I am interested in the evolution of mating strategies and of mating systems. One way that females may enhance their evolutionary fitness is by influencing fertilization. It is known that females can influence the outcome of sperm competition and there is evidence that they may also have the ability to influence the sexes of their offspring. I am currently investigating the possibility of sex ratio biasing of egg clutches in the sierra dome spider in response to male quality. Female sierra dome spiders often die before oviposition. Because sexually competitive male sierra dome spiders have shorter lifespans, it may benefit females to bias the sex ratio of their clutches toward males when they mate with sexually competitive males because daughters sired by these males may be more likely to die before they reproduce.

Research Interests: desert fishes often face extreme conditions, particularly in small isolated habitats with widely ranging temperatures, salinity, and dissolved oxygen. Currently, I am investigating how ecological variables influence life history and reproductive investment of desert fishes, particularly Gambusia nobilis. As part of this study, I am documenting morphological variation between populations and factors that may influence this variation. Additionally, I am interested in changes in population structure over time, particularly shifts in gender, size, and age frequency distributions.

I am interested in mating behaviors across species. In many different taxa, animals have evolved a few general mating tactics (polygyny, polyandry, monogamy) in response to resource availability and distribution. As global climate change is now a prevalent issue, it would be interesting to see how animals are responding to changes in resources and how their fitness is affected by these changes. Also, I am interested in the cellular and molecular underpinnings of behavior, from development and on through an organism's life.

General Interests: behavioral ecology, evolutionary biology. To address my primary interest in sexual selection, my work spans co-adapted gene complexes; sympatric speciation; olfactory sensing of immune system products; the evolution of monogamy in birds; honest signaling in humans, and the role of humor in human mating. Additionally, I am interested in how behavioral and evolutionary theory can be used to inform governmental policy.
