My research interests are systematics, life histories, morphology, ecology and natural products from Caribbean marine algae.
Present research involves study of secondary metabolites of algae which display biological activity.
Role that these compounds play in the physiology of the organisms that produce them and the environmental control of their synthesis are topics currently under investigation. Along with Dr. Nilda Aponte, we have recently completed A Revised Checklist of the Marine Algal Flora of Puerto Rico . Opercular algal growth on the cichlid fish, Tilapia aurea , cultured in seawater. Ballantine, D., and H. J. Humm. Benthic algae of the Anclote Estuary I. Epiphytes of seagrass leaves.
