Ashley Contreras

Major: Ecology, Evolution & Biology
Department: College of Biological Sciences
Level of Study: Bachelor’s degree
Campus: UC Davis
Host Site and Mentor: UC ANR, Eric Middleton
Ashley Contreras is a senior at UC Davis pursuing a bachelor’s degree in Ecology, Evolution & Biology with a minor in Public Health. They have a research background in plant, fish, and mammal health. Ashley's current research at the UC Davis One Health Institute involves understanding infectious diseases, where she is exploring the interface of animals, people, plants, and the environment to solve complex problems that impact health and conservation around the world. She aspires to become an epidemiologist specializing in marine ecosystems to contribute to the understanding and management of infectious diseases in this critical and fragile environment. Ashley was matched with Eric Middleton of UC ANR to conduct trials and experiments on Agave mites, which are significant pests in commercial nursery production in San Diego County. The study aims to understand the spread of diseases caused by these mites and their impact on agave. She is excited to continue her academic and research pursuits and hopes to make a positive impact on global health and conservation efforts.
