Dr. Grissino-Mayer's interests concern the use of tree-ring data to better understand past environments. He has been involved in tree-ring research for nearly 25 years, has published over 50 articles, reviewed over 100 manuscripts for over 40 journals, obtained over $2 million in research funding, developed software used worldwide, and has created numerous databases used by dendrochronologists. His research has focused primarily on developing long-term tree-ring records, reconstructing past climate, reconstructing past wildfire activity, and analyzing the association between wildfires and climate. He's conducted research in Canada, the Bahamas, the Dominican Republic, England, Arizona, New Mexico, Virginia, Oregon, Montana, Idaho, Tennessee, North Carolina, South Carolina, Kentucky, Georgia, Florida, Minnesota, California, Colorado, and New Hampshire. He and the students in his laboratory have been featured in television documentaries that have aired on the History Channel, Learning Channel, National Geographic Channel, Discovery Channel, Weather Channel, and Court TV. In 2007, his research was chosen by the Weather Channel as one of the "100 Biggest Moments in Weather History." He's held numerous professional positions, including Chair of the International Tree-Ring Data Bank, Secretary of the Tree-Ring Society, Associate Editor of three journals, and Board Member of the International Multiproxy Paleofire Database.
