Big Questions in Paleontology – The Paleosynthesis Project

Research Interests

  • Predator-prey interactions in the fossil record with a focus on mollusks and factors biasing their preservation
  • Application of the fossil record to the understanding of the modern biodiversity crisis, particularly to assess the effects of human actions on ecosystems (i.e., conservation paleobiology)
  • In each of these research areas, I am also very interested in developing new analytical approaches, and integrating approaches from other fields, to increase the utility and transference of paleontological data
