My major teaching effort is in Human Gross Anatomy at the Washington University School of Medicine. I also periodically teach a course in quantitative genetics and evolution.
My research centers on evolutionary quantitative genetics and morphology. The research in quantitative genetics concerns the development and genetic constraints imposed on the rate and direction of evolution by heritable variation patterns and the evolution of genetic variation patterns themselves. Current and planned future projects in this area involve both empirical and theoretical studies of the evolution of genetic correlations, maternal effects and kin selection, the genetics of somatic growth, the inheritance of brain surface morphology, and the heritability, genetic correlation and evolution of primate craniofacial morphology. We are currently studying the morphological genetics and systematics of New World Monkey species, specifically tamarins and marmosets. This study involves the reconstruction of selection acting on craniofacial morphology. The tamarins and marmosets include several endangered species and we are developing a quantitative genetic approach to captive population genetic surveys and management.
