I am interested in how endocrine systems work to modulate how animals interact with a dynamic environment. Specifically, I’m interested in studying how hormonal systems help animals to cope with and prepare for major life changes, like development, stress and reproduction, and the interaction of hormones, behavior and the immune system.

Projects that students in my lab are currently working on include:

  • Studying the impact of stress and reproductive hormones on sickness behavior and immunocompetence in house sparrows
  • Studying the interactions between parenting, health, and hormones like corticosterone and prolactin in breeding eastern bluebirds (with Dr. Judy Guinan)
  • Developing measures of bacterial immunocomptence that can be used across a wide range of species (with Dr. Joy Caughron)
  • Exploring how major royal jelly proteins modulate growth, behavior and reproduction in insects and other arthropods

Some of my past research has explored the interaction of stimuli traits, sex differences and stress state on neophobia in songbirds, differences in neuroendocrinology and receptor dynamics in native and invasive songbirds in Tibet, variation in hormone receptor patterns in expanding populations of songbirds in the Pacific Northwest, and species variation in natural fear and stress responses in old world monkeys. In my lab we use a wide range of techniques to study and experimentally manipulate physiology, including ELISA hormone assays, automated behavioral tracking systems, histology, immune assays, neurohormonal modulation, and in situ hybridization. We also spend a lot of time in the field catching birds in big nets and a lot of time in the lab working with bugs in tanks.
