I'm mainly interested in bats' evolution and ecology. Throughout my career, I have enjoyed participating and leading field expeditions from temparate to tropical regions worldwide. My contributions focus on the understanding of the ecology and evolution, mainly of bats, and particularly the reconstruction of phylogenetic relationships and the identification of cryptic species through the use of morphological and DNA markers. I've also collaborated continuously with the ISCIII in the study of bats' viruses and their coevolution processses in the last 15 years or so. In parallel, I've always kept interest in the conservation of biodiversity not only of bats and its conflict with human activities. This has resulted in my collaboration with the UN system (FAO; UNDP, UNESCO, etc.) for years and my participation in IUCN working groups and in other international organizations such as Eurobats (UNEP) and Bat-Life and the Spanish Bat Society.
