I am an evolutionary ecologist with background in both ecology and molecular biology, and a taste for statistics. I am fascinated by adaptive evolution, and take a particular joy in developing empirical studies grounded in theory.

My current motivation stems from the conviction that combining evolutionary ecology and parasitology will be crucial when addressing contemporary issues, such as mitigating the impact of human activities on ecosystems. Read more (for example) here.

I am part of the Theoretical Ecology Group, and have recently also joined the Department of Natural History 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 in France I developed from scratch a course in general ecology including field and lab courses. I also taught in behavioural ecology, parasitology and human evolutionary biology.

During my time in Bergen I have been responsible for teaching various topics in ecology, evolutionary biology, and parasitology.

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

In 2017 I set up a longitudinal study of hole-nesting birds near Bergen that will be used as a resource for teaching behavioural ecology (collaboration with Sigrunn Eliassen).

Currently I am working part-time as a researcher at the Centre of Excellence in Biology Education (bioCEED), focusing on the benefits of practice-based learning.

Publications in national current research information system (CRIStin)

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 monitor parasite populations to investigate how selection on parasite traits varies with environmental change, how parasites respond to selection, and what trade-offs are underlying evolutionary changes in parasites. We use the salmon louse as a model for anthropogenic parasite evolution. Please get in touch if interested.

Behavioural ecology of host-parasite interactions

How do parasites affect host behaviour? I have studied this in wild passerine birds.

In southern France and Corsica (CEFE, Montpellier) female blue tits Cyanistes caeruleusgarnish their nests with aromatic plants. Via field experiments I have shown that by doing so they reduce bacterial loads on their offspring, especially those most infested with ectoparasites, which in turn makes them grow faster. This behaviour thus appears as a special kind of maternal care taking the form of preventive medication.

In populations of great tits Parus major studied by researchers from the EGIin Oxford I have studied how avian malaria affects the social behaviour of hosts, and how bacteria are spread on social networks.

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.
