Mr. Picard has approximately 14 years of experience at a global contract research organization (CRO). He has broad experience in ecotoxicology and has served as study director on numerous studies with a primary focus on sediment, pollinator, and non-target terrestrial plant testing. Mr. Picard held leadership roles in his tenure at the global CRO including that of the technical leader for the terrestrial ecotoxicology group. He is knowledgeable with regulatory guidelines (e.g. USEPA, OECD, PMRA and JMAFF) as well as all associated Good Laboratory Practice Standards. He has directed and managed studies in support of product registrations for the pesticide (conventional and biopesticides), pharmaceutical, and industrial chemical sectors.

Mr. Picard has worked with multiple task forces and working groups that include members of industry (e.g., registrants), regulatory authorities, and the academic communities. These groups were instrumental in streamlining and validating testing guidelines such as those for chronic sediment testing in the US. He has also been heavily involved in improving various honeybee laboratory testing methods including revising the methods to assess the effects of biopesticides. Mr. Picard is an active member of the Society of Environmental Toxicology and Chemistry and participates in several interest groups (Plant, Sediment and Pharmaceutical Interest Groups) within the organization.

Mr. Picard’s current responsibilities include evaluating ecotoxicology data, placing and monitoring studies and conducting ecological risk assessments in accordance with EPA regulations.

Project Experience

Acted as the ecotoxicology lead for a new pesticide active ingredient registration in both US and Canada (NAFTA Joint Review submission).

Authored white paper related to observations of remaining diet in larval honeybee acute studies and regurgitation in adult honeybee studies with regards to study acceptability.

Worked with both regulators and registrants to improve non-guideline test methods with benthic marine amphipods.

Acted as study director and program manager on large sediment testing program consisting of several complex acute and chronic studies. Assessed toxicity of highly adsorptive materials using several sediment types with varying organic carbon contents.

Provided technical oversight for multiple types of studies including sediment, non-target plant, pollinator, aquatic plant, non-target arthropod, and fit for purpose studies to address specific regulatory issues.

Led staff of scientists in designing efficient laboratory diet trials for inclusion of low solubility materials into honeybee diets. Worked both internally and with industry groups in validating alternative methods of suspending materials in adult bee sucrose diets.

Assisted in addressing deficiencies in studies to be used for pesticide risk assessment purposes.

Monitored several ecotoxicity studies at CRO to support registration of a biopesticide.
