My research interests center on vertebrate taphonomy, ichnology, paleopathology, and paleoecology. In particular, I study bone surface modifications generated under modern and experimental conditions to better understand the processes which left similar traces on bone in the fossil record.

  My current projects include:

  • Testing methods for applying these modern analogies in a deep time perspective.
  • Interpreting trophic interactions, behavior, and diet of different archosaurian groups.
  • Identifying and differentiating historically understudied traces and pathologies, such as bite marks, shell disease, and plant or fungi mediated damage to bone.
