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?
