I am a full Associate Professor at the Department of Ecology of the Autonóma University of Madrid (UAM), where I am  working since 2000. My scientific interests in Ecology are focused on the study of basic concepts such as the ecological niche and its implications for the coexistence of species. I study the niche through the analysis of habitat selection and hoe species share/segregate resources at multiple scales. I usually use vertebrate species as models for my research, with emphasis on the study of steppe birds (in Spain and North Africa), domestic and wild ungulates, especially guanaco (in South America) and micromammals. I am also interested in other interspecific relationships, especially predation. The relationship between basic research and its application is made through the biology of conservation. Currently I supervise several research projects focused on the conservation of the Dupont’s lark Chersophilus duponti. All of this without forgetting my early beginnings dedicated to the study of the structure and dynamics of  Mediterranean grassland communities.

I am involved in the teaching of the Degree in Biology at the UAM, and of the Official Master in Ecology UAM-UCM, where I teach both theory and practice in four different subjects.
