Managing Scientist
Chemical Regulation & Food Safety
  • District of Columbia

Mr. Tucker has over 20 years of consulting experience addressing EPA-related regulatory issues for clients. His areas of expertise include conducting registerability and data gap evaluations for new compounds, FIFRA and FFDCA regulatory issues concerning new and existing registrations for conventional pesticides, biopesticides, and products of biotechnology, addressing challenging residue chemistry issues, and data compensation matters. Other areas of expertise include managing and conducting human health exposure and risk assessments for submission to the EPA, identifying and developing mitigation measures, and developing corresponding regulatory strategies.

Mr. Tucker also has experience with the regulatory and technical requirements for import tolerances. In addition, he has experience with electronic data submission issues (USEPA and Canada PMRA) and with preparing and assembling submissions for pesticides submitted under the Global Joint Review (GJR) process. He has also has worked on specific pesticide related databases including the USDA’s Pesticide Data Program, the FDA’s Pesticide Monitoring Database, the FDA’s Total Diet Study Database, and the state of California’s Pesticide Monitoring Database and Pesticide Use/Usage Database. Additionally, Mr. Tucker has extensive experience in conducting training sessions for the Dietary Exposure Evaluation Model (DEEM™) for both government (EPA, USDA, and Health Canada) and private industry clients.

Project Experience

Led a project team that compiled electronic data submissions for the EPA and PMRA for a new active ingredient as part of a Global Joint Review. Frequently communicated with both EPA and PMRA staff concerning the electronic submissions and addressed issues as they arose. Further, as part of a submission to APVMA, led a team that designed an Adobe-based file that allowed for easy navigation throughout the electronic submission.

Worked on numerous projects related to complex client issues in the area of residue chemistry. As part of these projects, reviewed numerous field protocols and studies, interfaced with contract laboratories, contacted EPA concerning issues, and gave client expert advice on strategic next steps.

Conducted several registerability and data gap analyses for specific compounds. These evaluations included leading multi-disciplinary regulatory and technical teams in the review of the regulatory status and the toxicological, ecotoxicological, and environmental fate profile of the compounds.

Key member of several project teams that advised clients on the development of global field trial programs in support of import tolerances for both the US and Canada. This involved addressing regulatory issues and evaluating global trade patterns in order to determine the number and location of needed field trials.

Provided data compensation support for numerous pesticide products in a variety of circumstances. Performed in-depth expert evaluations and cost estimates/reconstructions of data in support of clients’ data compensation cases. Provided expert reports as required.

Worked on a number of projects related to submission support for PMRA submissions (new active ingredient registrations, new end-use product registrations, and import tolerances). This involved working closely with the registrant and PMRA staff to address issues.

Assisted in the execution of multi-year GLP market basket surveys. Designed approaches for the management and compilation of large volumes of raw data in accordance with GLP procedures.

Conducted or served as an advisor on many assessments of dietary exposures to pesticides in support of registration and re-registration activities in the U.S and Canada.

Worked on many projects related to approval of Experimental Use Permits (EUPs) for plant-incorporated protectant products. Worked with the states to make sure that the EUPs were granted and that all reporting and other follow-up requirements were met.
