My research focuses on the role that climate has played in the long-term evolution of Neotropical forests, primarily through the reconstruction of paleoecological and macroevolutionary trends of individual plant clades from the fossil pollen record. Despite its modest standing in the popular imagination, fossil pollen is an ideal source for paleoecological information. The palynological record is one of the most ubiquitous terrestrial fossil records. Pollen and spores are abundant, resist degradation, and are found at the bottom of most water bodies, past or present. For this reason, the palynological record is expressly suited for quantitative analyses of continuous, long-term trends in plant ecology and evolution, including time-series analysis of origination and extinction rates, migration, and functional morphological evolution.
