

Keenan Munno – Lab Manager & Research Assistant

Keenan is a recent M.Sc. Ecology graduate from the University of Toronto with a particular interest in the fate and effects of microplastics in fish. Her work focused on method development, as well as microplastic ingestion and retention in freshwater fish from the Great Lakes. She obtained her undergraduate degree from Queen’s University in Biology, with a thesis in freshwater oil spill toxicology. She is continuing to pursue her interests in identifying and quantifying microplastics through her work as a Research Associate and Lab Manager in the Rochman lab.

Aimee Huntington – Undergraduate Research Assistant

Aimee is in her last year of her Honours Bachelor of Science, pursuing a double major in Biodiversity and Conservation Biology with Sociology. She is currently analyzing samples from the Eastern Canadian Artic, the first large-scale project to investigate the distribution of microplastics in this region. She hopes to explore the impact of microplastics on Arctic organisms next. Aimee is also passionate about studying anthropogenic stressors on biodiversity from an interdisciplinary approach.
