My research interests are centered on evolutionary processes and the estimation of evolutionary trees. Methodologically, I am most committed to the use of maximum likelihood and approaches that can be justified in a likelihood framework. In terms of data, I have worked with both morphological and molecular sequence data, but mostly with the latter. I am interested in animal phylogeny in general, but have been most involved with questions about mammalian evolution, particularly the biology and relationships of ‘insectivores’, a group whose integrity has always been problematic . Many of my research students have worked on insectivores in one way or another. The selected publications below give an idea of some evolutionary interests over four decades.
