Z. Wei

Xiaohong Wei attended the California Cattlemen's Association Convention conference and presented a poster on the topic of dispersal and risk factors for airborne E. coli in the proximity of a beef cattle feedlot. Under the supervision of Dr. Atwill, Xiaohong Wei, along with Amlan Aggrawal and Ronald Bond, conducted an exceptional study in   the Imperial Valley during the COVID pandemic. The research received significant attention from the feedlot industry, produce farm industry, supermarkets, and the US FDA. One of the publications resulting from the study is currently listed on the California Cattle Council's website under the food safety section:

Yi Lor

Yi Lor attended the Alzheimer's Association International Conference (AAIC) at Amsterdam, Netherlands in July 2023. The AAIC is a renowned conference where researchers from all over the world gather to meet and share their latest work in the understanding, prevention, and treatment of Alzheimer's disease and dementia. Yi shared his latest research on understanding how volunteering in late-life is associated with late-life cognitive function and decline, and how magnetic imaging resonance (MRI) brain measures are associated with cognitive decline in the KHANDLE and STAR study, two harmonized diverse cohorts of older adults ages 50 years or older. Additionally, Yi provided a research talk on subjective cognitive decline and objective measures of cognitive decline at AAIC. His research was featured as part of the AAIC and UC Davis Health media:  

Katie Lee

Katie Lee attended the 2023 National Institute of Antimicrobial Resistance Research and Education (NIAMRRE) Annual Conference held at the University of Florida, Gainesville, Florida. Katie presented a lighting talk titled “Impact of zinc supplementation on phenotypic antimicrobial resistance of fecal commensal bacteria from pre-weaned dairy calves”. Additionally, she received a first-place award for her poster presentation “Antimicrobial resistance in fecal commensals from cull dairy cattle in Central California”.

Shih-Yu Chen, PhD Candidate Attended the Conference of Research Workers in Animal Diseases (CRWAD) with her major professor, Dr. Gabriele Maier.





GGE Student_PS

Prior to graduation, Peter Sebastian, PhD, represented the UC Davis One Health Institute at the Sea Otter Conservation Workshop XIII held at the Seattle Aquarium March 19th. His presentation "Expansion of virulent Vibrio parahaemolyticus in humans and sea otters" utilized genomic epidemiology to identify pathogenic Vibrio parahaemolyticus strains shared by humans and sea otters as well as the virulence factors associated with disease.

GGE Graduates



Kyle Yomogida, PhD and Sophie Zhu, PhD
Graduated from the doctoral GGE program and both are now Center for Disease Control and Prevention Epidemic Intelligence Service (CDC EIS) officers (Class of 2023).

Sophie ZhuSophie Zhu attended the EcoHealth Alliance's EcoHealthNet workshop at George Mason University in June 2019. Students from across the world attended and learned about interdisciplinary topics such as GIS, compartmental modeling, and science communication. Sophie is also a research exchange intern with EpiCenter for Disease Dynamics this summer through the same program working under Dr. Johnson.

asdfaLaura Patterson - As a former small-scale, diversified farmer (e.g., flowers, vegetables) and goat dairy manager, my deep-rooted agricultural background informs my research as an epidemiology PhD candidate at the University of California, Davis. My dissertation focuses on evaluating the risk of disease transmission in the wildlife-livestock-human interface.

My interest in agriculture began as an Anthropology major at Grinnell College in Grinnell, Iowa, a liberal arts school rooted in the middle of farmland. Although agriculture degrees were not offered, our farming interest club brought speakers to campus and toured farms.
