Academic Title(s)

  • Ingalls-Brown Professor of Anatomy


I study fossil whales in order to answer questions about their evolution, in particular about how whales originated from land animals. I also study modern bowhead and beluga whales to learn about their biology and its implications for the management and conservation of these Arctic species. I use anatomical, histological, and embryological samples, collected by doing field work in India and Alaska.
