About Us

About TriCal Diagnostics:

TriCal Diagnostics is a team of highly experienced plant pathology diagnosticians that has extensive knowledge of practical field plant pathology, microbiological and molecular identification techniques, plant pathology research, and production agriculture and horticulture. The first step in managing plant diseases is identifying the cause of such problems. Therefore, effective disease management relies on careful diagnosis. TriCal Diagnostics offers disease and plant problem identification services to growers, field personnel, pest control advisors, homeowners, the general public, and others throughout and beyond California. TriCal Diagnostics is a team that values service and provides accurate and timely diagnoses to clientele.

Dr. Hanane Stanghellini

Manager Dr. Hanane Stanghellini received her Ph. D. in Plant Pathology and Soil Ecosystems from the University of Bonn, Germany. She has over 20 years of university research and private-sector experience in custom diagnosis of fungi and bacteria, microbial community structures, molecular analysis and functional genomics of nematodes, and disease resistance screening.


Dr. Kristi Sanchez
Dr. Kristi Sanchez

Senior Researcher and Nematologist Dr. Kristi Sanchez received her Ph. D. in Plant Pathology, specializing in Nematology, from the University of California, Davis. She has over a decade of combined research and field experience while working at UC Davis, the agrichemical industry, and the Plant Pest Diagnostics Center with the California Department of Food and Agriculture. Kristi’s research background includes pest management of nematodes, morphological and molecular diagnostics of plant parasitic nematodes, and the development of experimental assays for nematode studies in the lab and field. With TriCal Diagnostics Kristi will be focusing on nematode sampling, detection, identification, and quantification.


Dr. Alyssa Burkhardt
Dr. Alyssa Burkhardt

Molecular Specialist Dr. Alyssa Burkhardt received her Ph. D. in Cell and Molecular Biology from Michigan State University where she researched resistance-associated genes in cucumber in response to downy mildew infection. As a post-doc researcher at the USDA-ARS in Salinas (Frank Martin lab), Alyssa developed RPA assays to detect major strawberry pathogens (Fusarium oxysporum f. sp. fragariae, Macrophomina phaseolina, Verticillium dahliae) and a qPCR assay to quantify Macrophomina in soil samples. Alyssa has nearly a decade of experience developing and running DNA-based assays. With TriCal Diagnostics Alyssa will be focusing on molecular based diagnostics and developing and optimizing DNA-based tests for diagnostics and research.
