Hammock will present a plenary lecture on Thursday, May 31, offering an overview of the current state of the science in the area of oxidized lipids.
ISSFAL is “the leading showcase of what is new, exciting, and interesting in science and research in this field,” said executive committee member and organizing committee chair Hee Yong Kim, who serves as chief of the laboratory of Molecular Signalling for the National Institute of Health's National Institute on Alcohol Abuse and Alcoholism (NIH/NIAAA).
Hammock is known for his work on using natural chemical mediators to control inflammation and intractable pain. He continues as the founding director of the campuswide Superfund Research Program--this is the 31st year--and the NIH's National Institute of Environmental Health Sciences (NIEHS) Combined Analytical Laboratory. He has directed the NIH/ NIEHS Combined Analytical Laboratory for 25 years.
Hammock co-discovered the soluble epoxide hydrolase, and many of his more than 1100 publications and patents are on the P450 branch of the arachidonate cascade where the soluble epoxide hydrolase degrades natural analgesic and anti - inflammatory compounds. The founder of several companies, he has helped raise more than $50 million in private capital, and currently is chief executive officer of the Davis-based EicOsis, where an orally active non- addictive drug for inflammatory and neuropathic pain is being developed for human beings companion animals. EicOsis is supported by several seed-fund grants and a NIH/NINDS (National Institute of Neurological Disorders and Stroke) Blueprint Development Grant.
Highly honored by his peers, 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 the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics. He is the first McGiff Memorial Awardee in Lipid Biochemistry.
The Eicosanoid Research Foundation recently honored him for work on oxidized lipids. (See more on his website)
But have you ever heard of a song featuring the three-cornered alfalfa hopper, Spissistilus festinus, and another one spotlighting the male insect organ, the aedeagus?
And composed by a graduate student at the University of California, Davis, and performed by seven insect-attired UC Davis doctoral students?
That's what happened during the recent UC Davis Picnic Day celebration when the septet gathered in front of Briggs Hall to perform three songs composed by talented musician and entomologist Michael Bollinger, enrolled in the master's degree program, UC Davis Department of Entomology and Nematology. The group performed Bollinger's compositions, “E Major Homeboy (Spissistilus festinus),” “Tragedy (of the Clocks)," and "Jackson's Song (Aedeagal Bits)," as well as a cover song, “Island in the Sun” by Weezer.
The performance went well. Very well. So did Picnic Day.
“My goal was to make sure Picnic Day worked overall, and that, for the band, the sounds were balanced and each of the elements could be heard,” said emcee and band member Brendon Boudinot, president of the UC Davis Entomology Graduate Student Association (EGSA) and a doctoral candidate specializing in ant evolution and classification.
The “Entomology at UC Davis” exhibit at Briggs Hall, the work of the UC Davis Department of Entomology and Nematology, won the campuswide “At One With Nature” category. And the band? It drew loud applause and high praise from the standing crowd.
Their name: “The Entomology Band.” (No take-offs of the iconic “Beatles,” “Buddy Holly and the Crickets” or “Adam and the Ants.”)
Bollinger's original songs capped a day of insect-related activities that included maggot art, cockroach races, nematode identification, scavenger hunts, and honey tasting.
- Molecular geneticist and drummer Yao “Fruit Fly” Cai of the Joanna Chiu lab, dressed in a fruit fly costume, Drosophila melanogaster, which he described as “our favorite model organism in Insecta!”
- Bark beetle specialist and rhythm guitarist Jackson “Darth Beetle” Audley of the Steve Seybold lab, portrayed an Asian longhorned beetle, Anoplophora glabripennis
- Honey bee researcher and bass guitarist Wei “Silverfish” Lin of the Brian Johnson lab, wore a costume that celebrated his moniker, Lepisma saccharina, a small, wingless insect in the order Zygentoma
- Ant specialist and keyboard artist Zachary “Leptanilla” Griebenow of the Phil Ward lab, dressed as “a generic male leptanilline ant (Formicidae: Leptanillinae).” He said: “The yellow color “is not anywhere near so vivid in real life.”
- Systematist and tenor saxophonist Jill “Jillus Saximus” Oberski of the Phil Ward lab, dressed as a “generalized heteropteran,” which she described as “most likely a member of the family Acanthosomatidae (shield bug) or Pentatomidae (stink bug). My family and friends have called me Jillybug, so I came to be the band's representative of Hemiptera.”
- Molecular geneticist and vocalist Christine “The Clock” Tabuloc of the Joanna Chiu lab, wrapped herself in butterfly wings
- Ant specialist and bass guitarist Brendon “Hype Man-tis” Boudinot of the Phil Ward lab, dressed in a green helmet, a blue and gold EGSA bee shirt and a UC Davis cow costume to showcase his department and campus-wide love of bovines.
The seven band members share a love of music.
Drummer Yao Cai, who grew up in Southeast China and holds an undergraduate degree in plant protection and a master's degree from China Agricultural University, has been playing drums since age 17. “We formed as a short-lived band for a show. After that, I realized that I really wanted to keep playing and improved my drum techniques. Thus, we started another band in college and played for six years in college, as an undergrad and graduate student.
“We were all agriculture-related majors and we mainly wrote original songs,” recalled Cai. The campus concerts sometimes drew a thousand spectators. “After we graduated from graduate school, we stopped. I really missed the time playing drums with folks since I came to UC Davis. Fortunately, after a ‘gap year,' Jackson, Michael and I started jamming in September 2017. Later on, our current talented members joined.”
“It is very interesting that I was in a band that was the first band in Department of Entomology in China Agricultural University and now we started the first band in Department of Entomology at UC Davis.”
Rhythm guitarist Jackson Audley said he “started learning to play the guitar when I was about 11-12 ish. The first band I joined was a Blink-182 cover band, in which I played the bass guitar, and we played together for most of eighth grade. Then in early high school I joined a Smashing Pumpkins/Radiohead cover band as the second guitarist. Shortly after joining that band, we started making predominantly original music. By the end of high school, we had played a few small shows around the Atlanta area and had recorded a few songs. Unfortunately, the band did not survive the transition into university and we broke up.”
Since then he's mostly played “for fun and I like to jam with folks.”
Jill Oberski, a native of Twin Cities, grew up mostly in Chaska, Minn., “a sleepy suburb of Minnesota.” She received her bachelor's degree in Macalester College in Saint Paul, Minn., where she double-majored in biology and German studies.
“I started playing the piano in kindergarten, and switched to saxophone in fifth grade,” Oberski related. “I played classical and jazz in my school bands from sixth grade through college, and pit orchestra / pep band / marching band in high school as well. I've always been better at classical than rock/jazz/Latin.”
“I probably reached my highest point in late high school, when I served as co-section leader for the saxes in the Minnesota all-state symphonic band--we even got to play a concert in Minneapolis' orchestra hall. These days I'm only involved in the entomology band and some very casual ukulele playing.”
Brendon Boudinot, who received his bachelor's degree in entomology at the Evergreen State College, Olympia, Wash., performed on a metallic sky-blue bass. “I just love art,” he said. “Music is a family thing for me in a number of different ways. Although I have played instruments alone or in groups for many years, nothing really clicked in me until I heard Michael and Yao play together. They shred.”
“The Entomology Band is special to me, and I am just glad I could be a part of it.”
Vocalist Christine Anne Tabuloc, who grew up in the Los Angeles area and received her bachelor's degree from UC Davis in biochemistry and molecular biology, says she does not play an instrument. “I'm far less talented than everyone else in the group,” she quipped. “I've been singing for as long as I can remember. I've been writing lyrics since elementary school. However, I never got around to getting music written for them. I was in choir before and have had solos but that's pretty much it.”
Bass guitarist Wei Lin, who grew up in Xiamen, "a beautiful island in southern China," received his bachelor's and master's degree in China Agricultural University, majoring in plant protection and entomology. “This was my first experience in a band. I just started to learn bass last year when this band was built.”
Following the four-set gig, Boudinot told the appreciative crowd, “That's all we know!”
Pending performances? “The band,” he said, “is on hiatus.”
Page, a pollination ecologist, was one of 69 awardees selected from more than 3600 applicants. Her fellowship is funded by the Department of Defense.
“The fellowship is well deserved,” said Williams, her major professor and a pollination ecologist and a UC Davis Chancellor's Fellow. “Maureen is a talented researcher, who shows a real passion for her research that is combined with a highly analytical meticulous approach.”
Of her project, Williams said: “Her work melds careful field sampling with advanced analysis, including computational optimization modeling. It will move existing research to a new level by exploring the nutritional basis of competitive interactions among pollinators. The project builds from a solid foundation but his highly innovative. Its results should be of tremendous value to the scientific community, but are also highly relevant for decision making to promote sustainable food systems for California and beyond.”
Page received her bachelor's degree in biology, cum laude, from Scripps College, Claremont, Calif., in 2016, and then enrolled in the UC Davis entomology graduate program, with a career goal of becoming a professor and principal investigator.
“I became interested in UC Davis because I was interested in working in Neal's lab,” she related. “After my sophomore year of college, I participated in National Science Foundation's Research Experiences for Undergraduates (NSF REU) with the Chicago Botanic Gardens. One of the professors I was working with, Jennifer Ison, told me that my research interests aligned well with the work coming out of Neal's lab and I quickly realized she was right.”
“I even bookmarked the Williams lab webpage so I could check for recent papers!” Page said. “Neal is an even better advisor than I could have hoped for and I feel very grateful to be a part of UC Davis Department of Entomology and Nematology.”
Her dissertation research focuses on using plant-pollinator interaction networks to (1) assess the impact of honey bee introductions on native plant pollination and (2) optimize wildflower plantings to simultaneously support honey bee health and diverse native bee communities.
“I've always loved flowers and I think my love of bees grew out of my academic interest in pollination ecology and a desire to apply my talents towards research that would benefit farmers and pollinator conservation efforts,” said Page, a native of San Francisco but who grew up in Ashland, Ore.
As a volunteer researcher for Southern Oregon University, she worked on a watershed project in the Klamath-Siskiyou Wildlands Center, and was named the City of Ashland's Conservationist of the Year in April 2012. The city honored her at its Earth Day celebration.
Keenly interested in bee research, Page received a 2013 Scripps Environmental Research Grant to establish a solitary bee monitoring program at the Bernard Field Station in Claremont. She created a reference collection and species list of bee diversity at the field station, gaining experience collecting, pinning and identifying bee specimens. She presented her findings at the Scripps Undergraduate Research Symposium. Page later worked on a project categorizing pollen deposition by the yellow-faced bumble bee, Bombus vosnesenkii to California figwort, Scrophularia california.
What fascinates her about bees? “Tough question!” said Page, who is the first entomologist in her family. “Bees are so very interesting for so many different reasons! I'm particularly fascinated by the relationship between bees and flowers--with bees acting as pollinators and flowers offering bees important pollen and nectar resources. I think the biggest misconception is that all bees are honey bees. In fact, there are more than 20,000 species in the world, only 7 of which are considered honey bees!”
An average day?
“My field season has started, so on an ‘average day' I'm at one of my lab's wildflower plantings by 7 a.m. and driving home with coolers of bees and flowers around 7 p.m.,” Page said. “The most fun part of my fieldwork is using something called a ‘mobile bouquet' to measure single-visit pollen deposition by different pollinator taxa to different plant taxa.”
Page was awarded a grant from the Davis Botanical Society earlier this year, and won second place in the graduate students' poster competition at the 2018 UC Davis Bee Symposium for her poster, “Impacts of Honey Abundance on the Pollination of Eschscholzia californica. Last year she received a Northern California Botanists' Grant and a Davis Botanical Society Grant.
Eager to reach youth about the importance of pollinators, Page began volunteering in 2016 for the Center for Land-Based Learning, mentoring students from Sacramento High School, and engaging them in hands-on conservation science at Say Hay Farms, a 20-acre family farm in Yolo County. She has taught students at her Davis area field site about the benefits of providing wildflower habitat for pollinators.
The UC Davis doctoral student has also presented lectures at the Hoes' Down Harvest Festival, Yolo County, on “Pollinators on the Farm” and led a kids' bug hunt. She presented an invited lecture on “Beneficial Insects in Home Gardens” to the El Dorado Master Gardeners, part of the UC Cooperative Extension program, and volunteered at their other activities.
Page serves as secretary of the UC Davis Entomology Graduate Student Association. In her leisure time, she enjoys “baking, rock climbing, learning new things, and sketching--mostly-flowers, bees, and sometimes butterflies.”
Eastern Finland University in Kuopio will be his host institution, where he will work with James Blande of the Chemical Ecology Group, Department of Environmental Sciences. Grof-Tisza met Blande while he was collaborating with Karban--his major professor and now his postdoctoral advisor--on a project involving plant-plant communication and induced resistance within sagebrush.
“The focus of my Curie postdoc will be to continue this research and to investigate community-wide effects of volatile-mediated communication,” Grof-Tisza said. “I will conduct field research in the Eastern Sierra in the spring and summer and will spend the rest of the year in Finland conducting laboratory experiments and analyzing samples collected over the field season.”
Grof-Tisza's dissertation work involved investigating how bottom-up and top-down forces regulated a focal herbivore, the Ranchman's tiger moth (Arctia virginalis; the wooly bear caterpillar that Karban has been studying since 1983) within the Bodega Marine Reserve.
“Through this work, I became interested in plant defenses, both mechanical and chemical – the primary host plant of A. virginalis contains alkaloids, which are known to deter herbivores.” He also has collaborated on several projects with his lab mate, Eric LoPresti, who studies the efficacy of sand-entrapment as a defense in sticky plants.
“I applied to the Marie Currie Fellowship to continue studying plant defenses as well as learn laboratory techniques, including those pertaining to gene expression and mass spectrometry,” said Grof-Tisza who received his bachelor's degree in molecular biology, summa cum laude, at Frostburg (Md.) State University, and then worked as a biochemist in the biotech industry prior to enrolling in graduate school at UC Davis. As a member of the Ecology Graduate Group, he received his doctorate in 2015 from UC Davis, working with advisors Richard Karban and Marcel Holyoak, a professor in the Department of Environmental Science and Policy.
“This second postdoc,” Grof-Tisza said, “will allow me to combine the ecological knowledge I have gained as a graduate student with the laboratory skills I learned earlier in my career.”
In his fellowship proposal abstract, Grof-Tisza noted “Plants have evolved an impressive defense system to combat herbivores. These defenses include morphological structures like spines and secondary metabolites that have toxic, repellent, or antinutritional effects on consumers. Many plant defenses are constitutively expressed, but some are induced in response to herbivore damage. Damaged plants emit volatile organic compounds (VOCs) into the environment that may induce defenses in adjacent, undamaged tissue or may be eavesdropped by neighboring plants, enabling them to prime their own resistance response prior to attack.”
“While once controversial, this plant-plant communication resulting in a VOC-induced phenotypic response that reduces damage from attacking herbivores has been demonstrated in over 50 species,” he wrote. “Recently, researchers have found distinguishing VOC blends among sagebrush (Artemisia tridentata) referred to as chemotypes. Field experiments demonstrated that communication between A. tridentata plants of the same chemotype resulted in less damage by herbivores compared to that between plants of different chemotypes. Chemotypes were also found to be highly heritable.”
Grof-Tisza wrote that “this is consistent with the hypothesis that volatile communication evolved as a within-plant warning mechanism due to limited vascular signaling. Because emitted volatile cues become available to potential competitors of the same or different species, selection for cues that are more private would likely be of greater benefit to the emitter. At the time of this study, only two A. tridentata chemotypes had been identified. More recent work has found an additional six chemotypes.
“Here we propose to rigorously test the ecological consequences of chemotypic variation and the processes that maintain it. Through synergistic efforts combining my expertise in field ecology and plant-insect interactions and that of the host and collaborators in ecological chemistry and molecular biology, we will forward the field of volatile-mediated plant-plant interactions.”
Grof-Tisza has published his work in a number of journals, including Ecology, Evolution and Ecology, Journal of Animal Ecology, Journal of Chemical Ecology, Ecological Entomology, Bulletin of the Ecological Society of America, Biological Conservation and Oikos. He served as an adjunct professor with the Department of Science and Engineering, American River College, Sacramento, from 2015 to 2016.
Born in Queens, N.Y., but raised in Somerset, Pa., Grof-Tisza has resided in Davis since 2007.
In fact, it was her childhood curiosity about a yellow fever vaccination that sparked her interest in mosquitoes.
In her youth, Olivia traveled with her parents and brothers to “off-the-beaten-path” locations. “So I was exposed to vector-borne disease awareness from a young age,” she recalled. “When I was 8 years old, I remember getting the yellow fever vaccination and being curious about why I had to get it for a trip to Southern Africa. I think that was my defining moment when I learned mosquitoes are more than just annoying. Since then, I've slept under many mosquito nets and am no stranger to mosquito bites.”
“I didn't think much about making a career out of those 'skeeters, though. I attended Cornell University as undergraduate, where I studied global public health from multiple perspectives. It wasn't until I became a research assistant in Dr. Laura Harrington's lab that I became fascinated with mosquito biology and decided to pursue a career in medical entomology.”
Winokur, who received her bachelor's degree in 2015 from Cornell University, majoring in Interdisciplinary Studies and focusing on the environmental effects on human health, enrolled in the UC Davis graduate program in 2016 as a Ph.D entomology student with a designated emphasis in the biology of vector-borne diseases.
She studies with major professor and UC Davis alumnus Christopher Barker, associate professor and associate researcher in the Department of Pathology, Microbiology and Immunology, School of Veterinary Medicine, who doubles as a graduate student advisor in the UC Davis Department of Entomology and Nematology.
Earlier this year, Winokur received a three-year National Science Foundation Graduate Research Fellowship. A 2017 Bill Hazeltine Memorial Award also helps fund her research.
A typical day in the lab: “My days are usually a bit all over the place--I typically spend some time in the BSL-3 (Biosafety Level 3) either collecting samples from infected mosquitoes or processing previously collected samples, some time back in the lab analyzing data and writing, and I'm still taking classes so a few days a week I spend the afternoon on the main campus.”
Born in Long Beach, Calif., Olivia grew up in Laguna Niguel, Calif., where she focused on science as a part of the Dana Hills High School Health and Medical Occupations Academy. Olivia also played basketball at Dana Hills and helped the team win its first league title.
What drew her to UC Davis? “I grew up in California so I was familiar with UC Davis from a young age. I actually applied to UC Davis as an undergraduate, but decided to try life on the East Coast instead and attended Cornell University. While at Cornell, I learned a lot about UC Davis as most of my professors had spent some time at UC Davis during their academic tenure, and a lot of the research I was reading was coming out of UC Davis. I was excited to come back to the West Coast for graduate school so UC Davis seemed like an obvious choice!”
While at Cornell, she interned at the National Institutes of Health (NIH) in 2014, when advised by John Balbus of National Institute of Environmental Health Sciences (NIEHS), and Joshua Rosenthal, Fogarty International Center, where she coordinated and wrote an interagency proposal for climate change mitigation in middle and low-income countries under the United Nations. "I also helped develop a global clean cook stove implementation framework to advise NIH initiatives,” she said.
Winokur is a co-author of “The Impact of Temperature and Body-Size on Flight Tone Variation in the Mosquito Vector Aedes aegypti (Diptera: Culicidae): Implications for Acoustic Lures," published in April 2017, in the Journal of Medical Entomology. Several other manuscripts are accepted or in preparation.
She has given presentations at the Mosquito and Vector Control Association of California and the American Society of Tropical Medicine and Hygiene.
Dedicated to helping high school girls transition into STEM (Science, Technology, Engineering and Math) careers, Winokur is a founding board member and publicity co-chair of GOALS (Girls' Outdoor Adventure in Leadership and Science). The organization seeks “to cultivate and embolden the next generation of STEM leaders through a free, immersive, field-based summer science program for high school girls.”
“GOALS is for high school girls, inclusive of cis, trans, and gender nonbinary youth who identify with girlhood, to learn science hands-on while backpacking through the wilderness,” Winokur related. “I have worked with an incredible team of UC Davis affiliates to create GOALS to increase opportunities for high school students who identify with girlhood from backgrounds traditionally underrepresented in STEM. Our first trip is happening this summer!” This year's program takes place July 21 to Aug. 5.
Winokur is also a part of the Letters to a Pre-Scientist program “so I get to be a pen-pal to an elementary school student to talk about science!” In addition, she serves as the treasurer of the UC Davis Entomology Graduate Student Association.
Delighted to return to California after being on the East Coast, Winokur spends her leisure time outdoors hiking and backpacking “and exploring the beautiful places near Davis like the Lake Tahoe area and Yosemite. I taught backpacking and wilderness survival skills for Cornell Outdoor Education during college. Additionally, I'm a trivia nerd so I watch a lot of Jeopardy! and play pub trivia with my entomology colleagues weekly. I also enjoy drawing, reading, playing board games, and doing jigsaw puzzles. When I get the chance I enjoy traveling as well--I just returned from Belize and I'll be in Denmark in July!”
After finishing her Ph.D., Winokur plans to remain in academia, but “I'm unsure exactly what that will look like! I really enjoy research, teaching, and mentoring so I'd like to have a career where I can do all of these. I also plan to have a career where I can conduct translational research with broad global health implications, engage non-scientists, create tools to help decision makers mitigate vector-borne disease burden worldwide, and encourage interest and diversity in STEM.”
