After taking a degree in Biology at the University of Santiago de Compostela (1973), he took his doctor’s degree four years later. Nowadays, he is a Professorof Ecology in the Faculty of Biology and director of the Cellular Biology and Ecology Department (University of Santiago de Compostela). He is a Professor in the Faculty of Biology and teaches Environmental Engineering at the Polytechnical School.
He wrote the following books and monographs: Bioclimatología de Galicia (1983), Barrié de la Maza Foundation, A Coruña, La alelopatía y su papel en las comunidades vegetales. Revisión crítica, metodológica y bibliográfica (1992). ‘Serie Cadernos de Revisión’ – Santiago de Compostela University, Estado de conservación del litoral de Galicia. Metales pesados y nutrientes en sedimentos y organismos de la franja intermareal, 1997, Conselleria de Pesca-Santiago University, Atmospheric heavy metal deposition in Europe 95-96, Nordic Council of Ministers, Bancos de Especimenes Ambientales. Una propuesta para Galicia, CITA, Conselleria Medio Ambiente, Xunta de Galicia – Santiago University (2000).
His research activity focuses on the following work lines: Allelopathy, Bioclimatology and Ecotoxicology. Af far as these subjects are concerned, he has published over a hundred scientific articles in very important international magazines, such as ‘Release of allelochemical agents from litter, througfall and topsoil in plantations of Eucaliptus globulus Labill in Spain’ (1991) J.Chem. Ecology; ‘Defining phytoclimatic units in Galicia (Spain) by means of multivariate methods’ (1991) J. of Vegetation Sc.; ‘Stress responses and metal exchange kinetics following transplant of the aquatic moss Fontinalis antipyretica Hedw’, (1994) Freshwater Biology; ‘Influence of watershed lithology on heavy metal levels in estuarine sediments and organisms in Galicia (North west Spain)’, 1996 Marine Pollution Bull; ‘D665/D665a versus frecuencies as indicator of bryophytes responses to physicochemical gradients’, (1997) Ecology; ‘Regional-scale monitoring of coastal contamination.

Besides, he directed twelve doctoral theses and fifty minor theses and projects. He was the main researcher of a hundred projects and research agreements, participated in courses and seminars and directed seminars and masters in Natural Resources, Evaluation of Environmetal Impact and Environment Technology.
He is the main researcher of the Ecotoxicology Group at the University of Santiago de Compostela, responsible for the Galician Bank of Environmental Especimens, reviser of national and international publications, evaluator of CICYT Projects (I Plan+D National) and FONCYT (I+D, Argentina) and rapporteur in the Galicia 2010 Project. Besides, he was the secretary of the Faculty of Biology and was on the board of directors of Santiago de Compostela University. He is on the staff meeting and several academic commissions. Nowadays, he directs the Cellular Biology and Ecology Department.
