  • Molecular Paleontology: Preservation and detection of original molecular fragments in well preserved fossil specimens

  • Molecular diagenesis and taphonomy: The examination of exceptionally well preserved fossils-those with soft tissues, color patterns, or original hard-part mineralogy or molecular signals preserved. Why are they preserved that way, and what are the biogeochemical conditions that led to such preservation?

Evolution of physiological and reproductive strategies in dinosaurs and their bird descendants. Were dinosaurs warm-blooded, cold-blooded or something in-between?  This includes paleohistology, sectioning bone from fossils to determine microstructure.


  • Astrobiology: Can we use the tools of molecular paleontology to detect biomarkers not only in fossils but also in extraterrestrial samples? Did life never evolve on other planets? Did it evolve then go extinct? Or is it thriving now?

  • I am recruiting graduate students and post-doctoral candidates who are interested in the chemistry, molecular biology, and immunological response of well preserved fossils, with the hope of identifying degree of preservation, recovery of original molecules, and the chemistry of diagenesis.   I seek students with strong backgrounds in analytical chemistry, molecular biology and immunology to contribute to the analyses of exceptionally preserved fossils and soft tissue remnants within bones from recent to Cretaceous specimens.
