Evolutionary genomics of sex chromosomes


We are interested in understanding how sex chromosomes have repeatedly evolved across the tree of life. We use stickleback fish as a model system to explore the evolutionary forces that shape sex chromosomes at the earliest stages of evolution.  We combine classical genetics, molecular genetics, and bioinformatic approaches to understand key processes in the formation of sex chromosomes, including the regulation of meiotic recombination and the genetics of sex determination.
