TEACHING AND RESEARCH AREAS

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?

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?
