Graduate Student Stories

Claire Murphy, a fifth-year Ph.D. candidate in the Population Biology Graduate Group, wants everyone to feel like they belong in research. Based at the Bodega Marine Laboratory (BML), Murphy studies how tiny seagrass crustaceans avoid being eaten by fish, crabs, and other predators. Since coming to UC Davis in 2020, she’s mentored 11 UC Davis undergraduates, including five independent summer research projects.

Lee Miller vividly recalls the day in 2021 when he met a woman who had lost the function of her vocal cords. In hoarse, whispering tones she explained how her voice had been instrumental to her vocation. Losing it, she said, undercut her life’s purpose. He had to listen carefully to hear her faint words, but the lesson “was really powerful.”

It’s not what you do, it’s how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, according to new work by biologists at the University of California, Davis, who studied how teeth in certain fishes evolved in response to food sources and habitats.

Their work was published Feb. 26 in Nature.

Victoria Watson-Zink, Ph.D. ’22, a postdoctoral evolutionary marine biologist, received the Howard Hughes Medical Institute’s Hanna H. Gray Fellowship last month. This year’s fellowship supports the transition of 25 early-career scientists to leading labs and becoming tenured faculty.

A mussel bed along Northern California’s Dillon Beach is as healthy and biodiverse as it was about 80 years ago, when two young students surveyed it shortly before Pearl Harbor was attacked and one was sent to fight in World War II. 

The mosquito-borne Zika virus is known for causing microcephaly, a birth defect in which abnormal brain development results in a smaller-than-expected head. A new study published Jan. 13 in mBio shows that the Zika virus hijacks a host protein called ANKLE2, which happens to be important for brain development, to assist its own reproduction. Because Zika, unlike most related viruses, can cross the placenta, this can have disastrous consequences in pregnancy.

Graduate student Nathaniel (Nate) Herrera has used his last year at UC Davis to springboard a career in STEM teaching. Herrera, who joined UC Davis in 2021, studies sex differences in cardiac physiology within the Molecular, Cellular and Integrative Physiology Graduate Group.

The genetics behind the alternating sexes of walnut trees has been revealed by biologists at the University of California, Davis. The research, published Jan. 3 in Science, reveals a mechanism that has been stable in walnuts and their ancestors going back 40 million years — and which has some parallels to sex determination in humans and other animals.

Sam Arcement—Director of Graduate Academic Programs for the College of Biological Sciences, and the program coordinator for the Molecular, Cellular, and Integrative Physiology (MCIP) Graduate Group—has been honored with the 2024 Outstanding Graduate Program Coordinator Award from the Office of Graduate Studies. This year saw a record number of nominations. “Sam tirelessly ensures that our needs and concerns are heard and addressed,” said one MCIP student, who praised Arcement’s dedication to student advocacy.

Commitment. Passion. Empathy. These descriptors were just a few of the plaudits the winners of the 2024 Graduate Program Advising and Mentoring Award received in their nomination letters.

“[This professor’s] mentorship is always the perfect balance of pushing you to your full capacity, while also supporting at a level that fosters independence, creativity and self-ownership.”

“[This professor] combines a deep sense of empathy with a steely commitment to student development.”
