My research focus on major questions within the field of Conservation Biology: (1) the factors that influence population establishment and extinction, from natural processes to conservation reintroductions, (2) population expansion, including the movement and range prediction of invasive species, (3) the impact of climate change on populations and ecosystems, and (4) how to transition to a sustainable food production system based on insect protein. My work include large-scale introductions, small-scale experiments, genetic analyses, predictive modelling and theory development. Its stakeholder focus has been broad and ranged from academic development, to local community work, government policy and industry standards. I am also a member of SLU:s Future Lab where we in trans-disciplinary collaborations focus on sustainable Futures.
I am the head organiser and teach on the course:
Naturvårdsbiologi - Conservation Biology BI 1244
I teach on the courses:
Tillämpad naturvårdsbiologi - Applied conservation biology BI1318

I supervise master projects within ecology in a wide spectrum of areas and in different taxa
Recent theses are:
Caroliné Olofsson "Changed behavior in the house cricket Acheta domesticus: predetermined or an effect of learning?"
John-Christophe Hessler Frelinckx "Behavioural study of the house cricket (Acheta domesticus): individual boldness and personality"
Douglas Hunter "Feeding the 45 million: substituting soybean meal with insect meal within EU poultry & egg production"
Johanna Rosenquist "The effect of environmental l and disturbance factors on the presence of different crab species in Pranburi Forets Park, Thailand".
I am keenly aware of the value of interdisciplinary collaborations to enhance the scope and research quality. I am also active in sharing my research and experiences with students continuously in my teaching and supervising, and by participating in projects and developmental activities run by governments, communities & industry.
