Research Interests

My research interests fall at the interface of wildlife epidemiology and spatial ecology, including detailed mechanistic studies of diversity-disease relationships, ecology of host microbiome, host-pathogen responses to abiotic factors, and the connectivity and dispersal of animal populations. I build spatial models and conduct both field and laboratory experiments to understand the biotic and abiotic mechanisms underlying the distribution of wildlife from local to global scales, with the overarching goal of diagnosing patterns of biodiversity threats and loss. My research is divided into four broad areas of investigation: 1) disease ecology, 2) spatial analyses of genotypes and phenotypes, 3) effects of habitat alteration on population demographics, and 4) application of ecological findings to conservation.
