In a broad sense, I am interested in the evolutionary and landscape forces that shape population differentiation. Of particular interest to me are 1) describing genetically and morphologically distinct populations, 2) identifying specific landscape features, life history characteristics, and historic geological factors that influence population structure and, 3) understanding how distinct populations within migratory populations differentially utilize landscapes. To address these questions I study raptor populations using a variety of tools including field mark-recapture methods, molecular genetics, and morphometric analyses.
- Population genetics and historical demography of Red-shouldered Hawks (Buteo lineatus)
- Population genetics and conservation of Great Gray Owls (Strix nebulosa) in the Yosemite region
- Migration timing and behavior of distinct Red-tailed Hawk (Buteo jamaicensis) populations along the Pacific coast
- Population genetics and phylogenetic relationships of B. j. calurus, B. j. borealis, and B. j. harlani
- Population genetic analysis of North American of Swainson's Hawks (Buteo swainsonii)
- Prevalence of West Nile Virus antibodies in wild raptor population
- Population Genetics of Sharp-shinned Hawks (Accipiter striatus) in North America
