My research at the University of California, Riverside focused on the neuroendocrinology of parental care, specifically paternal care in mammals. Using a biparental mammalian model species, the California mouse, I investigated the neural plasticity that underlies their shift in infant-directed behavior, from indifferent or aggressive to robustly paternal, that occurs in virgin male California mice when they become fathers. My approach to teaching uses active learnings and emphasizes the utility of course material.
