Research in my laboratory focuses on mammalian behavioral development, its physiological substrates, the socio-ecological forces shaping it, and its evolution. My students and I are currently investigating how social, ecological, and endocrine variables interact during an individual's early development to influence its subsequent behavior, survival and reproductive success as an adult.
