I am an evolutionary ecologist with broad interests in ecology and evolution, in the context of a rapidly changing world. Most of my research combines multiple approaches and perspectives.

My main current focus is on the global change of species interactions, and more specifically on anthropogenic evolution of infectious organisms. Understanding how we humans cause selection on parasites and pathogens is of crucial importance, not only in terms of human and animal health, but also because of the links between disease and biodiversity

Here at UiB I collaborate most with the Theoretical Ecology Group, the Evolutionary Ecology Group, the Fish Disease Group, and the University gardens where I monitor hole-nesting birds. On the teaching side I have collaborated with the interdisciplinary Center for Womens and Gender Research, the Centre for Excellence in Biology Education, and the Department of Natural History, where I have been in charge of permanent exhibitions on Evolution at the University Museum.

Course development and teaching

I started teaching in 2004 as a teaching assistant, and have since held various positions and taught at various levels (from bachelor to doctoral courses), and on a broad range of topics (from plant biology to behavioural ecology). 

As an associate professor I developed from scratch and coordinated a practice-oriented course in general ecology. I also taught in behavioural ecology, parasitology and human evolutionary biology.

During my time in Bergen I have supervised 2 PhD students and 4 MSc students. I have also taught in ecology, evolutionary biology, and parasitology courses.

I taught about natural & sexual selection, adaptive evolution, and Darwin's biography to Humanities students at the Centre for Women and Gender Studies.

Since 2017 I am monitoring a nestbox bird population that is also used as a field site for students of the behavioural ecology course.    

I am also collaborating on the PRIME project within the Centre of Excellence in Biology Education (bioCEED), researching on the benefits of practice-based learning.

I have been using a wide range of organisms depending on the research question (bacteria, parasitoid wasps, Drosophila flies, parasitic blow flies, salmon lice, birds). Here is some more information on my two favourite study species. 

The salmon louse Lepeophtheirus salmonis

What exactly are salmon lice? What is their biology and what do they do to their hosts? What do we know about them?

The Salmon Lice Research Centre (SLRC, Bergen) has prepared a little overview here: The Atlantic salmon louse, Lepeophtheirus salmonis

The blue tit Cyanistes caeruleus 

Blue tits are my favourite study species; I have been watching their behaviour for about 30 years (yes, that long!) and they have been involved in my research since 2003. I have studied their olfactory abilities, their behavioural responses to parasitism, and more recently their extra-pair mating behaviour.

Blue tits are widely used as a model species in evolutionary ecology because they can be ringed and their reproduction can be monitored using nestboxes, which they readily adopt. This allows to collect large amounts of longitudinal data that can be used in many ways, and in particular to study processes of adaptive evolution in the wild.

The blue tit is a non migratory bird species, which means it can be seen throughout the year in Europe. It is a territorial, socially monogamous species where different pairs breed on different, adjacent territories. Copulations (including extra-pair copulations) occur in early spring. Females build a nest in a cavity (or a nestbox) and lay clutches of 6-12 eggs, which hatch after ca. 2 weeks and the chicks fledge ca. 3 weeks later. The young rely on food and protection provided by both parents.

Ecology & Evolution of parasites

In the ParAnthropE project (NFR, FRIMEDBIO, 2019-2023) we investigate how selection on parasites varies with environmental change, how parasites respond to selection, and what trade-offs are underlying evolutionary changes. We use the salmon louse as a model for anthropogenic parasite evolution. Please get in touch if interested.

Behavioural ecology of host-parasite interactions

Do free-living animals medicate themselves and how? This was the topic of my PhD.

In southern France and Corsica (CEFE, Montpellier) female blue tits Cyanistes caeruleus garnish their nests with aromatic plants. In a series of field experiments over 4 years, I have shown that by doing so they reduce bacterial loads on their offspring, who then grow and develop better. This behaviour thus appears as a special kind of maternal care taking the form of preventive medication. It was featured in a documentary movie by Jacques Mitsch: "Les animaux médecins" (2014) and on BBC Earth News

I also study this behaviour in our local nestbox population in Bergen - get in touch if interested! 

Effects of predation risk on behaviour and extra-pair mating

Recent theory suggests that extra-pair mating might create incentives for males to invest more into behaviours that are beneficial for their neighbourhood, because their potential reproductive success is spread out among several nearby nests (click here for a Nature News & Views on the topic). Using longitudinal data combined with field experiments in the blue tit Cyanistes caeruleus, I have been investigating the links between predation risk, extra-pair mating and parental behaviour.
