- 2005.12 – present, Senior Plant Nematologist, California Department of Food and Agriculture, Plant Pest Diagnostics Center, Sacramento, CA
- 1999.6 – 2005.12, Associate Plant Nematologist, California Department of Food and Agriculture, Plant Pest Diagnostics Center, Sacramento, CA
- 1998.1 – 1999.6, Post-Doctoral Research Associate, Department of Plant Pathology and Physiology, Clemson University, Clemson, SC.
- 1997.1 – 1997.12, Post-Doctoral Research Associate, Department of Plant Pathology, University of California, Riverside, CA.
- Nematode Diagnostics and Research
Specializes in quarantine and regulatory nematology. Performs highly specialized and routine taxonomic identification of plant-parasitic nematodes; and confirms regulatory pest identifications made by colleagues and others as required. Conducts research as needed to develop new nematode recovery diagnostics, including molecular-biological assays for supplementary identification, or preservation methods.
- In-charge of laboratory diagnostics for nematode surveys
Directs and coordinates laboratory diagnostic activities associated with pest detection and other nematode surveys and projects such as the annual Statewide Nematode Survey. Responsible for providing training to state, county, and other regulatory officials involved in sampling for nematode surveys. Works with CDFA, USDA, Counties, Universities, and other agencies to decide the depth and breadth of survey activity such as geographical regions, target crops, and target nematodes for which to survey. Recruits, hires, and supervises temporary employees to work on survey sample processing.
- Scientific consultation and collaboration
Assigns appropriate pest ratings to nematodes identified; makes recommendations of pest ratings for intercepted or newly discovered nematode pests; reviews permit application security and other provisions. Provides program development pest risk mitigation, other consultations and expertise to Department Staff, county agricultural commissioners, the University of California, and the United States Department of Agriculture.
- Evaluation & Application of Applied Research Methods
Develops quality standards. Maintains and monitors these standards for laboratory extraction and identification methods. Evaluates laboratory operations. Participates in program development. Designs, develops and applies new methods to laboratory operations, including molecular DNA diagnostics. Evaluates applied research and maintains literature which may have application to the operations of the Nematology laboratory
Participates in the jointly sponsored University of California and the Department annual nematology conference. Maintains and upgrades a nematology program web site on the Department internet and intranet home page.
