PhD and master’s degree in psychotherapy interventions from the University of Salamanca, Spain. He is a certified clinical psychologist and works as an associate professor at the National Distance Education University (UNED) in Madrid, Spain. He has experience of more than 20 years in research, with an extensive production of scientific articles. Its main area of application has been the evaluation of personal meanings of clinical subjects and the identification of cognitive conflicts. He has made important contributions in the field of clinical psychology when it comes to highlighting the role of different cognitive conflicts in maintaining the subject’s psychological problems and exploring the “internal coherence”, from the subject’s own meanings, of therapeutic non-change, even when the subject wants such a change. Likewise, he has made more than a hundred presentations at national and international conferences and collaborated in several funded research projects. The latest of them on Psychological treatment of depression in women with fibromyalgia and Cognitive therapy for unipolar depression: efficacy of a therapy focused on implicative dilemmas, in which the evaluation protocol of the Repertory Grid Technique (TR) is used. He is the director of the UNED Constructivist Research Group (GICUNED). A multidisciplinary group, which includes clinical psychologists, methodologists, computer engineers, and health workers from the field of medicine and nursing.
