Research Focus

Dr. Smith's research program uses One Health approaches to investigate the epidemiology and transmission dynamics of zoonotic pathogens locally in California as well as internationally at multiple project sites in Africa and Asia. As a molecular epidemiologist working at the interfaces of humans, animals, and their shared environments, waterborne fecal pathogens as well as milk- and airborne transmitted zoonotic agents are of particular interest when considering individual and population health issues.
