Vertebrate paleontologist with interests at the interface of morphology, evolution, and development.
My interests lie in patterns of morphological diversity and how they arise during the embryological development of the individual and during the evolution of lineages over geologic time. Most of my projects examine serially homologous structures, such as vertebrae and ribs, in mammals. These structures are repeated segmentally but show regional differentiation when they interact and articulate with structures with different developmental patterning. Species with highly derived morphologies that appear to “break the rules” of mammalian morphology, such manatees, tree sloths, and whales intrigue me particularly.
I retired from teaching at Wellesley in December 2020, but multiple research projects are in progress. Here are some of my recent publications:
