In addition to my work in the field, my research projects all have significant laboratory components. In much of my research, I use non-invasively collected urine and fecal samples to measure reproductive and stress hormone concentrations and markers of energetic status with radioiummuoassays (RIA) and enzymeimmunoassays (EIA) in a variety of species. More recently, I have been analyzing DNA and RNA to determine demographic information such as paternity. My lab work also includes studies in the areas of disease ecology and the gut microbiome.
