I am Senior Curator Emeritus and Editor, Botanical Review at the New York Botanical Garden.
My major research interests in the past few years have focused upon the evolution and classification of the Cycadales (cycads) and their placement in seed plant phylogeny. To this end I am conducting research on various facets of the biology of the Cycadales and Gnetales. These facets include reproductive biology, anatomy, cytology, molecular systematics, as well as taxonomic monographs and treatments of these groups for various floras being prepared for the neotropics. These research interests are being pursued by an active field program, particularly in the neotropics, to survey population sizes and demographics, to understand phenology, to study the recently discovered insect pollination biology of cycads and Gnetum.
