As a scientist, I have always been interested in how animals use and acquire space where they live and breed. Since most animals must compete for space with others of their species, my interest has led naturally to study of animal aggression and competition. My PhD focused on how the social rank of a white-throated sparrow (Zonotrichia albicollis) in a winter dominance hierarchy affected its local movements and likelihood of survival. I have also investigated aggression and breeding among male stripe-backed wrens (Campylorhynchus nuchalis) in Venezuela. But for the past 22 years, I have examined territory defense, territory settlement, and breeding behavior of loons. My CV gives specific details regarding my professional career.
I am a professor of biology at Chapman University in Orange, California.
