The Global Change and Conservation lab counts currently with 5 senior/postdoctoral researchers, 6 PhD students, 3 visiting researchers, 4 master students, 4 field assistants and several affiliated researchers with whom we have very close collaboration.

The group pays special attention to equity, striving to be an inclusive, gender-balanced and culturally diverse research team.

Mar Cabeza - group leader

Mar Cabeza is an established PI at the University of Helsinki leading the “Global Change and Conservation” team. After completing her PhD at the University of Helsinki, MC conducted a postdoc at the Biodiversity and Global Change lab in Spain. She then returned to Helsinki to establish her own research team. Most of the research projects that MC currently leads fall under the conservation effectiveness umbrella, by which she attempts to address both ultimate and proximate causes of success and failure of conservation actions. Her current research interests include basic field ecology needed to understand processes at local scales, large scale macroecological studies involving projections of climate change, and the integration of these in conservation assessments and planning. Mar also has passion for education. She is involved in education initiatives at a variety of levels, from school children to advanced PhD students. She is especially interested in capacity building in developing countries. This education passion is also shared by other members of the team.

Aina Brias - PhD Student

Aina Brias-Guinart (MSc in Environment and Development, 2014, Lancaster University) is interested in the social dimensions of conservation interventions. Since 2018, she has been conducting her interdisciplinary PhD research that focuses on the links between education and biodiversity conservation. She is particularly interested in how conservation NGOs implement education programmes in rural communities in Madagascar and how they affect local cultures, environments and knowledge systems. Through this process, she wishes to promote ethical practices in concrete and meaningful ways when doing research, and to bridge the gap between academia and practice. What she loves most about her work is the joy of sharing meals while conducting long periods of research in Madagascar.

Miquel Torrents-Ticó - PhD Student

Miquel Torrents-Ticó completed his MSc in Conservation and Management of Biodiversity at the University of Barcelona in 2012. He was a guest scientist at the Department of Zoology, University of Cambridge. His interest in human-wildlife interactions took him around the world from tropical rain forests to arid deserts, where he worked with different species: Costa Rica (olive Ridley sea turtles), Ecuador (common woolly monkeys), South Africa (meerkats, Damaraland mole-rats), Botswana (large predators) and Namibia (chacma baboons). His interest in conservation has grown along with the ever-increasing conflicts between humans and wildlife. His main interests lay on Human-Carnivore Conflicts. In his PhD, he takes an interdisciplinary approach to understand human-hyena interactions by investigating local attitudes, values and perceptions towards spotted hyenas, and comprehend spotted hyena ecology that links to the human-hyena conflict (e.g., animal movement, density, distribution). Most of the fieldwork is being conducted in Sibiloi National Park and Laikipia (Kenya). He is member of the Hyaena Specialist Group from the IUCN Species Survival Commission and a National Geographic Explorer.
