I received my PhD from Oregon State University working on postcopulatory sexual selection and sexual conflict in garter snakes. I am also very interested in the energetics of courtship and mating and during my first postdoc started to think more holistically about how energy allocation toward sexual competition and reproduction more generally might affect reproductive tactics and other life history traits such as life span. In my current postdoc at the University of Sydney working on sperm-egg interactions in cane toads, I have come to appreciate how geographic variation across a species' range can be harnessed for intraspecific comparative studies. These experiences have lead to my current fascination with environmental drivers of geographic variation in, and the physiological underpinnings of sexual selected and life history traits.
