Research interests: My research integrates data from living plants and the fossil record to address questions on plant evolution, phylogeny, and diversity through time. Current research is focused on understanding Indian floras at the Cretaceous-Paleogene boundary, the role of India in plant radiations, and macroevolutionary patterns in palms (family Arecaceae) using phylogenetic and quantitative methods that incorporate the fossil record. Other research interests include the evolution of leaves and rooting systems among vascular plants, the role of auxin in plant development and morphological evolution, and phylogenetic relationships among living and extinct plant lineages.
