Graduate Student Stories

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.

Each year, nearly 30 million Americans purchase a real tree for the holidays. Growing the perfect Christmas tree takes about seven years, during which farmers need to keep insects, fungal pathogens and hungry deer at bay. While researchers suspect the distinctive piney smell the trees emit plays a role in deterring these pests, not all trees smell the same, and which chemical blends confer resistance is unclear. 

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.”

Each year the college recognizes the importance of mentorship in the continued growth of both the undergraduate and graduate communities by awarding CBS Dean’s Mentorship Awards to graduate students. Funded by contributions to the CBS Dean’s Circle, the awards are open by faculty nomination to graduate students who have played a significant role in the growth and development of the younger generation of scientists. 

Jessica Bolivar, a graduate student in the Biochemistry, Molecular, Cellular and Developmental Biology (BMCDB) Graduate Group, knows firsthand the difference that one person’s mentorship can make. 

During her time at UC Davis, Bolivar has made it her mission to give back and inspire the next generation of scientists by balancing her research with a slew of community-uplifting and diversity, equity and inclusion initiatives.

The UC Davis College of Biological Sciences champions Diversity, Equity, Inclusion, and Justice (DEIJ) through the Graduate Student DEIJ Leader Fellowship program. Now in its second year, the program empowers enterprising graduate students committed to enhancing DEIJ within the CBS community by supporting projects aimed at fostering a more inclusive academic environment.
