Position: Postdoctoral Research Fellow
My main research interest is in understanding the genetic architecture of quantitative traits, particularly traits under sexual selection. Why is there so much genetic variation underlying these traits? What are the evolutionary forces responsible for maintaining such high levels of genetic variation? Is variation predominantly caused by deleterious alleles being removed by selection, or is there lots of adaptive potential? I have explored these questions in a sexual selection context using biometric and molecular approaches. Currently, I am exploring how the distribution of genetic variation in multivariate trait space is affected by mutation and selection (utilising the animal model framework). I have worked with a range of model insects, but have primarily worked with Drosophila. My favourite fruit is the mango.
