Welcome to my research page at Oregon State University

I am an evolutionary geneticist interested in the processes that lead to genomic and phenotypic divergence among natural populations.

Through the combined actions of natural selection, mutation, and genetic drift, geographic isolation among populations promotes the evolution of unique adaptations, as well as the formation of new species. These processes are particularly interesting in marine systems because of their unique ecological and physiological challenges, and because their populations have the potential to remain homogeneous through the exchange of genes over long distances. 

General questions that motivate my work include:

  1. What genetic incompatibilities prevent certain populations from interbreeding?

  2. Do adaptations evolve via repeated genomic changes in isolated populations?

  3. What novel genetic interactions are formed during adaptation to new environments?

In another line of research, I examine the relationships among sexual selection, mating systems, and intrafamilial conflicts.  These connections are key to elucidating the evolution of reproductive behaviors in animals, such as promiscuity, parental care, and filial cannibalism. 

I employ copepods and sea spiders as primary study systems, but I have worked on a variety of marine and freshwater species to address diverse questions in evolutionary biology.
