Research Interests

Environmental influences on life history patterns

Research Summary

 

A central focus of my research program is in understanding how environmental factors shape life history patterns, particularly reproduction. My past research has included work with mammals and has included research aimed at understanding how social and ecological variation influence patterns of survival and reproduction in spotted hyenas. However, my research now focuses on using songbirds as a model to study how animals time events in their annual cycles. Reproduction and migration are important events in the annual cycle of many animals, and a major area of emphasis in my research is on understanding how birds time these events. This work examines the role of environmental cues (e.g., photoperiod, food availability, social cues) in reproductive and migratory timing, as well as the endocrine and neuroendocrine mechanisms by which environmental cues are transduced to influence behavior and physiology.
