Dr. Grissino-Mayer splits time between being a climatologist and being a biogeographer, and his primary research interests include the reconstruction of past environments using information from tree-ring data (dendrochronology). His accomplishments include (1) the development of a 2,200 year long reconstruction of annual precipitation for the American Southwest, (2) the development of numerous reconstructions of fire regimes in both in the western and eastern U.S., (3) and using dendrochronology to help historical archaeologists more accurately chronicle cultural history.
