I collaborated on a project on the taxonomy of microarthropods in Spain, but I soon focused my research interests on the ecology of birds participating in a project on the breeding and feeding ecology of a bird species in southern Spain. During my PhD research, I studied the breeding ecology of a bird assemblage in an arid area of western Argentina under the supervision of Dr. Luis Marone. This study included basic aspects of the breeding ecology of this poorly known avifauna. This mostly descriptive work was a necessary first step for testing hypotheses and planning realistic as well as biologically meaning experiments. I also evaluated the role of nest predation as a potential selective pressure for life history trait evolution and the selection of nest sites. During my stay in Argentina, I had the opportunity to collaborate on a project that Dr. Tom Martin conducted on the reproductive ecology of birds in a temperate area of South America. In Spain, I participated with some colleagues in the study of bird communities in forests and reedbeds of central Spain. Topics of this research included: movements and migration, biometry, habitat use, and community ecology.

Recently, my research interests have focused on animal-plant interactions. As a post-doctoral fellow at New Mexico State University and the University of Wyoming I conducted a project evaluating reciprocal selection and coevolution between Common (Red) Crossbill (Loxia  curvirostra) and Aleppo pine (Pinus halepensis) in the Mediterranean.  I have more recently completed a project on crossbills and mountain pine (Pinus uncinata) in the Pyrenees and in isolated ranges to the south to further address the importance of and conditions favoring coevolution between crossbills and Mediterranean pines. I continue working on this and other systems in Spain. I teach at the Polytechnic University of Madrid.
