Darrell is a Regents’ Professor in the School of Earth and Sustainability at Northern Arizona University. He has been researching the Quaternary geology and paleoclimatology of Alaska for over 30 years. He has a special interest in geochronology and in coordinating large collaborative science synthesis projects.
His research group studies geologic records of environmental changes to understand how the Earth system responds to natural and anthropogenic forcings on millennial time scales. It focuses on lake sediments from Alaska, geochronology, and proxy climate syntheses.
