Research interests:

Current project:

Humans offer an exciting new study system for me to apply an evolutionary perspective to questions that have traditionally not been regarded in an evolutionary frame work. I hope to contribute to the growing understanding of humans as a species among other species by exploring the possibilities and limitations of an evolutionary approach to human behaviour in general and the interplay between the sexes in particular.

Thus, in my current project, I aim to understand past and present evolutionary patterns and sex differences in humans. The idea that a trait can be beneficial in one sex but detrimental in the other, resulting in a sexual conflict and hence different selection pressures in the two sexes, has received tremendous attention in the field of evolutionary biology. However, despite widespread general interest in sex differences in humans within the social sciences and evolutionary psychology fields, the genetic basis of sexual conflict remains unaddressed in humans. I use an extensive dataset to, first, investigate if sexual conflict on the genetic level has been present historically in a human population, and second, to investigate how the patterns of sexual conflict have changed over time as the population has gone through extensive environmental and social changes over the past 200 years.

PhD and first postdoc:

The focus of my work was on sexual selection within a behavioural and evolutionary framework. I have used large-scale breeding experiments in a laboratory population of zebra finches to address fundamental questions that remain unanswered despite decades of research on this model organism in studies of sexual selection in monogamous species. My studies of sexual selection in zebra finches lead to a re-interpretation of the function of several key traits in this model organism. The focus of my PhD was to perform a rigorous investigation of how male zebra finches achieve reproductive success. To do this, I evaluated the signalling value of candidate traits and investigated the mechanisms that lead to reproductive success through both intra- and intersexual selection. This work included the use of a quantitative genetic approach to look at selection pressures under semi-natural aviary conditions. Further, I tested both the early condition dependence and amount of inbreeding depression of a broad range of traits so that I could compare both the environmental and the genetic condition dependence of sexual and nonsexual traits and between traits in males and females. I found that zebra finches are remarkably resilient to developmental stress and that inbreeding is an effective means to study the genetic condition dependence of sexual traits. Lastly, female reproductive investment can be influenced by male quality. In contrast to previous studies, I found that females invested more when paired to a less attractive male.
                                                                                                        
My post-doc position continued this work and delved deeper into elucidating the function of song in zebra finches. I found that singing activity does not increase paternity success but rather functions in reproductive stimulation of the partner. To study song complexity rather than singing activity, I used a quantitative genetic approach to study the potential for song complexity to honestly signal genetic or environmental quality, to attract females and to result in increased paternity.

The Media:

I am committed to the public awareness of science. I have written media releases for each of my published articles. Several of my articles have, after additional telephone and radio interviews, appeared in the popular media (e.g. in the American ‘Discover magazine’ and ‘Science news’, in the British ‘Metro UK online edition’, in the Swedish leading newspapers ‘Svenska Dagbladet’ and ‘Dagens nyheter’, in the German newspaper ‘Die Welt’ and scientific magazine ‘scinexx’, as well as on web pages such as ‘Science Daily’ and the German ‘Wissenschaft.de’).
