Research Focus

The development and application of One Health methods for the advancement of global health problem solving, especially the understanding of emerging infectious diseases and the conservation of threatened species and ecosysytems. Research has focused on the emergences and impacts of zoonotic diseases and toxins at the animal-human-environment interface. Three major areas of emphasis: One Health risk assessments, emerging pathogen diagnostics, and ecology of zoonotic diseases and their impact on wildlife conservation and public health.

Specialty Focus

Epidemiology, One Health, Pathogen Pollution, Marine and Coastal Conservation, Emerging Infectious Diseases, Land Use Change, Climate Variability, Wildlife Health
