Rader, an associate professor, says she is broadly interested in pollination ecology, landscape ecology and plant–animal interactions in natural and human-modified landscapes. She is currently working on projects that investigate the ways in which plant and animal biodiversity respond to global change and the performance of wild and managed insect pollinators in horticultural crops.
She writes on her website: "I am a community ecologist and my research focuses on plant–animal interactions in natural and human-modified landscapes. I am interested generally in the ecology of plants and animals in different types of habitats and landscapes and how they respond to differing management practices and global change. My current projects relate to wild and managed insect pollinators, their efficiency at pollinating horticultural crops and finding ways to improve fruit yield and quality by understanding their life history needs."
Rader holds a bachelor of environmental science (1998) from the University of New South Wales, Sydney, Australia. She obtained both her master's degree (2005) and doctorate (2011) from James Cook University, Cairns, Australia. Her master's thesis: "Vertical Distribution, Resource and Space Use in a Tropical Rainforest Small Mammal Community." For her doctorate: "The Provision of Pollination Ecosystem Services to Agro-Ecosystems by a Diverse Assemblage of Wild, Unmanaged Insect Taxa." She won a 2017- 2020 Australian Research Council Discovery Early Career Researcher Award.

Gulia-Nuss investigates the fundamental questions related to vector biology and vector-parasite interaction. "I am particularly interested in aspects of invertebrate reproductive physiology, nutrient allocation, and vector competence and population genomics," she writes on her website.
"CRISPR-Cas9 is transforming non-model organism research; however, successful gene editing has not yet been reported in ticks," Gulia-Nuss says in her abstract. "We have developed a successful embryo injection protocol for the black-legged tick, Ixodes scapularis, the first for any chelicerate species, and used this protocol for genome editing with CRISPR-Cas9. These results provide innovative tools to the tick research community that are essential for advancing our understanding of the vector biology and the host-vector-pathogen interactions."
Educated in India, she received three degrees from Maharshi Dayanand University, Rotak: her bachelor's degree in 1997; her master's in 1999 and her doctorate in 2006.

Plant biochemist Eric Conn in his Briggs Hall office. - "Why is the spike protein called a glycoprotein?"
- "When you get ivy poisoning, where do you expect that the active ingredient (urushiol) will accumulate?”
- "Who was the scientist at the UC Davis Genome Center that came out with the idea of using papain protease to reduce saliva viscosity?"
Those were some of the questions that the 60 undergraduate students competing in the first-ever UC Davis Eric Conn Biochemistry Quizzes answered, and the two winning teams will now compete against two teams from Cardiff University, UK.
The answers: To break disulfide bridges; Because it is decorated with sugar; In the cell membrane; and Lutz Froenicke.
More than 300 attendees ZOOMed in to watch the Feb. 20 competition. The event can be viewed online at https://youtu.be/Y9T9ayRXyYE.
“I thought the quizzes would help students get out of the ZOOM routine," said organizer-moderator Walter Leal, UC Davis distinguished professor of molecular and cellular biology and a former chair of the UC Davis Department of Entomology. "But I did not envision that there would be so much interest. The response was overwhelming, and students showed a genuine interest in the activity. They recorded videos for self-introduction, studied for the quizzes, and--more importantly--made new friends.”
Two teams emerged victorious: Ironic Bonds Team and the Gibbs Team.
“We are planning a global event on Wednesday, March 10, with our UC Davis players challenging UK's Cardiff University,” Leal announced. UC Davis Chancellor Gary May will deliver the welcome address.
The three-game virtual event, to begin at 11 a.m., Pacific Time on Zoom, will first pit UC Davis vs. UC Davis, and then Cardiff vs. Cardiff to determine the players in the championship game. The public is invited to view the event by registering here: https://tinyurl.com/dmnftsuj
“I am absolutely delighted to provide this opportunity for our students to learn biochemistry, have fun, work as teams, and build international ties,” Leal said. “Yes, remote learning is challenging, but it also creates new opportunities.”
UC Davis students who will compete in the Cardiff University event: Catherine Rodriguez, Jiaying Liu, Kelly Brandt, Aly Lodigiani, and Efrain Vasquez Santos of the Ironic Bonds Team; and Brandon Matsumoto, Tina Luu, Yasi Parsa, Esha Urs, and Kathryn Vallejo of the Gibbs Team.
The format of the game will be three questions per team, alternating one question for each team. “In the event of a tie,” Leal said, “each team will be asked one question at a time until we break the deadlock.”
While the teams work on the questions, Dr. Dean Blumberg, an epidemiologist and chief of Pediatric Infectious Diseases, UC Davis Children's Hospital, will answer questions about vaccines and vaccinations.
In an exit survey, the Eric Conn Biochemistry Quizzes drew such comments as:
- “It was wonderful....a nice way for students to showcase their knowledge to their families and friends and a wonderful tribute to a great UCD scientist. Kudos to Professor Leal for putting it together.”
- “This was a super fun event and I wish we could have the opportunity to have something like this again. It was a really good review of the material we learned.”
- "I am very proud of the students and hold both students and faculty in highest regard, very respectful and smart."
- "Congratulations to all that played today. You are inspiring young individuals and we know you will leave a mark on your chosen fields of study.”
- "Very impressed with the caliber of students involved. Great game!”
- "I wanted to play!"
Eric Conn (1923-2017), a member of the UC Davis faculty for 43 years, was the third recipient of the UC Davis Prize for Teaching and Scholarly Achievement. Described as an excellent teacher and researcher, Conn received the Academic Senate's Distinguished Teaching Award in 1974 and the Academic Senate's highest honor, the Faculty Research Lecturer Award, in 1977. He won the UC Davis Prize for Undergraduate Teaching and Scholarly Achievement in 1989.

That's the title of a virtual seminar to be presented Wednesday, Feb. 24 by postdoctoral scholar Jessica Kansman of the Department of Entomology, Pennsylvania State University as part of the weekly winter seminars hosted by the UC Davis Department of Entomology and Nematology.
Kansman will speak from 4:10 to 5 p.m. To register and attend the Zoom seminar, access this Google form link.
"Whether it is combating the ever-changing host-plant conditions, or keeping careful watch for hungry predators and parasites--aphids have a stressful experience," Kansman says in her abstract. "My research has focused on figuring out just how much stress aphids can handle. Specifically, how plant water stress influences aphids and their natural enemies, and whether predator odors are as stressful for aphids as the predators themselves."
On her website, she says: "I am broadly interested in plant-insect interactions, abiotic/biotic stress interactions, insect ecology, and multi-trophic interactions. I am passionate about science communication, science policy, and inspiring a love of insects in children, in the college classroom, and with just about anyone I come across."
Kansman holds a bachelor's degree in entomology (2015) from Michigan State University, East Lansing, and a doctorate in plant, insect and microbial sciences (2020) from the University of Missouri, studying with Deborah Finke. As a doctoral student, she received a $116,859 grant from the U.S. Department of Agriculture "to study the effect of drought on aphid performance and behavior, indirect effects of drought on natural enemies, and how these effects cascade up to influence insect communities." The Agriculture and Food Research Initiative (AFRI) of USDA's National Institute of Food and Agriculture (NIFA) awarded the grant.
Kansman has given such presentations as "Plants vs. Insects: A Tale of Spines, Spit and Assassins." In one YouTube video on "Decoding Science," she describes aphids as "devastating agricultural pests. They feed by piercing a needlelike mouthpart into the plant tissue and they use it as a straw to suck up the sap of the plant." Aphids stunt growth and transmit viruses.
