Field of Interest: Neurobiology and Neuropharmacology, Neurotoxins of Marine Origin, Ion Channels and Neurotransmitter Receptors.

Excitation phenomena of neural and muscle membranes are studied focusing on the electrophysiological parameters of acetylcholine receptors and ionic channels. The action of bioactive compounds isolated from marine organisms on these membrane macromolecules is investigated using procedures ranging from muscle contractility bioassays to recording of ionic currents. Collaborations exist with scientists at the UPR Mayagüez Marine Sciences Department, UPR Río Piedras Chemistry Department and the UCC School of Medicine Pharmacology Department as well as the Institute of Toxicology of the University of Kiel in Germany. Ongoing research projects include studies of the neurotoxic, myotoxic and cardiotoxic actions of compounds purified or extracted from: benthic dinoflagellates, tropical marine sponges, sea anemones and zooanthids.
