People

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.

I am a university lecturer in environmental biology. I am motivated by applied ecology questions, and by finding approaches that help people make more sustainable decisions. Much of my recent research examines how multiple uses of forests and biodiversity can be better reconciled.

In the  project we provide knowledge to help Finnish forest sector become more just and sustainable.  

In the project “” (Metsästä buustia hyvinvointiin ja terveyteen) we link forest characteristics to human health and well-being, and eventually assess the economic costs/savings from forests around human settlements.

I have also worked in tropical systems, wetland birds, human-wildlife interactions and pastoral systems

I teach mainly within the .

Tiago Monteiro-Henriques completed his PhD in native vegetation at the Universidade de Lisboa, Portugal, in 2010. He is a postdoctoral researcher since 2017 (FCT grant ref: SFRH/BPD/115057/2016; 2017-2023), based at the Universidade de Trás-os-Montes e Alto Douro, but in association with GCC Lab, where he conducts short-term stages. He has a background in native vegetation and landscape research with particular interest in numerical analysis and classification of vegetation data, flora and vegetation mapping, ecological modelling, nature conservation, and ecological restoration.

His current research activities focus on native forests from the Iberian Peninsula and aim to create i) a general systematization of forest types using combinatorics and optimization; ii) spatially explicit models of their potential and actual distributions; iii) an endangerment assessment of those forest types, linked with fire patterns and global changes and iv) disseminate all of the produced information on the web along with specific tools to support management and conservation actions and respective prioritization.

Pablo Manzano completed a PhD in Ecology and the Environment in 2015 at the Universidad Autónoma de Madrid, researching seed dispersal ecology in Spanish sheep-grazed rangelands. Since finishing his MSc in 2004, he has been working first on his PhD field work and then in a series of international development initiatives that took him from the Western Balkans to two global positions in IUCN in Nairobi and in FAO in Rome, both related to pastoralism. In these years he has kept his research agenda on rangeland ecology but expanded into other disciplines of the pastoralist domain, including economics, sociology and anthropology. His research approach aims to integrate the social, economic and environmental livelihood dimensions. He is currently a HELSUS fellow addressing global pastoralism sustainability.

Federica Manca is interested in how species interact in coastal marine ecosystems, and in how biotic interactions modulate the response of marine ecosystems to climate change. She completed her MSc in Marine Biology in Italy in 2016 with a thesis on coral-associated fauna in the Maldives, and in the following years worked on different research projects in Japan and Italy. Her PhD research focuses on marine vegetated ecosystems in the Baltic Sea, where she uses ecological network analysis to explore the web of interactions between marine macrophytes (macroalgae and seagrasses) and their associated fauna, and to model how macrophyte-dominated communities will shift under future scenarios of climate change. She is also a member of the at Tvärminne Zoological Station.

I am conducting my PhD at the ELOISA doctoral programme. I am passionate about conservation biology and herpetofauna and did my master’s thesis on amphibian and reptile diversity across agricultural landscapes in Guinea-Bissau, West Africa. For my PhD, I am building on the same topic, investigating how different types of oil palm plantations—traditional and industrial—affect herpetofauna communities in Liberia, and how these compare to old-growth forest. Furthermore, I will explore the snake-human conflict in these plantations, looking at how snakes are perceived and how that affects snake communities, and whether oil palm plantations increase the risk of snake-bite envenoming, a high-priority tropical disease, as classified by the WHO.

My name is Mihika Sen, and I am a Doctoral Researcher in the Interdisciplinary Environmental Sciences Doctoral Programme at the University of Helsinki. My research primarily focuses on mitigating negative human-elephant interactions across Asia and Africa. I completed my Master's degree in Ecology and Evolutionary Biology at the University of Helsinki, conducting my Master's thesis on the social and ecological effectiveness of electric fencing as a mitigation tool against crop-raiding elephants in Laikipia county, Kenya. For my PhD, I will be studying individual-level variations in the crop raiding behaviour of Asian elephants in Assam, Northeast India. I will also investigate shared local knowledge and perceptions of farmers in Assam towards elephant behaviour. The overall aim of the project is to develop an adaptable and sustainable individual-level crop raiding mitigation framework, balancing the needs of both elephants and local communities.

I am a PhD researcher in the Doctoral Studies in Ecology, Evolution and Environmental Sustainability in Society (ELOISA) and work for the Finnish , which funds my PhD. I am also part of the Global Change and Conservation Lab (GCC) at the University of Helsinki. 

In my research, I am looking at the breeding and movement ecology, as well as various conservation challenges, related to the Finnish wild forest reindeer (Rangifer tarandus fennicus). More specifically, I am looking at their post-calving habitat use in the two Finnish populations at different spatial scales. Additionally, I will investigate the influence of predation on their habitat use and small-scale movement. Ultimately, I will also try to assess the risks and feasibility of a potential reintroduction of this near-threatened subspecies to a new area in eastern Finland, with the help of local and traditional knowledge. 

I have worked with these animals already in the past, during my Master’s in Ecology and Evolutionary Biology (EEB) at the University of Helsinki. Boreal and arctic ecosystems, as well as their species, are of special interest to me. Especially large, cold-adapted mammals fascinate me. Another interest of mine is applied conservation, and recently, I have also been learning about the value of local and traditional knowledge in science and conservation.

I am a conservation biologist and PhD candidate in the Doctoral Programme in Ecology, Evolution and Environmental Sustainability in Society (ELOISA). I hold a BSc and MSc in Conservation Biology from Ghana and France, respectively.  

My PhD examines whether African elephants act as climate allies by shaping carbon stock dynamics in tropical ecosystems. In collaboration with African Parks, I combine dietary metabarcoding of forest and savanna elephants across four African countries with camera trapping, non-invasive DNA sampling, dung count surveys, vegetation surveys, plant trait analysis, and remote sensing, along with two decades of human elephant conflict records from Ghana. These approaches allow me to assess whether elephant foraging promotes carbon dense tree species and to identify where climate mitigation and conflict reduction can align.

I am doing my PhD in the ELOISA doctoral programme. I endeavor to create comprehensive, multidisciplinary understanding and solutions for conservation challenges like human-wildlife conflicts. Studying very broadly, I have delved into the ecological, geographical and human dimensions of conservation. I am also passionate about science communication and inspiring the next generation, reflected in my teacher studies and work experience. 

In my PhD, I look to advance our understanding on the conflicts and coexistence between humans and large carnivores. Focussing on the brown bear, I strive to understand how the fear of humans affects the behaviour of carnivores and what implications this has for coexistence. Moreover, I am evaluating what methods are currently used and developing new solutions to facilitate human-carnivore coexistence in a time when increasing populations of large carnivores pose new challenges for carnivore conservation.

I am a doctoral student in the ELOISA doctoral programme and passionate about mammal behaviour and acoustic communication. Conducting my master thesis research in Bethlehem, South Africa, I was able to show that female lion roars contain information about the individual calling. Building on this foundation, my PhD research continues in the field of bioacoustics, where I am investigating acoustic signalling in mammalian species with a focus on the Eurasian lynx (Lynx lynx). Going from an individual level to community dynamics, I will look at what vocalisations lynx use in the wild, exploring individual, sex and age differences as well as geographic variation. Additionally, I will focus on investigating how effectively lynx use their habitat for sound propagation, how human modification affects their calling behaviour, and how other species respond to their calls. My PhD research is conducted in close collaboration between the GCC lab and the led by Dr. John Loehr.

I am a doctoral researcher at the GCC Lab and the ELOISA doctoral programme at the University of Helsinki (UH). My research primarily focuses on human-carnivore interactions and biocultural conservation. I completed my BSc in Biology at the University of Barcelona (UB) and MSc in Ecology and Evolutionary Biology at the University of Helsinki (UH), with experience in ecology, conservation genetics and social-ecological systems in Spain, Madagascar, Finland and Kenya. 

With my PhD, I aim at understanding changes in the use of carnivore skins in a cultural ceremony from the Daasanach community in East Africa. To do so, I am using an interdisciplinary approach, combining genetics with social science methodologies.

I am a doctoral researcher in the Environmental Science and Technology Doctoral Program at ICTA-UAB (Universitat Autònoma de Barcelona), conducting my project within IEK-CHANGES () led by Àlvaro Fernandez-Llamazares, GCC alumni and long-term collaborator of the GCC lab. My hesis is also co-supervised by Mar Cabeza. My research explores the links between changes in Indigenous Environmental Knowledge (IEK) and biodiversity loss. I work in close collaboration with the Tsimane’, an Indigenous people from the Bolivian Amazon, and I use participatory and arts-based methods—such as music, photovoice, and futures thinking—to better understand their perceptions and interpretations of IEK and environmental changes over time.

Previously, I studied non-human primate behaviour and conservation, which highlighted for me the importance of integrating Indigenous knowledge and interdisciplinary approaches into biodiversity conservation. Only through such integration can we achieve meaningful biocultural conservation and restore ecosystems sustainably.

I am a Doctoral Researcher in the ELOISA Doctoral Programme. I completed my master’s degree in Geography at the University of Helsinki, with my thesis focusing on impact of biotic interactions on the distribution of arctic and alpine plants in Fennoscandia. In addition to geography, I have especially studied biology and geoinformatics. Since graduating, I have worked in areas such as climate change mitigation, hazardous wrecks, and geoinformatics. In my doctoral research, I combine this diverse background with a focus on marine environments. My research aims to develop GIS tools and methodologies for integrating marine social-ecological models in a digital twin framework. I will also examine how GIS-based tools can improve decision-making in marine conservation and management. I also work as a Research Scientist at the Finnish Geospatial Research Institute (FGI).
