I am interested in conservation biology and the management of small avian populations in endangered species recovery programs. My research focuses on evaluating inbreeding depression and exploring the concept of ‘adaptation to captivity’ in the federally endangered Attwater’s prairie-chicken (Tympanuchus cupido attwateri) in an effort to better understand and improve factors affecting the survival of reintroduced individuals. I am using molecular methods to verify the existing pedigree and evaluate the consequences of potential errors. The second component of my research uses a variety of immune-related measures to evaluate ‘immunity’ among individuals in the captive-release program and determine if immune response is correlated to genetics or survival post release.

Broadly, I aim to contribute to the mitigation of our species’ negative impact on Earth’s biodiversity through education and applied research. My graduate research focuses on identifying factors that may influence avian population viability, specifically: pollution and habitat fragmentation. Initial research (for MS degree) quantified mercury levels in avian species at Arctic, Temperate and Sub-Antarctic latitudes to provide baseline environmental mercury values across differing trophic levels and proxomity to potential point sources. More recently, I am investigating population connectivity among Greater Sage Grouse (Centrocercus urophasianus) populations in Northwestern Wyoming using population genetic-based analyses. The results of this work will help to inform conservation and management decisions of Sage Grouse populations in Wyoming.
