 I obtained my PhD from the University of the Witwatersrand, where I worked on sexual selection and speciation in Lake Malawi cichlids. I then went on to complete a post-doctoral fellowship at Bowling Green State University in the USA, working on acoustic signalling in bladder grasshoppers. On returning to South Africa, I joined the University of the Western Cape, first as a temporary lecturer, and later as a permanent member of staff.
