I am interested in human (paleo)ecology from a deep time perspective. My primary
research focuses on reconstructing selective pressures for the emergence of genus Homo
and dispersal from Africa and the connections of human evolution to global climatic
change. I also study various dietary strategies of human groups to island ecosystems. I
integrate stable isotopic methods with zooarchaeology, human osteology, sedimentology,
and paleogeography.
