I am interested in understanding the physiological, ecological and evolutionary factors contributing to behavioral variation, with an ultimate aim of increasing our understanding of how behavior evolves. My students and I use approaches from behavioral endocrinology, neuroendocrinology and physiological ecology to study the bases of behavior by studying animals both in the field and in the laboratory. Our research has been centered on questions related to the physiological bases of variation in aggressive and reproductive behavior, with two main foci: 1) endocrinology of male parental behavior, and 2) variation in androgen-glucocorticoid interactions in species with alternative male reproductive tactics, to better understand intraspecific variation in behavior and spermatogenesis. To date, our focus has been on steroid hormones because of their important role as chemical messengers that mediate behavioral, physiological and developmental processes. Interactions between the stress and reproductive endocrine axes are of particular interest because these axes mediate some of the major costs and benefits associated with male reproductive behavior.
