Dissertation Research
In my dissertation work, I examined the patterns of local adaptation in a marine fish at a fine spatial scale and identified the genetic mechanisms that contribute to several life history traits. I am interested in the mechanisms of sex determination in fishes and I focused on a species with both genetic and temperature-dependent sex determination. Additionally, I investigated how local adaptation in the form of sex determination mediates the response to environmental endocrine disruptors. I also addressed the mechanisms contributing to differences in intrinsic growth rates among populations of fish over a steep environmental cline and how these mechanisms of growth were altered in response to strong artificial selection.
