Sarah C. Jones Sarah joined the lab as a PhD student in the fall semester, 2010. Her dissertation focuses on the physiological basis of inter-individual and intersexual variation in aggressive behavior. The despotic social system and "role-reversed" sex differences characteristic of spotted hyenas make them a rich new model for the study of the neuroendocrine mediation of sex differences in mammalian aggression. Sarah also has a strong interest in education. Her education experience includes serving several semesters as a teaching assistant, teaching our study abroad (the Behavioral Ecology of African mammals) twice, spending a year participating in the GK-12 fellowship program at the Kellogg Biological Station, working with the MSU museum, and serving as an Inside Teaching MSU fellow.
