I earned a B.S. in Zoology and the Honors Program from the University of Wyoming in 2011. While at Wyoming, I designed and conducted an independent research project documenting poorly known breeding behaviors of common nighthawks under the direction of Dr. Anna Chalfoun. In addition to my independent research, I have been fortunate to work on projects in diverse systems including exploring golden-winged warbler demography in both Minnesota and Manitoba, studying the impacts of energy development on sagebrush-obligate songbirds in Wyoming, studying migratory behaviors of northern saw-whet owls in Pennsylvania, monitoring spring migration along the Gulf Coast of Texas, and studying cooperative breeding behaviors and responses of habitat destruction on the endangered white-breasted thrasher in St. Lucia.
My research interests generally lie within the field of population ecology and management. I am especially interested in uncovering factors influencing the long term population trends in bird species and using a full understanding of a species' life-cycle ecology to develop efficient and effective management strategies. In 2013, I joined Dr. David Andersen's lab at the University of Minnesota as a M.S. student where I contributed to the investigation of migratory connectivity among golden-winged warbler populations under the co-advisory of Dr. Henry Streby. As a Ph.D. student at the University of Toledo, I will be working with a range-wide dataset from the hybridizing Vermivora species complex, including data on migration ecology and connectivity, plumage color and pattern, song variation, immune function, telomere length, and genetic variability in hundreds of birds we and our collaborators sampled in recent years. I will also be working closely with the Black Swamp Bird Observatory and helping Dr. Streby establish his research lab in the northwest Ohio warbler migration mecca.
