The award is part of the Revolutionizing Innovative, Visionary Environmental Health Research (RIVER) Program of the National Institutes of Environmental Health (NIEHS). This award is based on a track record of innovation and a ‘visionary' proposal to address serious problems in environmental health.
Hammock, who holds a joint appointment with the UC Davis Department of Entomology and Nematology and the UC Davis Comprehensive Cancer Society, is known for his expertise in chemistry, toxicology, biochemistry and entomology. He meshes all four sciences in his 50-year research on how environmental chemicals impact human health.
“I am thrilled to receive the RIVER award,” said Hammock, who joined the UC Davis faculty in 1980 and now devotes much of his research toward environmental health. “The National Institutes of Health has many institutes and several of them have funded my laboratory over the years. But it is the NIEHS that most closely matches my interests. They have supported my work since I was a graduate student, so I am particularly thrilled they have shown such high confidence in the science and work our laboratory does. This award certainly recognizes the current and past members of the laboratory who have been so productive and innovative.”
The program provides $6 million in funding over an eight-year period “to give scientists greater intellectual and administrative freedom as well as sustained support to achieve greater scientific impact,” according to NIEHS officials. RIVER provides a select few scientists with great latitude in addressing the most pressing scientific problems.
“Professor Hammock is especially deserving of this recognition for his important research over many years,” said Helene Dillard, dean of the UC Davis College of Agricultural and Environmental Sciences. “Environmental health is central to the mission of our college, and we anticipate that this award will empower him to continue making advances in areas with the potential to impact human well-being.”
Ken Burtis, faculty advisor to the Chancellor and Provost and past Dean of Biological Sciences at UC Davis, said it would be difficult to find “a more deserving scientist to invest in than Bruce Hammock.”
“We both worked in the same building, and Bruce was one of the most hard-working, creative and enthusiastic colleagues I knew,” Burtis said. “The grant process often limits innovation. The intellectual freedom NIEHS is providing Hammock makes our university shine and is a smart investment on the part of the agency. Their investment in him in the past paid off and RIVER will pay off even more in the future.”
When asked how the award would change his life, Hammock, a kayak enthusiast and instructor, responded: “I will give up kayaking the harder rivers, I certainly do not want to drown and have to give any of the funding back. Having been given this great freedom, it will be hard to live up to the expectations.”
Hammock, who has directed the NIEHS-UC Davis Superfund Research Program for the past 35 years, said many of his UC Davis collaborators are affiliated with the Superfund Program, including:
- Professor Aldrin Gomes who holds a joint appointment with the Department of Neurobiology, Physiology and Behavior, College of Biological Sciences, and the Department of Physiology and Membrane Biology, School of Medicine;
- Fawaz Haj, who holds a joint appointment with the Department of Nutrition, College of Agricultural and Environmental Sciences, and the Department of Internal Medicine, School of Medicine
- Research scientist Christophe Morisseau of the Hammock lab, Department of Entomology and Nematology and the Comprehensive Cancer Center, and
- Cardiologist Nipavan Chiamvimonvat of the Division of Cardiovascular Medicine, Department of Internal Medicine, UC Davis Health System
“Bruce had been wonderful supporting students through running a training grant and particularly bringing diverse scientists together with the NIEHS Superfund Program,” said Chiamvimonvat. “It has been such a privilege to be part of this exciting program to understand the mechanisms of environmental contaminants on human health. His pioneering work on novel targets to combat inflammation has far-reaching applications, not only in pain, but also in other diseases including cancer and cardiovascular diseases, the two most common causes of morbidity and mortality.”
Gomes explained that rather than trying to find biological markers for individual environmental chemicals, this Superfund group is working together to find universal markers of stress and disease and understand how to prevent these diseases. ‘By stabilizing mitochondria, the endoplasmic reticulium and other cell organelles to stress,” Gomes said, “we are reducing toxicity, as well as understanding the very basis of tissue damage by commonly used drugs and pesticides and how to reverse it.”
Michael Lairmore, dean of the UC Davis School of Veterinary Medicine, said he was pleased to hear that Hammock has won the NIEHS River Award. “Bruce is very deserving of this award,” Lairmore said. “He has pioneered trans-disciplinary research across campus and has engaged faculty in multiple colleges and schools to transform the way we treat diseases in multiple species. His creative approaches blend his natural curiosity with practical ways to translate his research findings into real world solutions to disease processes.”
“By providing research freedom through the RIVER award to Bruce Hammock, NIH made a remarkable decision,” said Scott Fishman, director of the Center for Advancing Pain Relief, Fullerton Endowed Chair in Pain Medicine, and executive vice chair of the Department of Anesthesiology and Pain Medicine for the UC Davis School of Medicine.
“For example, Bruce sought me out shortly after I arrived at UC Davis with interest in reducing pain and our excessive use of opioids,” Fishman said. “Over time, he went on to develop an experimental pharmaceutical that is a promising unique non-opioid drug for treating chronic pain that will enter human trials this fall. With Hammock as a recipient, the NIH RIVER Program has declared its commitment to recognizing basic scientists who are developing profound solutions that address the opioid crisis.”
Harvard Medical School researcher and former physician, Dipak Panigraphy, said that “The pioneering studies from the Hammock laboratory not only have elucidated how certain environmental contaminants increase cancer risk, but our collaborative work shows promise for preventing metastasis and recurrence of cancer following surgical tumor resection and chemotherapy. These potentially paradigm shifting studies show that preoperative or peri-chemotherapeutic management of inflammation may stave off cancer recurrences.”
Said Hammock: “We would not have this without the scientific and intellectual input of Cindy McReynolds, program manager of the Superfund Program. Of course RIVER is a complement to the existing and past scientists who have worked on this project.”
The RIVER program is “the centerpiece of an emerging effort to support people, not projects, by providing support for much of an independent research program for outstanding investigators and giving them intellectual and administrative freedom, as well as sustained support, to pursue their research in novel directions in order to achieve greater impacts,” according to the NIEHS-RIVER website. “The RIVER program rewards outstanding environmental health sciences researchers who demonstrate a broad vision and potential for continuing their impactful research with increased scientific flexibility, stability in funding, and administrative efficiency.”
Nationally recognized for his achievements, Hammock is a fellow of the National Academy of Inventors, which honors academic invention and encourages translations of inventions to benefit society. He is a member of the U.S. National Academy of Sciences, a fellow of the Entomological Society of America, and the recipient of scores of awards, including the first McGiff Memorial Awardee in Lipid Biochemistry; and the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics.
“Bruce Hammock and his research team are the perfect example of how UC Davis translates university research into societal impact,” said Dushyant Pathak, associate vice chancellor for Innovation and Technology Commercialization in the UC Davis Office of Research.
“As a result of their fundamental work in unraveling both insect and human regulatory biology, the Hammock laboratory elucidated a biochemical pathway that regulates inflammation, pain and senescence,” Pathak said. “Enabled by this knowledge, a novel drug candidate to treat chronic pain is expected to enter human phase 1a trials this fall--also supported by NIH. The drug is licensed by the university to EicOsis, a company that is directing its development and is a UC Davis spin-off.”
A native of Little Rock, Ark., Hammock received his bachelor's degree in entomology (with minors in zoology and chemistry) magna cum laude from Louisiana State University, Baton Rouge, in 1969. He received his doctorate in entomology-toxicology from UC Berkeley in 1973 with John Casida at UC Berkeley. Hammock served as a public health medical officer with the U.S. Army Academy of Health Science, San Antonio, and as a postdoctoral fellow at the Rockefeller Foundation, Department of Biology, Northwestern University, Evanston, Ill.
Hammock traces the history of his enzyme research to his studies in the Casida laboratory. He was researching insect developmental biology and green insecticides when he and colleague Sarjeet Gill, now a distinguished professor at UC Riverside, discovered the target enzyme in mammals that regulates epoxy fatty acids.
“My research led to the discovery that many regulatory molecules are controlled as much by degradation and biosynthesis,” Hammock said. “The epoxy fatty acids control blood pressure, fibrosis, immunity, tissue growth, depression, pain and inflammation to name a few processes.”
“Basically, I began by trying to figure out how a key enzyme, epoxide hydrolase, degrades a caterpillar's juvenile hormone, leading to metamorphosis from the larval stage to the adult insect,” Hammock said. He asked himself these questions: “Does the enzyme occur in plants? Does it occur in mammals?" It does, and particularly as the soluble epoxide hydrolase in mammals.
"It is always important to realize that the most significant translational science we do in the university is fundamental science,” said Hammock, marveling that “this work to treat pain in companion animals, horses and humans all began by asking how caterpillars turn into butterflies.”
An international team of 10 scientists, led by plant nematologist Shahid Siddique, a former research group leader at the University of Bonn, Germany, and now an assistant professor in the UC Davis Department of Entomology and Nematology, has discovered the role of a plant's endodermal barrier system in defending against plant-parasitic nematodes.
“We discovered that the integrity of the endodermis—a specialized cell layer that surrounds the vascular system and helps regulate the flow of water, ions and minerals--is important to restrict nematode infection,” said Siddique, who joined the UC Davis faculty in March after serving several years at the University of Bonn.
“We found that having defects in endodermis make it easier for parasites to reach the vascular cylinder and establish their feeding site. Although, this finding is a result of basic research, it opens new avenues to for breeding resistance against cyst nematodes in crops.”
The research, “Root Endodermal Barrier System Contributes to Defence against Plant‐Parasitic Cyst and Root‐Knot Nematodes,” is published in the July 19th edition of The Plant Journal.
Siddique collaborated with scientists from Germany, Switzerland and Poland: Julia Holbein, Rochus Franke, Lukas Schreiber and Florian M. W. Grundler of the University of Bonn; Peter Marhavy, Satosha Fujita, and Niko Geldner of the University of Lasuanne, Switzrland; and Miroslawa Górecka and Miroslaw Sobeczak of the Warsaw University of Life Sciences, Poland.
“Plant-parasitic nematodes are among the most destructive plant pathogens, causing agricultural losses amounting to $80 billion annually in the United States,” said Siddique. “They invade the roots of almond, tomato, beets, potato or soybeans and migrate through different tissues to reach the central part—the vascular cylinder--of the root where they induce permanent feeding sites.”
“These feeding sites are full of sugars and amino acids and provide the parasite all the nutrients they need,” Siddique explained. “A specialized cell layer called the endodermis surrounds the vascular system and helps regulates the flow of water, ions and minerals into and out of it. However, the role of endodermis in protecting the vascular system against invaders such as nematodes had remained unknown.”
In their abstract, the scientists noted that plant-parasitic nematodes (PPN) “cause tremendous yield losses worldwide in almost all economically important crops. The agriculturally most important PPNs belong to a small group of root‐infecting sedentary endoparasites that includes cyst and root‐knot nematodes. Both cyst and root‐knot nematodes induce specialized long‐term feeding structures in root vasculature from which they obtain their nutrients.”
“A specialized cell layer in roots called the endodermis, which has cell walls reinforced with suberin deposits and a lignin‐based Casparian strip (CS), protects the vascular cylinder against abiotic and biotic threats,” the researchers explained. “Until now, the role of the endodermis, and especially of suberin and the CS, during plant–nematode interactions was largely unknown.”
The team analyzed the role of suberin and CS during interaction between Arabidopsis plants and two sedentary root parasitic nematode species, the cyst nematode Heterodera schachtii and the root‐knot nematode Meloidogyne incognita. “We found that nematode infection damages endodermis leading to the activation of suberin biosynthesis genes at nematode infection sites.”
The research was funded by a grant from the German Research Foundation.

The California Master Beekeeper Program (CAMBP), directed by Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, is hosting two short courses in early August: one on “Planning Ahead for Your First Hives” and the other, “Working Your Colonies.”
Each will take place from 9 a.m. to 4 p.m. in the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, west of the central campus. The deadline to register is Thursday, Aug. 1.
“These courses are foundational to beekeeping husbandry excellence,” said Wendy Mather, program manager. “They are great for folks who are thinking about getting bees next season, as well as those who currently have bees and want to ensure they're doing whatever they can to ensure the success of their hives.”
The classes are not required to become a California Master Beekeeper, but are highly recommended, as “they will help folks prepare to become a science-based beekeeping ambassador,” Mather said. Instructors are Elina Niño and CAMPB educational supervisor Bernardo Niño, a staff research assistant in the Niño lab.
Planning Ahead for Your First Hives
“Planning Ahead for Your First Hives” will take place Saturday, Aug. 3 and will include both lectures and hands-on activities. Participants will learn what's necessary to get the colony started and keep it healthy and thriving. They will learn about bee biology, beekeeping equipment, how to install honey bee packages, how to monitor their colonies (that includes inspecting and monitoring for varroa mites) and other challenges with maintaining a healthy colony.
The course is limited to 25 participants. The $105 registration fee covers the cost of course materials (including a hive tool), lunch and refreshments. Participants can bring their bee suit or veil if they have one, or protective gear can be provided. For more information or to register, see https://registration.ucdavis.edu/Item/Details/572.
Working Your Colonies
“Working Your Colonies” will take place Sunday, Aug. 4 and will include both lectures and hands-on activities. Participants will learn what is necessary to maintain a healthy colony. Lectures will cover advanced honey bee biology, honey bee integrated pest management, and products of the hive. Participants also will learn about queen wrangling, honey extraction, splitting/combined colonies, and monitoring for varroa mites.
The course is limited to 25 participants per session. The $175 registration fee covers the cost of course materials, lunch and refreshments. For more information or to register, see https://registration.ucdavis.edu/Item/Details/559.
Participants can bring their bee suit or veil if they have one, or protective gear can be provided. All participants are to wear closed-toed and closed-heel shoes, long pants and a long-sleeved shirt.
The California Master Beekeeping Program uses science-based information to educate stewards and ambassadors for honey bees and beekeeping. For more information, contact Mather at email@example.com.
Rebecca Godwin won first in the poster competition for her research on trapdoor spiders and Lacie Newton won second for her oral presentation on species delimitation. Their major professor, Jason Bond, is the department's Evert and Marion Schlinger Endowed Chair in Insect Systematics.
Godwin titled her work, “Revision of New World Ummidia (Mygalomorphae, Halonoproctidae)”: Her abstract: “Ummidia is a historically taxonomically difficult group of spiders belonging to the infraorder Mygalomorphae, one of the three main lineages recognized within spiders. Mygalomorph life history and their incredibly cryptic appearance make them difficult to identify, as a result they are frequently overlooked by spider systematists. Ummidia Thorell 1875 is a wide-ranging genus of trapdoor spider found both in the Mediterranean region of the Old World and in the New World from the eastern United States south to Brazil. Taxonomic work on New World Ummidia is sparse outside of original descriptions, the most recent of which are over half a century old."
"I am revising the genus Ummidia in the Nearctic region. I have approached this taxonomic problem by examining approximately 700 specimens of Ummidia from various collections (American Museum of Natural History, Museum of Comparative Zoology, Florida State Collection of Arthropods, California Academy of Sciences, and Auburn University Museum of Natural History). Examination of museum material has seemingly confirmed the undescribed diversity of Ummidia; preliminary estimates of New World species ranging between 50 and 60, with particularly high amounts of diversity in the Florida and Virginia. This study, along with many others conducted utilizing museum collections, is indicative of the importance of natural history collections and their usefulness in discovering unknown biodiversity.”
"Previous research by Hendrixson and Bond (2005) described a new sympatric species Antrodiaetus microunicolor in the A. unicolor species complex using morphological criteria (i.e. size and setal character differences) and behavioral criteria (non-overlapping mating seasons). Subsequently, they used two molecular markers COI and 28S and discovered that A. unicolor is paraphyletic with respect to A. microunicolor. To further delineate this species complex, we implement the cohesion species concept and employ multiple lines of evidence for testing genetic exchangeability and ecological interchangeability. Our integrative approach includes extensively sampling homologous loci across the genome using a version of RADseq called 3RAD, assessing population structure across their geographic range, and evaluating ecological similarity by niche-based distribution modeling. Based on our analyses, we conclude that this species complex has two or three species in addition to A. microunicolor.”
Godwin holds two degrees from Auburn University: her bachelor's degree in zoology in 2004, and her master's degree in wetland biology in 2011. She began her doctoral studies at Auburn University in 2014, and transferred to UC Davis when Bond accepted the UC Davis position in 2018.
Godwin's research interests include taxonomy, systematics, and phylogreography of trapdoor spiders, as well as effective science communication and increasing general science literacy.
Newton received her bachelor of science degree from Millsaps College, Jackson, Miss., in 2016, and then joined the Auburn University doctoral program. Like Godwin, she transferred to UC Davis with her major professor in 2018. Newton served as an undergraduate teaching assistant at Millsaps College for “Introduction to Cell Biology” and “General Zoology,” and as a graduate teaching assistant in “Introduction to Biology” at Auburn University.
Newton now serves as a graduate teaching assistant at UC Davis for “Introduction to Biology: Biodiversity and the Tree of Life.” She won the 2019-2020 George H. Vansell Scholarship, UC Davis. Her research interests include systematics, species delimitation, and phylogeography of spiders; phylogenetics; comparative transcriptomics of troglophilic and troglobitic spiders; cave biology and conservation.
Both Godwin and Newton volunteer at the Bohart Museum of Entomology's programs on spiders and at the campuswide UC Davis Biodiversity Museum Day.
Bond joined the UC Davis faculty after a seven-year academic career at Auburn University, Ala. He served as professor of biology and chair of the Department of Biological Sciences from January 2016 to July 2018, and as curator of arachnids and myriapods (centipedes, millipedes, and related animals) at the Auburn University Museum of Natural History, from August 2011 to July 2018.
