She uses drones to detect pest problems from the air, and to potentially distribute biological control organisms. Also, she contributes to the development of a smartphone app to optimize pesticide spray coverage, reducing overall pesticide use. Elvira obtained her Bachelor’s and Master’s degrees at Utrecht University in the Netherlands. For her PhD, which she obtained at the University of Neuchatel in Switzerland, she worked on insect pest resistance in modern corn and its wild ancestors, the teosintes. Before moving to California, she worked as a researcher at Rutgers University in New Jersey, where she evaluated the use of volatile lures to attract natural enemies in cranberry.
Norman Ellstrand: At age 4 Norm’s parents helped him match a picture of a Scarlet Tanager to a bird in the yard, starting his interest in biodiversity. In 1979 he started his first (and only) academic job at UC Riverside. He has always conducted research on plant sex, usually in the guise of applied evolutionary genetics. The topics have ranged from cherimoya identification to the evolution of invasiveness to hazards associated with the escape of engineered genes. Ellstrand has presented his research to audiences ranging from congressional staff to Cuban biotechnologists. Ellstrand’s honors include a Fulbright Fellowship to Sweden and a Guggenheim Fellowship. Bird-watching remains a passion as Norm’s “life list”inches beyond the 1100 milestone. He is married to Dr. Tracy Kahn, Givaudan Endowed Chair and Curator of UCR’s Citrus Variety Collection. Their son, Nathan, is at Loyola University of Chicago where he is pursuing a Ph.D. in History.
Ben Faber: I frequently ask myself who, how and why I am serving. Some days I feel like a traveling salesman, a day laborer, a truck driver, a school teacher, a scientist, a bureaucrat, a psychologist, a paper pusher, a Lone Ranger, a team player, an orator, a writer, a — you get the idea. No one day is exactly like another when you are a farm advisor (notice we spell it with an “or”, not an “er”, just to be different), and I find myself playing very different roles from day to day. Being an academic with the University of California affords that rare opportunity called academic freedom – freedom to do what we find interesting and potentially profitable to society, individuals, and the environment. This freedom, though, comes with the expectations that we will maintain high academic standards, such as publish research that is recognized by our peers. Peer-recognition does not seem too important when I have just been able to solve a grower’s irrigation problem, just hauled 800 pounds of sulfur 150 miles to start a research project, or just taught a 4-H course in soils. It really only adds to the schizophrenia. My position description is for soil (that’s where most plants grow), water (that’s what most plants need), and subtropical horticulture (avocados, citrus, cherimoya, feijoa, etc.), so it basically means I need to define what I am going to work on, otherwise I would be working on everything.
Eric Focht has worked at UC Riverside with avocados since 1999 in a variety of capacities. Dr. Mary Lu Arpaia initially hired him as an extra hand for the avocado phenology project, which tracked Hass development throughout the year. He then worked on the Lamb Hass maturity project and, later, under David Stottlemyer in the re-establishment of the long running UC Avocado breeding program. In 2005, after Mr. Stottlemyer’s retirement, he took over day-to-day breeding aspects of the avocado program and has continued to try to bring this novel crop into the 21st century. In 2018, Mr. Focht went back to school at UC Riverside with the goal of attaining a doctorate in Plant Biology with a focus on Plant Breeding and Genetics, and he is currently 2 years into the program.
Raquel Folgado holds a Doctorate in Bioscience Engineering (KU Leuven, Belgium). She started her research career in Spain and she has been working in different countries in Europe before she joined The Huntington in 2014. Dr. Folgado is leading a cryopreservation program at The Huntington, which focuses on the conservation of avocado as well as wild plants including aloes, agaves, cacti, magnolias, cycads and oaks. The protocols to preserve plant germplasm in liquid nitrogen will help to ensure a long-term conservation for threatened and rare species. Methods have been optimized for many crops, but more interest is needed for wild species. Dr. Folgado has created in vitro repositories at The Huntington to preserve aloes, agaves and magnolia trees in small space and to allow propagation and distribution of the plants. Besides she is leading to create a seed bank or Cactaceae to preserve those emblematic species. Dr. Folgado serves as a reviewer for several scientific journals, and she is associated with scientific societies. She works in collaboration with researchers worldwide (Australia, Belgium, Mexico, USA, Puerto Rico, Dominican Republic).
Julie Frink: I am the Curator for the Avocado Variety Collection, University of California Research Station in Irvine, California, a 200-acre research facility. I’ve been working in the avocado collection since 1992. We started with 50 varieties and now have over 200 varieties of avocado and I have some in my yard that aren’t in the collection. The result of having an interest like this is that you end up living in a jungle. I grew up in Oregon on a wheat ranch, graduated from Whitman College in Washington with a degree in psychology and education before moving to Southern California. I was an elementary and music teacher for a number of years and taught piano for 48 years. My main interests are fruit varieties, especially avocado, and music. I’ve been a member of CRFG for many years and am a past president of the OC CRFG.
Mark Hagg: I have been teaching Animal and Veterinary Science at Cal Poly since 2010. Courses include Reproduction and Endocrinology, Beef and Dairy Cattle animal science, Pharmacology, and Bee Science. Several times per year I host at Cal Poly a workshop for beekeepers to understand the nuances of working in concert with the bees and understanding better the devastation of colony collapse disorder. Born and raised in Southern California I marvel at how different our climate is compared to anywhere else in the country. In spite of my southern California city roots I have been involved in Agriculture since high school. I grew hay, corn and gladiolas in the 1970’s and raised a dozen registered Angus cattle on land where the Brea Mall now sits. We face many challenges feeding our world and southern California is a special place where rare and new foods can survive and thrive.

Ramiro Lobo has been the Small Farm and Agricultural Economics Advisor for the University of California Cooperative Extension in San Diego County since 1997. His primary responsibility is to conduct research and educational activities to support small-scale agricultural producers in San Diego County. Ramiro’s work focuses primarily on educating small scale producers on topics related to agricultural business and risk management, new crop development and evaluation, new entry grower education, market development through agricultural tourism and direct marketing, and food and pesticide safety education. Ramiro’s field research has focused on the development and evaluation of new or specialty crops that are more water efficient and which can be viable alternatives for small and medium sized farmers to replace non-profitable crops they currently grow. These research efforts have contributed to the establishment of blueberries and pitahaya or dragon fruit as viable commercial alternatives for producers in Southern California. The acreage planted to these crops and the interest among growers continue to increase as evidenced by participation on educational activities such as the annual Pitahaya Festival & Research Field Day.
Dennis Luby grew up in Bellingham, Washington. After 8 years in the army, an RN degree and an MBA from the Universe of Cincinnati, I settled in Southern California and worked as a RN until I retired in 2014.

She is currently a postdoctoral scholar at the USDA National Clonal Germplasm Repository in Davis where she also worked prior to her PhD. Her research interests are in understanding and describing the genetic diversity of the fruit and nut tree collections, connecting crop traits to genetics, and developing improved rootstocks for walnuts, almonds, and pistachios. She along with her willing but reluctant husband and flock of chickens dream of one day having a small farm.
Jon Verdick: I grew up with all sorts of edibles: fruits, nuts, and vegetables, really from birth. I don’t ever remember not being in the garden. The love of fresh, tree-ripe fruit has been a life-long pursuit. I joined California Rare Fruit Growers (http://www.crfg.org) more than 30 years ago with 2 goals: finding Cherimoyas and Passion Fruit. That led to Sugar Cane, Bananas, Canistel, Che, Pitangas, and a whole world of other fruits; oh, and Figs. When I was a child, figs were for Newtons only, but, as a CRFG member, owning a tree became an obligation (everyone else had them). So, I acquired a couple, and wanted just a couple more good ones. Long story, short, the hunt for a couple great varieties turned into a collection of about 1000 varieties. All of the information I collected in an attempt to understand my figs eventually led to a website (why not share: http://figs4fun.com), taking tens of thousands of pictures, visiting the USDA collection at UC Davis, trading cuttings across the country, and making a lot of great fig friends. I still grow all the other stuff, including 100 varieties of bananas, but figs have truly been the most fun of all. Other pursuits have paid the bills, but gardening has always supplied the passion and the fun, in addition to great fresh food.

Don Winterstein has had a lifelong interest in plants and gardening, but he got serious after retiring from a career in seismological research in 1999, when he got access to a large (by suburban standards) utility easement area behind his backyard. This became his garden, over the Edison Company’s dead body, so to speak. Soon after, he joined the Orange County Chapter of CRFG and has been happily growing a wide variety of fruiting perennials (and veggies) in his big garden ever since.
Apart from a college course in plant physiology Don has had no formal training in horticulture but has picked up most of what he knows about the subject from hands-on experience, reading and listening. His garden soil and environment fortuitously turned out to be well suited to vegetation, so, except for watering and pruning, his many fruiting plants largely take care of themselves.
Katie Wong: MOTHER NATURE’S HELPER — I was born in Kweilin in Southwest China and lived in Hong Kong before coming to the US in 1963. I have lived in Arizona and New Hampshire before settling in California. My garden reflects the flora of the various climates I have lived in. It’s a hodgepodge of plants from Cacti & Succulents to Water Plants and Herbs and everything in between — all to attract birds, bees, butterflies and beneficial insects. My horticultural knowledge comes from training in the Master Gardeners Program and being a member of various plant societies. I have come to the realization that most of the real knowledge comes from others who have shared with me. I served several years as the CRFG-Silicon Valley Chapter newsletter editor and the Question & Answer coordinator for the Fruit Gardener Magazine. Currently, I’m dabbling in Chinese herbs. My goal is to make my front yard my pharmacy and my backyard my supermarket!
Glen Woodmansee worked his way through import restrictions to bring many of New Zealand’s delicious feijoa (pineapple guava) varieties to the U.S. for the first time. They are now producing fruit at “The Huntington’s” new collection. Glen is an amateur feijoa and video enthusiast whose popular chapter talks incorporate video clips.
