Dr. Cole Edwards

Dr. Edwards jointed the department in 2016.  His research focuses on the interaction between the biosphere and environment and their evolution throughout Earth history, as recorded in the sedimentary record.  He seeks to find new ways of integrating sedimentological, geochemical proxies of paleoenvironmental conditions, and paleontological data to better understand key intervals in Earth history.  His research interests involve several sub-disciplines of geologic study, such as sedimentology, diagenesis, isotope geochemistry, chemostratigraphy, and paleoclimatology. 

Much of Dr. Edwards’s research focuses on carbonate rocks, which form through interaction of biological and geological systems.  Geochemical data extracted from carbonate sediments can be used to reconstruct environmental conditions of ancient seas and climates to provide information about likely influences on the biosphere.  His more recent research uses this approach to study the potential causes of the largest biodiversification event in the Phanerozoic by looking at Ordovician carbonates from across the USA (Nevada, Utah, Oklahoma, Virginia, Maryland, etc).
