Research interests

In Seismology special attention has been paid to problems concerning radiative transfer theory, scattering phenomena applied to seismic coda waves and seismic engineering. With respect to Geomagnetism, the research has focused on the Ionosphere, with a particular emphasis on electron density anomalies and theireffect on electromagnetic signals transmission. In the last years a special stress has been put on the study of the Martian ionosphere and magnetic field, and the impact of Solar-Terrestrial phenomena on the Earth´s ionosphere. Since 2010 until 2015 was Member of the MARS METNET SCIENCE TEAM.

This scientific activity has been complemented by a continuous attention to the International Cooperation. Some of the activities in this field are:
Scientific Missions: Spanish Geophysical Mission in Manizales (Colombia) to collaborate in the Nevado del Ruiz Volcano emergency (November-December, 1985).
Technical Assistance to Central America on Natural Hazards (1999)    
Academic Activities: Seminars on Seismology in Colombia (Universidad del Valle, Cali, 1995,1996), Perú (Universidad Nacional de San Agustín, Arequipa, 1995) and El Salvador (Universidad Nacional de El Salvador, 2002).
