Within the past fifteen years, remarkable advances in the study of the phylogenetic relationships of plants have provided the raw materials for critical studies of character evolution. Armed with hypotheses of relationships among organisms, I seek to explore how patterns of morphology, anatomy and cell biology have evolved through the modification of developmental processes. My work is primarily focused on the origin and subsequent diversification of flowering plants, Darwin's "abominable mystery." - ## People Categories [Arnold Arboretum](/people-categories/arnold-arboretum) [Organismic & Evolutionary Biology](/people-categories/organismic-evolutionary-biology)
