PhD. (1987) in Marine Ecology by the University of Oviedo, Spain. Lecturer of Ecology in the same university. Expertise and interest lie in the field of the experimental marine ecology: population biology of expanding macroalgal species, the factors influencing the structure of macroalgal dominated communities and the plant-animal interactions in the marine benthos. Five representative papers:
