RESEARCH AND TEACHING INTERESTS:
My research uses field and molecular techniques to explore the evolution of ecologically
important traits in birds. In the field, I combine observational and experimental
work on color-banded individuals to describe the costs and benefits of avian life
history decisions. In the laboratory, I use hypervariable genetic markers to describe
patterns of gene exchange within and among populations. Current projects with Savannah
Sparrows (Passerculus sandwichensis) and Common Yellowthroats (Geothlypis trichas)
explore the adaptive significance of avian reproductive behavior and signaling systems.
Most recently, my work has focused on the evolution of male and female plumage displays,
and I am currently exploring the interrelationship between cell-level processes (telomere
dynamics, oxidative stress), carotenoid-based plumage ornaments, and the fecundity
and survivorship of adults.
Undergraduates participate in both the field and laboratory components of my research, and I view as essential the active learning that student-faculty collaboration engenders in its participants. Science is not a body of knowledge to be passively absorbed by students but a process of active inquiry that is most effectively taught by doing. In my courses, students engage in all aspects of scientific research: they work independently or in small groups to generate research questions, to devise methods of evaluating their hypotheses, and to communicate their results to the larger community. This approach to science education demands much of students, but it also captures the excitement and challenge of scientific inquiry.
