My research uses a one health approach to understand the role of host physiology and immunology in disease transmission, primarily in free-ranging wildlife species. I am also interested in identifying new parasite species in wildlife, understanding the impact of disease and parasites on wild hosts, as well as understanding interactions between parasites and diseases within these hosts. My work spans numerous species and landscapes, including voles in Oregon, hemorrhagic diseases in Uganda, bighorn sheep disease in California and Oregon, African buffalo diseases in South Africa and sea lion parasitism in the Pacific Ocean. I also am interested in using eDNA to detect pathogens and parasite patterns in the aquatic landscapes throughout the Willamette Valley.
