Research Areas

Behavioral endocrinology, behavioral ecology, and conservation biology of wild social mammals.

Currently, I am investigating the endocrine correlates and fitness consequences of variation in the mother-offspring relationship in two species of wild monkeys in Africa (i.e., baboons in Kenya and gelada monkeys in Ethiopia). I am also investigating the development of sex differences in behavior and ecology, and in the adaptive significance of male-female bonds and dominance in wild baboons and geladas. Finally, my collaborators and I are studying the ranging ecology and conservation biology of a population of wild geladas inhabiting an alpine grassland (called Guassa) that has been conserved by one of the oldest surviving indigenous conservation initiatives on the African continent.
