I am a broadly interested in how animals adapt to a world under constant change, such as in relation to a warmer and more unstable climate and as a response to alterations in land use in the broad sense. My research group investigates such questions on several layers of enquiry, ranging classical ecological studies in nature to detailed physiological assessment of e.g. heat production, body temperature regulation and cell biology in laboratory settings. We work particularly with various bird models, ranging small birds in southern Scandinavia to large birds in the High Arctic; all of which inhabit environments facing a variety of contemporary threats.

The work in my lab is in various capacities related to understanding how the environment affects various homeostatic control of various physiological systems; partly in relation to the evolution and function of regulatory mechanisms that help animals keep warm when it is cold and cool when it is warm, and partly on the cellular level where we assess how the engine of the body – the mitochondria – are affected by stressors such as temperature fluctuations and toxins. Within this general framework, we study e.g. if unstable and extreme temperatures in early life, such as when an animal is born during a heat wave or a cold snap, affects how the animal deals with temperature as an adult and whether any such effects accumulate between generations. We are also, increasingly, studying how adult birds are affected by heat waves. Our work show that the risk of overheating suppresses how hard small birds can work to care for their offspring, which carries over to reduced reproductive success.

I studied ecology, animal physiology and statistics at Lund University and the University of Auckland 2002-2007, and defended my PhD thesis at LU in 2012. This was followed by post-doctoral work at LU, the University of Glasgow (2013), the University of Tromsø (2014-2017) and the University of Glasgow (2018-2019). Since 2019 I work as a researcher at LU, and am affiliate staff member of the Institute for Biodiversity, Animal Health and Comparative Medicine at the University of Glasgow.

My teaching is primarily in physiological and evolutionary ecology, human physiology, biodiversity surveying and faunistics. I am head teacher of the departmental course in Field Faunistics. I also manage the departmental questions and answers blog "Ask a Biologist" (in Swedish); an outreach initiative where anyone can ask a panel of expert biologists about anything broadly related to animals, plants, fungi, and nature at large. I am also editorial board member of Oecologia, Journal of Avian Biology and Ornis Svecica.

In parellel with my work in animal physiology, I am an entomologist with expert knowledge of coleoptera, hemiptera and homoptera. As part of this, I undertake insect diversity surveys at different levels. Current projects include a survey of hemiptera and homptera in Gotska Sandön National Park in the Baltic Sea. In my spare time, I am a keen flyfisherman along the southern Swedish coastline and in the mountains in the northern parts of the country.
