Prakash Kumar Jha joined UC ANR as an assistant project scientist on Nov. 1 and is responsible for developing decision support tools that help growers understand and minimize climate risks, specifically CalAgroClimate.
Prior to coming to California, he worked as a postdoctoral fellow for over five years in Italy, Spain and Colombia. Jha is eager to understand what California's climate will look like in the next five to 10 years. Currently, he is working with climate prediction systems to determine future weather conditions, which growers can use to prepare for situations like low versus high chill hours, shortage of irrigation water and high temperature stress in plants.
Jha recognizes that areas currently used for agriculture might not be suitable for some crops a couple of years from now. For example, Jha is identifying which geographical areas growers should invest in while considering factors such as regulations limiting water use. His work will help growers consider the long-term implications of the decisions they make today.
Before earning a Ph.D. in science management of climate change from the University of Venice Ca' Foscari, Italy, he completed two master's degrees – one in climate change adaptation from the University of the Sunshine Coast, Australia, and another in sociology from Tribhuvan University in Nepal.
Originally from Nepal, Jha is excited about the diversity of crops the California offers. “I'm looking forward to expanding my knowledge, especially in tomatoes, cottons, almonds and pistachios,” he said.
Jha is based at the UC Merced-Sierra Nevada Research Institute and can be reached at email@example.com.
Fatemeh Khodadadi joined UC Riverside in October as an assistant professor of extension in the Department of Plant Pathology. She brings expertise in fungal and bacterial diseases of fruit and nut trees and an increasing interest in subtropical plant diseases caused by a variety of plant pathogens.
Khodadadi's research focuses on plant pathogens and disease management strategies for subtropical trees, especially citrus and avocado. She studies identification, characterization and development of molecular methods to detect fungal, bacterial and viral diseases affecting citrus and avocado, including but not limited to avocado branch canker and dieback caused by Botryosphaeria species, phytophthora root rot, sweet orange scab caused by Elsinöe australis, avocado sunblotch viroid and other problematic pathogens on citrus and avocado in California. She also studies the citrus and avocado defense responses to pathogens and the efficacy of fungicides and bactericides.
Before joining UC Cooperative Extension, she held postdoctoral fellowships at Cornell University and Virginia Tech conducting research in bacteriology, mycology, genomics, plant pathology and plant disease management focusing on Colletotrichum species (bitter rot of apple), Erwinia amylovora (fire blight), and Diplocarpon coronaria (apple leaf and fruit blotch).
She identified, described and characterized for the first time a new Colletotrichum species that causes apple bitter rot and belongs to the C. gloeosporioides species complex. Her team named it C. noveboracense.
Khodadadi earned her M.S. and Ph.D. at Shahid Bahonar University of Kerman, Iran. For her M.S., she studied aflatoxin-producing fungi contaminating pistachio. In her Ph.D. research, partly conducted at UC Davis, she studied the interaction between walnut and bacterial blight disease caused by Xanthomonas arboricola pv. juglandis (Xaj).
Khodadadi is based in the UC Riverside Department of Microbiology & Plant Pathology and can be reached at firstname.lastname@example.org. She will be posting about her research at https://subtropicalplantpathology.com/category/blog-posts/.
Alec Dompka began with UC ANR on Oct. 20 as a rural communities economic development advisor. He will serve as technical support for economic development projects in Del Norte, Humboldt and Trinity counties.
Dompka said he aims to help local communities by working with government entities and private businesses to coordinate and facilitate beneficial projects.
“In this position, I hope to engage with people in the counties to tie them more closely with planning their economic development,” Dompka said. “I hope to show that economic development in rural communities can be locally led and directed, inclusive and effective.”
By applying technical knowledge and science-based expertise to these projects, Dompka said he also hopes to “generate research that pushes forward our understanding of what economic development looks like for rural communities.”
Born and raised in Raleigh, North Carolina, Dompka earned a bachelor's degree from North Carolina State, double-majoring in political science and economics. He also holds an M.A. in agricultural and natural resources economics from NC State.

Kirsten Pearsons began working as a UC Cooperative Extension integrated pest management entomology advisor for Monterey, Santa Cruz and San Benito counties on Nov. 7. This is a new role for Pearsons, who joined UC ANR in March as a small farms advisor in San Luis Obispo County.
Pearsons focuses on insect-related concerns on the Central Coast, such as impatiens necrotic spot virus (INSV), a disease transmitted to lettuce by thrips, and identifying possible solutions. In collaboration with USDA scientists and her UC colleagues, Pearsons is researching the biology and ecology of the thrips populations that vector INSV to identify existing tools and new strategies that can help growers manage thrips and INSV.
Though her research focuses on lettuce and cole crops, Pearsons also supports berry growers and other specialty crop producers in the region with large-scale producers and agricultural pest control advisers as current clients.
Pearsons earned a bachelor's in environmental toxicology from UC Davis and a Ph.D. in entomology from Pennsylvania State University, studying how pest management strategies adopted in field crop systems affect non-target soil invertebrates.
During her undergraduate studies at UC Davis, Pearsons was curious to know what alternatives existed for broad-spectrum pesticides.
“Funny enough, I took my first entomology class just to get a basic idea of insect biology, because a lot of what I was learning in my toxicology courses had to do with insecticides,” she said. “The staff and the other students in the entomology department were so awesome that it didn't take much for me to completely fall for the subject.”
Prior to UC ANR, Pearsons worked for the Rodale Institute, an organic research institute in Pennsylvania.
Pearsons is based out of the UCCE Monterey Bay County office and can be reached at firstname.lastname@example.org.
Cuong “Jimmy” Nguyen joined UC Cooperative Extension on Nov. 1 as an assistant food safety and organic production area advisor for Imperial and Riverside counties.
“Organic produce has a shorter shelf life and is more susceptible to outbreaks, recalls and foodborne illness due to the lack of chemical sanitizers and fungicides,” Nguyen said. “Therefore, my future research agenda will continue the focus on improving the quality and safety of organic produce commodities by developing alternatives to chemical fumigations/fungicides, as well as organic pest management without the use of chemical sanitizer or pesticide.”
While earning his Ph.D. in food science at UC Davis, Nguyen developed two novel sanitizing platforms for surface decontamination and liquid systems disinfection. The two systems involve the newly discovered synergistic disinfection effect between natural antimicrobials and UV-A light treatment or ultrasound treatment.
“I am also interested in rapid detection methods using bacteriophage targeting foodborne microbes, and microscopic detection of bacterial microcolonies for early screening and prevention of foodborne outbreaks,” he said.
Nguyen earned a master's degree at Tokyo University of Agriculture in Japan, where he studied sensory and food safety quality of meat, and a bachelor's degree in agriculture at Nong Lam University in Vietnam, where he studied postharvest technologies for food and vegetable commodities. He is fluent in English, Japanese and Vietnamese.
Nguyen is based in Holtville and can be reached at (442) 265-7700 and
Yu-Chen Wang joined UC Cooperative Extension Oct. 3 as a plant pathology advisor for Santa Cruz, Monterey and San Benito counties.
“Vegetable and berry are the major crops I work on currently,” said Wang, who will be working with a wide range of crops and different cropping systems on the Central Coast. “So far, I have been contacted by a wide range of growers – including (those who grow) lettuce, broccoli, pepper, celery, bean, apple, strawberry and blackberry – about their disease problems. I am passionate about providing insight to help the community on their disease problems.”
“The lettuce industry here is suffering from impatiens necrotic spot virus (INSV) vectored by Western flower thrip along with soilborne diseases,” she said. Lettuce growers in the Salinas Valley lost an estimated $50 million to $100 million last year and a lettuce supply shortage occurred. Working alongside fellow advisors, UC specialists and industry partners, Wang will be seeking long-term solutions for the industry.
Prior to becoming a UCCE advisor, Wang worked at AVRDC-World Vegetable Center, for a vegetable seed company, and at UC Kearney Agricultural Research and Extension Center on research and development.
Wang, a native of Taipei, Taiwan, earned her B.S. and M.S. in horticultural and crop science at National Taiwan University. She earned a second M.S. in plant protection from California Polytechnic State University, San Luis Obispo.
“The idea of farmers feeding the world and awareness of crop loss by pests motivated me to pursue a career in agriculture and plant protection,” she said. “During my M.S. at Cal Poly, I worked closely with the California strawberry growers on industry-oriented research. I look forward to extending my study to vegetable and berry crops and serving the farming community.”
Wang is based in Watsonville and can be reached at email@example.com and (831) 201-9689.
Ashley Hooper joined UC ANR on Sept. 1 as the UC Cooperative Extension urban community resiliency advisor in Los Angeles County, a brand-new position. In her role, Hooper is tasked with working with communities who have historically been disadvantaged due to inequitable systems and/or policies.
In collaboration with the community, Hooper will lead efforts focused on building resilience and adaptive capacity. This could look like increasing the community's access to capital, green space, transportation, nutritious food or education.
She already has leveraged data, collected by different organizations, to conduct a content analysis of needs assessments across dimensions of community resilience, such as access to parks and healthcare. Then, as next steps, she will prioritize interviews and field observations.
During her master's program, Hooper worked as a research assistant for the Bureau of Business and Economic Research, where she led interviews with community members facing or trying to counter various inequities like limited access to broadband, housing and health care. For her Ph.D. dissertation, she focused on identifying barriers to and opportunities for resilient food systems in Los Angeles County.
After attending the California Economic Summit in October, Hooper shared her excitement for the prospect of using the arts in building community resilience.
“I went to a creative-economy working group session, and I was reminded of how much the arts and cultural community has to offer in the process of building adaptive capacity in communities,” she said.
Hooper earned a Ph.D. in urban and environmental planning and policy from UC Irvine. She earned a bachelor's degree in psychology and a master's degree in water resources with a concentration in policy and management from the University of New Mexico.
Hooper is based out of the UCCE office in Los Angeles County and can be reached at firstname.lastname@example.org.
Joanna Solins joined UC ANR on Oct. 3 as a UC Cooperative Extension environmental horticulture advisor for Sacramento, Solano and Yolo counties.
Solins will focus on research and outreach related to urban plants, landscaping and climate change, while building relationships with county and municipal governments, nonprofits, landscape and tree care professionals, nursery growers and utilities, among others. She also will support the UC Master Gardener coordinators in her assigned counties, collaborating to extend knowledge and resources to community members.
“My core goals are to improve the climate suitability and ecological performance of urban landscaping and promote the equitable distribution of benefits from urban plants,” Solins said.
After attaining a bachelor's degree in environmental studies at Vassar College, Solins began her career leading outreach education programs for the New England Aquarium and writing for educational publishers. She also worked in communications at the Coral Reef Alliance in San Francisco before starting graduate school at UC Davis, which culminated in a master's in geography and Ph.D. in ecology.
Solins' research at UC Davis combined field studies and geographic information system analysis to investigate plant communities, tree canopy and soils along urban creeks in the Sacramento area. She also carried out postdoctoral research on green stormwater infrastructure, urban forest composition, and the water demand of urban vegetation across California, and contributed to projects examining residential landscaping and urban heat in Sacramento.
Solins is based in Sacramento and can be reached at email@example.com or (916) 875-2409.
Stephanie Mar joined UC Cooperative Extension on Oct. 3 as the assistant organic materials management advisor serving Los Angeles, Orange and San Diego counties. Mar is responsible for investigating ways to divert organic wastes from landfills to alternative end markets, such as circular food economies, composting and wastewater reclamation.
“To me, waste doesn't have an end life, just a next life,” said Mar. “A lot of people don't know what happens to their waste after the garbage truck comes or they flush a toilet, so a part of my job is to understand what we are wasting and what happens to it.”
Mar attended the University of North Carolina at Chapel Hill where she earned a master's degree in public health focused on environmental science and engineering, and a master's degree in city and regional planning focused on land use and environmental planning. She also has a bachelor's degree in public health from UC Berkeley.
Much of Mar's professional experience, like her time working for the City of Berkeley, is centered on community outreach and policy development, two strengths that she believes will serve her well in this new role.
Previously, Mar worked as a public health analyst for UC San Francisco and as a social research analyst with the North Carolina Department of Health and Human Services too. Both of which strengthened her understanding of policy and program development, implementation, and monitoring and evaluation.
“Research gives us a lot of information, but then there's a need for translation from what we know to what it actually means,” she said. “There are a lot of people doing different things [to manage their waste], so there's a need for coordination and dispersal of information."
Mar's background in policy development is something she'll rely on to operationalize the research being done by herself and her colleagues.
Behavioral change is one of Mar's anticipated challenges in this role. Even if research and policy efforts yield successful results, encouraging the community to adapt can be an uphill battle.
“Sorting trash, for example, is more of a mental burden than a physical one,” she explained. “We know what the research says and what we need to do, it's just about developing the market to make it happen.”
Mar is based out of Irvine at the South Coast Research and Extension Center and can be reached at firstname.lastname@example.org.
Kristin Dobbin has joined UC ANR and the Department of Environmental Science, Policy, and Management at UC Berkeley as a UC Cooperative Extension specialist focused on water justice policy and planning.
