I am an animal ecologist interested in human-wildlife coexistence. I study both the influence of people on wild animals, and the influence that wild animals have on people. I have a soft spot for small carnivores, work mostly with mammals, but am generally interested in all wildlife. Furthermore, I have a strange interest in parasites and diseases, urban ecology, citizen science and social aspects related to wildlife.
My main tool to study animals are camera traps, although I don't shy away from other sources of information such as GPS collars and genetic data. I am involved in further development of camera trap deployment and data analysis.
I gave a TED talk at TEDx Ede in 2016, which can be viewed here:
I co-manage the Megafauna & Sustainability research unit together with it's leader Dr. Joris Cromsigt.
I am coordinator of the research school Ecology & Society (ECOS) run by the department of wildlife, fish, and environmental studies and the department of forest economics at SLU. We offer courses, workshops and seminars in topics on the interface between ecology, economy and sociology. I am coordinator for one of the courses: Ecology for non-ecologists, in which we teach the basics of ecology to PhD students that work in multidisciplinary projects including ecology but with a background in other sciences.
I am also the coordinator for PhD education at the department
I give some lectures in the Fish and Wildlife Census Techniques (BI1302) and Applied Population Ecology (BI1301) courses.
I work in several projects, which are presented in random order.
Scandcam is a collaboration between SLU and NINA in Norway that studies mammal communities using camera traps. Our main goal is to utilize data from a camera trapping grid that was deployed to study Lynx family groups to study interactions between species within the whole mammal community.
Beyond Moose studies the interactions between different ungulate species in multi-species communities. I am mainly involved in using camera traps to study these interactions.
ARCS - Arenas for co-operation through citizen science is a collaboration between Göteborg University, Umeå University, SLU and Vetenskap och Almanhet (Science and Public). We are building a platform supporting citizen science in Sweden. I am coordinating the workpackage on standardization and quality of data in citizen science.
Meet your wild neighbours / Träffa dina vilda grannar is a pilot project funded through SLU Urban Futures where we use citizen science and camera traps to study wildlife over an urban to wild gradient. Within this project, I collaborate with dr Roland Kays at the North Carolina Museum for Natural Sciences and North Carolina State University, Umeå kommun, Naturskolan and Svenska Jägareförbundet Västerbotten.
I work together with researchers at the Norwegian Institute for Nature Research (NINA), North Carolina State University, Göteborg University, Umeå University and different departments at SLU. Next to that, I work together with (local) stakeholders such as Umeå kommun, Vetenskap och Allmänhet and Svenska Jägareförbundet Västerbotten.
2012-2016 PhD in Disease ecology at Wageningen University, the Netherlands
2009 - 2011 MSc (with distinction) in Ecology at Wageningen University, the Netherlands
Currently I (co-)supervise one PhD student Nannet Fabri and several MSc students.
If you are interested in doing an MSc thesis topic with me, please feel free to contact me.
