Research Interests
My research projects focus on the sedimentology and sequence stratigraphy of carbonate rocks. My most recent projects are collaborative studies with Peter Sheehan (Milwaukee Public Museum) of Upper Ordovician-Lower Silurian facies, sequences and communities of the Great Basin and Estonia. We are currently developing a project to look at the sedimentological and paleontological changes in the east Baltic Middle Ordovician-Lower Silurian section as Baltica moved from sub-polar to tropic settings. This interval is of particular interest because it includes the Great Ordovician Radiation, the end Ordovician extinctions, and the Early Silurian recovery. Peter and I are working with Leo Ainsaar (Tartu University), Linda Hints, Olle Hints, Jaak Nõlvak (Institute of Geology, Tallinn Technical University), Andri Dronov (Moscow State University), and Seth Finnegan (University of California) on this project. Last summer, Seth and I traveled to Estonia to meet with our colleagues to examine outcrops and cores to understand the basic stratigraphy and facies relations (and plan our grant submission).
