I consider myself to be an evolutionary palaeoecologist. The specific topics that interest me are the responses of organisms, particularly vertebrates and including humans, to climate change, such as range changes, and extinctions as well as macro- and micro-evolution. Projects include excavations, particularly at Trou Al'Wesse in Belgium, to better understand human and animal populations over the last 50 thousand years in relation to the climate and environmental change over that time. A particular focus has been on the former biogeography of taxa and the location of refugia for differently adapted taxa. How the latter affects the evolution and potential extinction of species and their genetic diversity forms part of that.
