Mazet is a leader in the field of One Health and is active in international research programs, most notably in relation to disease transmission among wildlife, domestic animals, and people and the ecological drivers of disease emergence.[1] One Health is the collaborative effort across multiple disciplines (veterinary, human medical, environmental, etc.) to attain optimal health for animals, people, and the environment. As a member of the National Academy of Medicine, Mazet also chairs the National Academies’ One Health Action Collaborative and serves on the Forum for Microbial Threats.[2]

She is the Global Director of the PREDICT Project, a more than $200 million viral emergence early-warning project that has been developed with the United States Agency for International Development’s (USAID) Emerging Pandemic Threats Program.

Mazet was born and raised in Marin County, California and currently lives both there and in Davis, California, USA with her husband. She has two daughters.

Education and early careerEdit

Mazet earned her Bachelor of Science in Veterinary Medicine from the University of California, Davis in 1990 and her Master of Preventive Veterinary Medicine in Wildlife and Infectious Disease and her Doctor of Veterinary Medicine in 1992. In 1996, she completed a PhD in epidemiology, expanding her training across human and animal species divides.[3]

Mazet worked as a wildlife veterinarian for the California Department of Fish and Wildlife where she was instrumental in the development of California’s Oiled Wildlife Care Network (OWCN).[4] While working as an oil spill responder, she advanced the collaborative Network, making it a model for wildlife emergency management systems worldwide, and remains a consulting expert on animal emergency preparedness and response.

She joined the faculty of the UC Davis School of Veterinary Medicine in 1998 and became Co-director of the fledgling Wildlife Health Center and moved the headquarters of the OWCN to the university.

In 2009, she became Executive Director of the newly formed UC Davis One Health Institute, which is home to programs and projects that do work around the world, including the Karen C. Drayer Wildlife Health Center, PREDICT Project, Gorilla Doctors, SeaDoc Society, EpiCenter for Disease Dynamics and the California Raptor Center.

Viral discovery and pandemic preparednessEdit

Mazet is currently the Principal Investigator and Global Director of USAID’s PREDICT Project, which works in more than 30 countries to build capacity to develop surveillance systems and complete the necessary research to halt the next pandemic, like influenza, SARS, Ebola, and HIV.[5] With these projects and others as a research foundation, she has served as the mentor for over 70 graduate student and postdoctoral trainees. She also serves on the National Academies of Science, Engineering & Medicine Forum on Microbial Threats. She also co-authored the following recent publications: The discovery of Bombali virus adds further support for bats as hosts of ebolaviruses (Nature Microbiology) and The Global Virome Project (Science).
