RESEARCH INTEREST AND LAB PROJECTS

  • Paleopathology and Vertebrate Paleontology: I am interested in the study of fossil bones with modifications indicative of lesions. Currently, I am part of a team examining a monodominant Cretaceous Edmontosaurus annectens bonebed (Lance Formation, WY). Examples of lesions observed: healed fractures, tooth traces, degenerative joint diseases, infections and neoplasm. The degree of the bone modification associated with lesions potentially suggests premortem, perimortem and/or postmortem events. This study enriches our understanding of inter-intraspecific interactions, animal behavior, biomechanics, animal’s living conditions and Earth history.
  • Molecular Paleontology: I am also collaborating in the study of microstructure and biomolecules preservation in fossil bones. This study potentially contributes to our understanding of taphonomic processes associated with examined bones such as burial processes and conditions necessary for the preservation of the remains and fossilization.
  • Other Interests: effects of biomechanics in bones, comparative anatomy including variations (normal and pathological) observed in skeletal remains.
