Physiology and genetic regulation of toxicity in dinoflagellates, their bloom dynamics and ecology, and the global biogeography of toxic Alexandrium species. Ongoing research programs involve the development of new techniques to identify and quantify these toxic cells and their toxins using molecular "probes", the search for the genes involved in toxin production, development of species-specific indicators of nutrient limitation and cell physiology, and the development of methods to directly control blooms. Anderson also heads a team of 14 investigators from 9 institutions who are conducting a 5-year field investigation of the ecology and oceanography of toxic Alexandrium blooms in the Gulf of Maine between the Canadian border and Massachusetts. He serves as the Director of the U.S. National Office for Marine Biotoxins and Harmful Algae, located at the Woods Hole Oceanographic Institution (http://www.redtide.whoi.edu/hab/).
