Colleen Priest is an Environmental Risk Analyst with Intrinsik Environmental Sciences (US) Inc.  She has helped conduct numerous pesticide risk assessments for the purposes of registration and re-registration in Canada and the United States, as well as individual (e.g., Indiana bat) and national endangered species assessments for many pesticide active ingredients. Pesticides have included imidacloprid, clothianidin, 2,4-D, carbofuran, carbosulfan, chlorpyrifos, dicamba, dimethoate, glufosinate, malathion, and others. Recently, Colleen conducted a screening-level ecological risk assessment to evaluate the effects of clothianidin to aquatic invertebrates in Canada and the United States. Colleen has also been instrumental in helping to develop criteria for a national endangered species assessment framework and applying the criteria to endangered species assessments for a selection of organophosphates pesticides.

In this position, she conducted oil-related research on behalf of the Trustees on the Deepwater Horizon Oil Spill Case.

In 2011, Colleen completed a Master’s of Science degree, which evaluated the acute and chronic toxicities of chemically dispersed crude oil to Atlantic and Pacific herring embryos.
