Axelson is based at the UC Berkeley campus and can be reached at (510) 642-8459 and email@example.com. Follow her on Twitter @DisturbedDendro.
Haghverdi joins UCCE as urban water specialist
Amir Haghverdi joined UCCE on July 1 as a UC Cooperative Extension specialist in the Department of Environmental Sciences at UC Riverside. His research focuses on integrated urban water management.
Prior to joining UCCE, Haghverdi had been an assistant professor in the Department of Biological Systems Engineering at University of Nebraska-Lincoln, performing research and extension on irrigation and water management, since July 2015.
Haghverdi earned his B.S. in irrigation engineering from University of Tehran, Iran, an M.S. in agricultural engineering - irrigation and drainage from Bu-Ali Sina University, Iran, a Ph.D. in irrigation and drainage engineering from Ferdowsi University of Mashhad, Iran, and a Ph.D. in biosystems engineering from University of Tennessee-Knoxville.
Haghverdi can be reached at (951) 827-4774 and firstname.lastname@example.org.
Saitone named ag economics specialist
Prior to joining UCCE, Saitone had been a project scientist for ARE since July 2015. Before returning to UC Davis, she worked for OnPoint Analytics, an economic consulting firm in the Bay Area, where she conducted research on a wide variety of agricultural industries including meatpacking, dairy, eggs, broilers and sugar beets.
Saitone earned her B.A. in economics at Sonoma State University and her M.S. and Ph.D. in agricultural and resource economics at UC Davis.
Bautista named 4-H STEM coordinator
Jessica Bautista joined ANR on July 5 as the 4-H Science, Technology, Engineering & Mathematics (STEM) academic coordinator.
Prior to joining ANR, Bautista was a graduate research assistant in the Department of Botany and Plant Sciences at UC Riverside. Bautista's area of research interest focused on molecular biology and genetics in plant developmental biology.
As a native Californian and a first-generation student born to Mexican migrant parents, Bautista speaks Spanish and has fostered various methods to make her research accessible and advocate for STEM career paths for underrepresented communities. In 2012, Bautista co-founded UCR's Plant Discovery Day in the Department of Botany and Plant Sciences. This annual outreach event is filled with interactive science demonstrations for elementary school students in the community. She has also presented her research and discussed her career path annually since 2013 at workshops geared towards teaching and empowering young Latina women to pursue higher education and various career options.
Bautista completed a B.S. in biotechnology (chemistry minor) from California State University Northridge and a Ph.D. in plant biology from UC Riverside.
Pourreza wins international prize for HLB detection
Newly appointed UC Cooperative Extension agricultural engineering advisor Alireza Pourreza has been awarded the 2016 Giuseppe Pellizzi Prize by the Club of Bologna, an honor presented every other year to the best doctoral dissertations focused on agricultural machinery and mechanization. The Club of Bologna is a world taskforce on strategies for the development of agricultural mechanization.
Pourreza, who earned his Ph.D. at the University of Florida in 2014, worked on early detection of Huanglongbing disease of citrus. Huanglongbing, an incurable disease that is spread by Asian citrus psyllid, has seriously impacted citrus production in Florida. The disease has been found in commercial and residential sites in all counties with commercial citrus.
Early detection allows growers to remove infected trees before the disease can spread to healthy trees. Currently HLB infection is confirmed when leaves with yellowing blotches are submitted for PCR testing, which is expensive and time-consuming. However, the yellowing can be also symptomatic of other conditions, such as nutrient deficiency.
"We discovered we could see the symptoms of Huanglongbing using a camera, a set of cross-polarizers and narrowband lighting before it is visible to the human eye," said Pourreza, who is based at the UC Kearney Agricultural Research and Extension Center in Parlier.
He said the yellow blotches on HLB-infected leaves are caused by starch accumulation.
"If we could detect abnormal levels of starch in the leaf, we could tell it is affected with HLB," Pourreza said. "Starch showed the ability to rotate the polarization plane of light. We used this optical characteristic to develop the sensing methodology."
Pourreza said the team has patented the technique and is working on developing a commercial product. He is seeking funding to continue the research in California, where, to date, HLB has only been detected in isolated Los Angeles neighborhoods. Asian citrus psyllid is found in important California commercial citrus production regions from the Mexican border to as far north as Placer County.
4-H Youth Development team wins national diversity award
4-H Youth Development advisors Dorina Espinoza, Russell Hill, Fe Moncloa and Keith Nathaniel and 4-H associate director Shannon Horrillo have won the National Extension Diversity Award for systematically enhancing the intercultural competency of 4-H personnel and others in California.
The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-grant Universities (APLU), honors the team for creating and using Intercultural Development Inventory© to shift organizational culture. This shift includes mutual respect, acceptance, teamwork and productivity among diverse people.
To meet the needs of a culturally and ethnically diverse youth population in California, they created a professional-development intervention for 4-H academics and staff. The Intercultural Development Inventory© is a cross-culturally generalizable, valid and reliable assessment of intercultural competence. Calling themselves the Intercultural Development Inventory Qualified Administrators, they applied the strategy over three years, providing 176 hours of intercultural communication feedback sessions, learning communities and regional conferences to enhance the intercultural competence of 65 4-H personnel.
Evaluations demonstrated that after the intervention UC 4-H Youth Development Program personnel had acquired skills and characteristics to become more culturally competent. The program has moved from focusing on similarities across diverse people that can mask deeper recognition of cultural differences to recognizing the complexity of dimensions of diversity.
The action plan and resulting positive change provides the potential to improve hiring and professional development nationwide by replication in other states. A summary of California's IDI professional development activities can be found in the National 4-H Latino Youth Outreach: Best Practices Toolkit, Professional Development.
