Philip Waisen (Ph.D.)
Dr. Philip Waisen is currently a Vegetable Crops Advisor at the University of California Cooperative Extension (UCCE). He started on January 10, 2022, and works out of the Indio Office in Riverside with responsibilities both in Riverside and Imperial counties. Prior to joining UCCE, Philip was a postdoctoral researcher at the University of Hawaii at Manoa, where he worked on Western SARE-funded research projects on nematode and soil health management in agroecosystems (tomato, peppers, cucurbits, asparagus, banana, brassicas). He also taught a graduate-level Plant Nematology course for a semester while as a postdoctoral researcher. For the whole of 2021, Philip was attached with his undergraduate school, the Papua New Guinea University of Technology as a part-time lecturer teaching Plant Pathology, Research Methods, and Horticultural Sciences courses.
Here at UCCE, Philip is developing Research and Extension Programs focused on Pest and Disease Management, Soil Health and Fertility Management, and Cover Crops and Insectary Plants in Low Desert Vegetable Cropping Systems.
