Research
My research concerns bee health, which is a broad subject covering a diverse range of themes, methodologies and research approaches, ranging from molecular and subcellular pathogen-host interactions through organismal, behavioural and social adaptations to bee parasites and pathogens, to landscape-level, biogeographic and climatic level effects on bee health and productivity.
Bee Health & OneHealth:
Zooming out, bee health is a critical component of the OneHealth concept, which emphasizes the interdependency of plant, animal, environmental and human health. Zooming in, bee health is defined by how bees employ different adaptive mechanisms in response to various physical, chemical and biological stressors. My main focus is on biological stressors, primarily the parasites and pathogens of bees.
Bee Disease Ecology:
One major research theme is the distribution and transmission of pathogens within and between bee species; the effect of this on bee health, reproduction and diversity, and the extent to which this can be influenced (positively or negatively) by other environmental factors and human activity.
Bee Disease Adaptive Mechanisms:
Bees can avail themselves of a range of behavioural, organizational, physiological, molecular and genetic-genomic mechanisms to either lower the level (resistance) or the effects (tolerance) of parasites and pathogens. Social immunity is a hugely powerful and flexible additional layer of adaptive mechanisms that is only available to bees that live in large communities, such as honey bees and bumblebees. A lot of our current research involves the triggers and behavioural mechanisms underlying selective removal of diseased bees from a colony, in which viruses paradoxically may fulfill a beneficial role.
Virus Ecology & Evolution:
A niche research interest concerns the adaptative perspective and options for the bee viruses to the challenges posed by their host(s) in various contexts. Of all the participants in bee health and pathology, viruses have by far the greatest adaptive potential, with often radically different adaptive-evolutionary strategies at different levels of organization, all of which is effected in real-time through a relatively small, efficient and easily characterised genome.
Research projects
- FREE-B, a BioDiversa project about free-living honeybees
- POSHBEE, a huge EU-wide project about chemical, biological and other environmental stressors on social and solitary bees stressors

Teaching
I currently teach in two courses: "Bees, Beekeeping and Pollination" (BI1320) which runs every year during May, where I cover the pathogens, parasites and pests of honeybees and their colonies, and "Molecular and Microbial Ecology" (BI1438) which runs between Januray and March, where I cover the bee perspective of animal-microbe interactions, focusing mostly on the beneficial bacterial gut microbiome and intestinal pathogens, as well as occasionally presenting in the "meet the author" section, where I delve more deeply into my own research with the students.
I have previously also taught in "Writing Scientific Papers" (PNG0086), where we dissect the intricacies and hurdles of the publishing world, and also occasionally teach an ad hoc guest lecture in courses at other universities.
I enjoy teaching, especially the interaction and feedback with the students. I always have plenty of scope for students to participate in my research, either as part of their course requirements or as research assistants.
Educational credentials
I received a BSc in Biology in 1983 from the University of Birmingham, followed by a PhD in Genetics in 1987 from the University of Liverpool. I then embarked on a bunch of PostDoc and researching adventures around the world before landing in Sweden in 2005.
At SLU I finally also acquired a series of proper pedagogic qualifications: “Teaching in Higher Education, Basic Course” in 2010, “Kurs i forskarhandledning” in 2011, “Betygskurs Workshop” in 2013 and “How can we use learning outcomes in research education?” in 2018.
