Research Interests

My broad research interests relate to understanding the processes underlying nervous system evolution. In the Peichel Lab, I am currently investigating the genetic basis for divergence in a courtship display behavior between populations of stickleback from different lakes in British Columbia. I plan to use genetic linkage analysis to uncover regions of the genome that are associated with differences in courtship display and to identify the particular genes that underlie phenotype-genotype associations. Eventually, I hope to link specific genetic changes to changes in the development, structure, and/or function of the nervous system.

As a complement to the unbiased genetic approach to the study of nervous system evolution that I'm using in sticklebacks, I have also applied a more targeted approach to this problem. As a Grass Fellow at the Marine Biological Laboratory in Woods Hole, MA, I identified differences in startle responses among species of pufferfish. The circuitry underlying startle responses in fish is well-characterized, and will allow for a direct examination of how changes in this circuitry correlate with the changes in behavior exhibited by different puffers.
