I investigate why our bodies are not perfect, and how that is affected by sex. Given natural selection always increases their quality, why aren’t our bodies much better than they are? Furthermore, does the evolution of genes involved in sexed bodies and their organization limit the overall quality of male and female bodies?

Specifically, I study the interaction between selection interference, gene expression and sexual dimorphism. Selection interference is a phenomenon arising from natural selection acting on sites that are inherited together, such as linked on a chromosome. Selection interference, as the name suggests, hinders the efficacy of selection and causes a genetic load in the genome that could affect organismal fitness. This is a fascinating effect arising from an inherent feature of our system of inheritance! By using population genetic techniques, I hope to understand how sexed-bodies and genetic sex come together to influence fitness, demography and genome evolution.

I received a PhD in Evolutionary Genomics, working out of the lab of Dr. Stephen I Wright at the University of Toronto. My CV is available here (updated Apr. 24th, 2019).

Some of the scripts I’ve written are available from my GitHub here
