Works on active Galaxies and X-ray sky surveys. He founded the first Spanish X-ray astronomy group, still a national and international reference. He triggered new developments in Transition Edge Sensor calorimeters for X-ray astronomy in Spain. He has published over 120 papers in international journals, which have received over 4000 citations (H=35). He's delivered many dozens of conferences by invitation in international meetings, develops significant activities in public outreach and has supervised 7 PhD students – all of them active researchers.
