Palynological Research at LSU




          You might think of pollen as the main cause of your allergies and museum collections as a symbol of the past, but Associate
          Professor and Curator Sophie Warnys research and the collections she curates are all but passé.  Her research group focuses on
          the many applications of pollen.  In addition to the classical approach of using fossils of pollen and spores to date oil-bearing
          sequences (three of her former students were hired as biostratigraphers in the oil and gas industry), she uses these fossils to
          reconstruct past climate.  Her research group found and dated some of the last forests that existed in Antarctica, and this research
          was published in journals such as Geology, the Proceedings of the National Academy of Science, and Nature Geosciences and was
          funded by the NSF CAREER program.  Her group also lead one of the first measure of carbon isotope signal in single pollen grains,
          allowing to reconstruct past precipitation levels in the Antarctic at a time when the first Antarctic ice sheets were forming.  This
          latest attempt allowed one of her doctoral students, Dr. Kate Griener (now at BHP Billiton) to win the 2015 LSU College of Science
          dissertation award.  Finally, one of their latest endeavors is to use pollen, pollent print and museum collection in trace evidence
          evidence research to help in forensic cases.  Her new approach was discussed in the journal Science in 2013 and Dr. Warny and LSU
          submitted a pattent for a new method of pollen print collection. The patent is under review.
