I am a conservation scientist interested in the integration of quantitative, interdisciplinary and transdisciplinary approaches to face conservation challenges. With particular interest in nature conservation, human-wildlife interactions, and large carnivores and other megafauna in human-dominated landscapes. These species are among the most controversial and challenging group of species to conserve and coexist with, in our crowded planet. Keeping a strong emphasis on the applied nature of my research, I aim to inform, and interact with, managers, policy-makers, interested stakeholders, and the general public, for an effective conservation of nature. I actively seek for a dialogue among disciplines, considering the ecological, psychological, political, legal and socio-economic processes connected to conservation. My current research lines include: i) the study of the phenomenon of coexistence between large carnivores (e.g., wolves and bears), and other megafauna (e.g., elephants, vultures), and human activities (e.g., farming, infrastructure development, ecotourism), as well as the mitigation of negative interactions between these species and humans, and associated social conflicts; ii) wildlife trade (e.g., CITES) and the fight against poaching and illegal wildlife trade; iii) the environmental rule of law (i.e., from implementation to enforcement and compliance of laws); iv) or the search for new approaches for an effective conservation of nature. My collaborative approach has resulted in multiple internationally collaborations, being co-authored by >800 researchers from >45 countries. I am involved in translating science into policy and decision-making, both at national and international levels (advisory activities, contracts, IUCN, dialogue law-ecology). I have participated/collaborated in 40 R&D projects and 100 research contracts (>50 as PI/co-PI), with a high degree of internationalization and funded from multiple sources (regional, national, EU, international institutions and foundations). I give a particular attention to communicating research, interacting frequently with the media, different stakeholders and the general public. I have published >190 peer-reviewed publications, including pieces in multidisciplinary and conservation-related journals, such as Science (15), Nature Ecology & Evolution (4), PLOS ONE (14), Scientific Reports (13), Bioscience (6), Biological Conservation (29), Conservation Biology (5), Conservation Letters (4), Conservation Science and Practice (5). Complete list of peer-reviewed articles can be found here. I have contributed with >120 presentations in national/international congress, 30 books and/or book-chapters, >50 talks by invitation, and >105 scientific/technical reports to decision-makers. Productivity indicators: h-index: 55 / i10 index: 130 / citations: 12220 / m-quotient: 3.2 / G-index: 107. I have participated in 23 workshops related to conservation and management issues at national (e.g., large carnivore conservation) and international levels (e.g., CITES). Among the best 10 conservation scientists ranked worldwide (among the best 5 in Europe, and 1st in Spain) with expertise in wolves according to Expertscape, in 2021 and 2022 (link). Among the top 100 Ecology and Evolution scientists in Spain according to Research.com. I have been involved in the supervision of 6 post-doctoral researchers, 19 PhD students, 17 MSc students and 21 Licentiate dissertations, in national and international institutions. I have been involved in advisory activities for public (regional and national authorities) and private (companies, NGOs) in the conservation of large carnivores, and nature conservation. Extensive experience analysing the degree of implementation and compliance with different environmental laws and regulations (scientific member of Claws and Laws: An interdisciplinary research initiative about law and biodiversity conservation. My work has been used by several decision-makers.
