Research Interests

Ecology, evolution, herps and genomics are some of the topics that interest me most.

My research interest lies in understanding ecological gradients through altitude. I am approaching to this goal from several perspectives: studying the stable isotope ecology (trophic ecology), performing a parasitological study from an evolutionary point of view, and studying population genetics. For my PhD thesis I use a small mammal community as a model.

I have been studying amphibians and reptiles in the Iberian Peninsula and in Morocco. I have been working on altitudinal gradients with lizards (large Psammodromus) in Sierra Nevada (South of Spain), by means of skeletochronology (histological technique that permits to infer the age of the individual studied), and with the Atlas day gecko in the High Atlas (Morocco), using stable isotopes analysis. I also studied the Pyrenean newt using a parasitological approach (in the Pyrenees, North of Spain) and salamanders in a Mediterranean mountain range (Beni Snassen, Morocco).
