Dr. Sherwood is a biological anthropologist interested in brain evolution and its behavioral correlates in primates and other mammals. Dr. Sherwood's comparative neuroanatomical research has focused on issues related to allometric scaling at macro- and microanatomical levels, brain asymmetry and behavioral lateralization, evolutionary changes in human language area homologues, the anatomical basis of phylogenetic differences in orofacial motor capacities, and neurochemical substrates of cognitive differences among primate species.
