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.

Eli Strauss publishes two awesome papers on hyena dominance, then defends his dissertation
Senior graduate student Eli D. Strauss published two recent papers on hyena dominance hierarchies. One paper appeared in the April 2019 issue of Journal of Animal Ecology, and the other appeared in the 30 April, 2019 issue of Proceedings of the National Academy of Science (PNAS). The latter paper made the issue cover, and is discussed in a commentary on hyena dynasties by Joan Silk. These papers represent two of Eli’s dissertation chapters. Congratulations to Eli!
