  • BIO 188. Evolution. General survey of evolutionary processes: mechanisms of evolutionary change, adaptation and history of life. Designed for biological sciences majors. Lecture three hours. Prerequisite: BIO 184 or instructor permission. Graded: Graded Student. Units: 3.0
  • BIO 282. Evolution. Process of evolution throughout the taxonomic hierarchy and factors responsible for the generation of variability of the gene, cell, organism and population levels are explored through lectures, text readings and a survey of current periodical literature.

Research Interests

My work focuses on the evolutionary genetics of sexual selection (the outcome of mate choice and competition over mates). With collaborators, I have conducted experiments estimating costs and benefits of sexual selection in Drosophila melanogaster and have proposed a general hypothesis for the evolution of courtship, via genes that act in a sexually antagonistic manner (good for one sex but at the expense of the other) see, Chase-away, below. Specifically, males sometimes appear to exploit female sensory systems in a way that is analogous to manipulative advertising (e.g., through increased volume or vivid coloration of an ornament), at a cost to females. This selects those females who have reduced sensitivity to those ornaments. This counter selects those males who have even more stimulating ornaments. Current interests center on evaluating the Chase-away hypothesis through experimentation and literature analysis. Students are welcome to inquire about research opportunities.
