Current Research Program:

The purpose of my research program is to use integrated genetic, ecological and phylogenetic approaches to study social evolution across all levels in the hierarchy of life, from genes, to cells, to organisms, to social systems, and to the brain.

In my lab we currently focus on several of the outstanding questions in evolutionary biology, including the evolution of social behaviour, the evolution of human health and disease, the evolution of placentation and maternal-fetal conflict, the evolution of trophic interactions, and the roles of genetics, ecology and geography in speciation and adaptive radiation.

We are studying the evolutionary biology of human health and disease by analyzing the evolutionary-genetic bases of the major human diseases that are mediated in part by genomic conflicts: placental disorders, cancer, autism, and schizophrenia.

We are analyzing the genetics, ecology and geography of speciation using species of walking-sticks in the genus Timema, which exhibit a set of characteristics, including crypsis, genetically-based color polymorphisms, variable degrees of host-plant specificity, and obligate and facultative parthenogenesis, that make them ideal for a combined phylogenetic and ecological attack on these questions. These studies are being conducted in collaboration with Cris Sandoval, Tanja Schwander, and Patrik Nosil.  

We are studying the evolution of maternal-fetal conflict over resources in mammals, via phylogenetic comparative analyses of placental and maternal traits, and connecting placental invasiveness with aspects of mammalian life history and encephalization.
