RESEARCH INTEREST
My research focus is on establishing an accurate fossil record for the flowering plants that includes reliable floral evidence. This approach is unique and informative due to the nature of flowers, their information content and adaptive significance. Such a record has implications for molecular evolution, hyper radiations characteristic of the angiosperms and for evaluating ecological-evolutionary hypotheses invoked to explain angiosperm dominance of modern ecosystems. Such research has implications for systematics/systematics methodologies and for the evaluation of molecular clock based timing models.
