He focuses his research on the behavioral, population and evolutionary ecology of parasitoid-host and predator-prey interactions. His work has direct applications to integrated pest management and biological control in agriculture.
Rosenheim explains on his website: "I am an ecologist with broad interests, including behavioral and evolutionary ecology as well as population and community ecology. I focus on predator-prey, parasitoid-host, pathogen-host, and plant-insect interactions. My general approach is to try to ask important, fundamental questions in ecology with an eye to advancing our basic understanding and, when possible, to simultaneously make contributions to solving problems in the real world. I attempt to integrate empirical studies (observational work, manipulative experiments) with theoretical investigations (simulation and basic analytical models); I often find that I can make the best progress with my research problems by conducting a dialogue between theory and experiment. I also try to balance work in natural ecosystems and in agricultural ecosystems, where predators and parasitoids are so important as biological control agents."
Rosenheim joined the UC Davis faculty in 1990 as an assistant professor, advancing to associate professor in 1994, and full professor in 1998. He is active in the Entomological Society of America, Ecological Society of America, Society for the Study of Evolution and the American Association for the Advancement of Science.
He received his bachelor's degree in entomology and genetics from UC Davis in 1983, and his doctorate in entomology in 1987 from UC Berkeley.
The International Organization for Biological Control was established in 1956 to promote environmentally safe methods of pest and disease control in plant protection. The Global Council sponsors many international working groups and publishes a newsletter.
Undergraduate student Jessica West, Ph.D. candidate Rosanna Kwok, and research specialist Katherine “Katie” Murphy all excel in STEM, an acronym that stands for the academic disciplines of “science, technology, engineering and mathematics.”
“Undergraduates who learn cutting-edge research skills in laboratories like Dr. Chiu's set themselves apart from students who only pursue coursework for their degree,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. “Undergraduate research opportunities are what turn science students into young scientists.”
Early in their undergraduate studies, West and Murphy were accepted into the UC Davis Research Scholars Program in Insect Biology, a vigorous, multi-discipline, research and mentoring program administered by UC Davis Department of Entomology and Nematology faculty members Jay Rosenheim, Louie Yang and Chiu.
"Including this year, over the first six years that the program has operated, we have admitted 58 students, 36 of which (62%) are women," said Research Scholars Program co-administrator and professor Jay Rosenheim.
"It is asking a lot of freshmen and sophomores to jump into an intensive research experience when they are already challenged by their academic course load," Rosenheim said. "But we've been very gratified with the accomplishments of the students and their demonstrated abilities to develop the skills needed to conduct independent research. Strong effort by the students and close mentorship by campus faculty seem to be key ingredients in student success.”
Like West and Murphy, Kwok gained scientific skills and strong mentorship from Chiu, whose research interests span molecular genetics of animal behavior, circadian rhythm biology, and insect genomics. As a graduate student, Kwok won a two-year National Institute of Health fellowship in biomolecular technology.
West, who will receive her bachelor's degree in bochemistry and molecular biology June 12, is the recipient of the 2016 College of Biological Sciences Medal—only one is awarded each year. She also won an “Outstanding Citation for Research Performance.” Although not yet in graduate school, West has already published two peer-reviewed articles. In November 2015, she received the President's runner-up prize at the Entomological Society of America (ESA) meeting in Minneapolis for her talk on the seasonal biology of the spotted wing drosophila, Drosophila suzukii. This fall she will enroll in the Ph.D. program in biochemistry at Cornell University, Ithaca, N.Y. “Over her undergraduate graduate career, Jessica has compiled an impressive list of awards and prizes,” said Chiu, an assistant professor in the UC Davis Department of Entomology and Nematology.
Kwok, scheduled to graduate from UC Davis in the fall of 2016 with a Ph.D. degree in entomology, has already published six peer-reviewed papers, including one in PLOS Genetics, and has three more in preparation. As part of her requirement for her 2014-16 NIH fellowship, she will leave the Chiu lab in June 2016 to start an internship at OncoMed Pharmaceuticals, Inc. in Redwood City, CA. The internship is her last requirement before graduation from the Entomology Graduate Group.
Like West, Kwok received a President's runner-up prize (2013 ESA meeting) for her presentation on the chronotoxicity of spotted wing drosophila, working with Chiu and Professor Frank Zalom, integrated pest management specialist in the department. “I believe Rosanna will have a very successful career in the biotech industry,” Chiu said.
Murphy, who was accepted into the inaugural class for the Research Scholars Program in Insect Biology, began working in the Chiu lab her sophomore year. When she graduated from UC Davis in 2014 with a bachelor of science degree in neurobiology, physiology, and behavior, she received an “Outstanding Citation for Research Performance.” After graduation, she opted to stay in the Chiu lab to gain more research experience. “Over her career in my lab--from undergraduate research to two years of technician-- Katie has already published four peer-reviewed papers, has one currently in review, and two in preparation,” Chiu said. She is also an author on a provisional patent application for a biopesticide that the Chiu lab developed to target insect pests.
“Katie's productivity and skills are amazing,” Chiu said. “She will be leaving our lab starting June 2016 to pursue a career in metabolic engineering --she has already found a position as a research scientist in REG Life sciences, Inc. in South San Francisco.”
The three young women followed a similar path to get where they are today and strongly encourage others to pursue STEM careers.
Jessica West, who grew up in the Redding area of Northern California, spent her childhood in the small town of Shasta Lake before enrolling at UC Davis.
“I first became interested in science in high school, particularly when I took Advance Placement (AP) Biology,” West recalled. “ I was very curious and always asked a lot of questions in school. What excites me the most is that now I can ask questions that don't yet have answers, and through my research I can work to actually answer them.”
West, who will start her PhD program in biochemistry, molecular and cell biology at Cornell in the fall, says her career goal “ is to teach and conduct research at the university level.”
“I think it's important to start getting girls involved in science at a young age,” West said. “Often young girls are not encouraged to pursue their interests in STEM subjects, but I think that the culture is changing. There are programs like Girls Who Code that seek to get more girls involved in STEM fields that are traditionally male-dominated. If young girls can see that other women like them can succeed in STEM fields, they are more likely to see their goals as attainable.”
Rosanna Kwok grew up in Las Vegas, Nev. –“Yes, people actually live there,” she quipped. “I have always been interested in having a career in science,” she recalled, “and it just took a bit of exploration before I found myself studying the circadian clock under the mentorship of Joanna. The most exciting and motivating thing about being a scientist is knowing that I have the resources to answer the ‘how' and ‘why' questions regarding biological phenomenon.
Her career plan is “to contribute my background and skills to the field of precision therapeutics. It is hard to predict where I will be in a few years, but my goal is to be in an environment where I am constantly challenged and growing as a scientist.”
How to get more young women and girls interested in science? “Thankfully, I do believe that there is a much greater representation of women in sciences than there has in the past,” Kwok said. “With that said, I really believe in the importance of establishing mentoring relationships when it comes to retaining the amount of women in science. I have definitely benefitted from having strong female mentors throughout my scientific career. Many girls are discouraged starting from pursuing their curiosities, or from pursuing certain career paths, and sometimes it takes a more established person in that field to tell them to just go for it, and not apologize for wanting something different than what's expected of them.”
“I believe that in order to get more people in general interested in science, there needs to be more communication between scientists and people who are not in STEM fields,” Kwok said. “Not only will this show that large scientific achievements can be made by real people, it will also help prevent the misconceptions and distrust in science that we sometimes see."
Katherine “Katie” Murphy
Katie Murphy spent her childhood in a small rural town in Lake County, Northern California. “ I grew up on a pear farm, which exposed me to the staggering amount of fruit that goes to waste if the appearance of the fruit is not perfect enough for the grocery store,” she related. “I believe we have a duty as a society to be less wasteful, and therefore I feel inspired to find ways to turn waste into useful materials."
“I discovered my interest in science as a career through a student research position in Dr. Joanna Chiu's lab at UC Davis,” Murphy said. “I believe the greatest challenges that face the world today, such as world hunger, global warming, and the energy crisis, can only be met through technological advancement. I am excited for the opportunity to develop new technologies that use cutting edge science to make the world a better place.”
As an undergraduate research assistant, she was awarded a UC President's Undergraduate Research Fellowship for the summer/fall of 2012 for her project, “Transgenic Yeast as an Organic Pesticide.” She explored the use of RNAi technology in combating the invasive pest, the spotted-wing drosphila, Drosophila suzukii.
Murphy's career plans? “I am pursuing a career in metabolic engineering,” she said. “The technology I hope to develop uses microbes to produce fuels and chemicals from ‘leftovers' such as agricultural waste and non-edible plant materials. This technology will reduce dependency on fossil fuels and provide sustainable energy alternatives."
When asked how society can engage more young women and girls in science, she commented “I think children and adolescents of both genders can benefit from greater exposure to STEM fields. In the media, scientists are often represented as evil, mad, or even downright uncool on TV shows such as The Big Bang Theory. What about a TV show where scientists and engineers are portrayed as heroes?”
The Research Scholars Program in Insect Biology, established in 2011, aims to provide academically strong and highly motivated undergraduates with a multi-year research experience that cultivates skills that will prepare them for a career in biological research. This could result in career goals that will take them to medical school, veterinary school or graduate program sin any biological sub-discipline, the administrators said. Because insects can be used as model systems to explore virtually any area of biology (population biology; behavior and ecology; biodiversity and evolutionary ecology; agroecology; genetics and molecular biology; biochemistry and physiology; cell biology), faculty in the program can provide research opportunities across the full sweep of biology.

The event is co-sponsored by Jay Rosenheim, professor of entomology, UC Davis Department of Entomology and Nematology, and by the department. Epstein is a longtime research associate and friend of Rosenheim's.
Epstein is a senior insect biosystematist for the order Lepitopdera (butterflies, moths) with the Plant Pest Diagnostics Branch, California Department of Food and Agriculture. He is a research associate for the National Museum of Natural History (NMNH), Smithsonian Institution.
Harrison G. Dyar Jr. (1866-1929) was a Smithsonian entomologist of the early 20th century. He was a taxonomist who published extensively on moths and butterflies (Lepidoptera), mosquitoes (Diptera: Culicidae), and sawflies (Hymenoptera: Symphyta). As a teenager, he studied insects, particularly moths. He received his bachelor's degree in chemistry in 1889 from the Massachusetts Institute of Technology, and his master's degree in biology from Columbia University in 1894. His doctoral dissertation (1895) dealt with airborne bacteria in New York City.
Oxford University offers this description of Moths, Myths and Mosquitoes:
"On September 26, 1924, the ground collapsed beneath a truck in a back alley in Washington, D.C., revealing a mysterious underground labyrinth. In spite of wild speculations, the tunnel was not the work of German spies, but rather an aging, eccentric Smithsonian scientist named Harrison Gray Dyar, Jr. While Dyar's covert tunneling habits may seem far-fetched, they were merely one of many oddities in Dyar's unbelievable life.
"For the first time, insect biosystematist Marc E. Epstein presents a complete account of Dyar's life story. Dyar, one of the most influential biologists of the twentieth century, focused his entomological career on building natural classifications of various groups of insects. His revolutionary approach to taxonomy, which examined both larval and adult stages of insects, brought about major changes in the scientific community's understanding of natural relationships and insect systematics. He was also the father of what came to be known as Dyar's Law, a pragmatic method to standardize information on insect larval stages as they grow. Over the course of his illustrious career at the U.S. National Museum, Smithsonian Institution from 1897-1929, Dyar named over 3,000 species, established the List of North American Lepidoptera, an unrivaled catalog of moths and butterflies, and built one of the nation's premier lepidoptera and mosquito collections.
"However, Dyar's scientific accomplishments are a mere component of this remarkable biography. Epstein offers an account of Dyar's complicated personal life, from his feuds with fellow entomologists to the scandalous revelation that he was married to two wives at the same time. Epstein also chronicles Dyar's exploration of the Baha'i faith, his extensive travels, his innumerable works of unpublished fiction, and the loss of his wealth from bad investments. Comprehensive and engaging, Moths, Myths, and Mosquitoes will delight entomologists and historians alike, as well as anyone interested in exploring the zany life of one of America's virtually unknown scientific geniuses."
Epstein researches and writes on evolution and classification of moths and their biodiversity, and develops identification tools for moths that threaten agriculture. He served with NMNH's Department of Entomology (1988-2003), co-founding the department's Archives and Illustration Archives.
Epstein's research on caterpillars, including images and videos, is featured in the NMNH exhibit "More than Meets the Eye." He was a guest on NPR's "Fresh Air" about his work on the book "Night Visions: the Secret Design of Moths." Epstein's published work includes a Smithsonian monograph on limacodid moths and the article "Digging for Dyar: the Man Behind the Myth" with Pamela M. Henson.
Epstein received his master's degree (1982) and doctorate (1988) from the University of Minnesota.

His seminar is from 12:10 to 1 p.m. in 122 Briggs Hall. Professor Jay Rosenheim is the host.
"Invasive arthropod vectors may threaten natural ecosystems, agriculture, or human health by promoting either new outbreaks of novel pathogens or more severe outbreaks of native pathogens," Daughtery, says in his abstract. "In California vineyards, the glassy-winged sharpshooter (Homalodisca vitripennis) is considered a major pest because it is a vector of Xylella fastidiosa, an endemic bacterial pathogen that causes Pierce's disease.
"I have been working to understand the mechanism by which this invasive vector is able to drive more severe disease outbreaks than are native sharpshooters. Experiments have included comparative tests of transmission efficiency among sharpshooter species, characterization of vector behavior with respect to host infection status, estimates of pathogen spread and the role of seasonality, and tests of the efficacy of vector control at limiting pathogen spread. Collectively, the results suggest that H. vitripennis is not inherently efficient at transmitting or spreading the pathogen relative to its native counterparts. Rather, this invader's ability to promote severe disease outbreaks likely stems from its ability to achieve high population densities in certain environments--an outcome that can be mitigated via biological and chemical control."
Daugherty received his bachelor's degree in biological sciences, with a minor in geology, in 1995 from UC Davis, and his master's degree in biological sciences in 2000 from Illinois State University. He earned his doctorate in integrative biology in 2006 from UC Berkeley. He served as a postdoctoral researcher at UC Berkeley's Department of Environmental Sciences, Policy & Management from 2006 to 2009 and then became a USDA postdoctoral fellow there in 2008-2009. Daughtery joined the faculty of UC Riverside's Department of Entomology in 2009.
