I did my PhD at Lund University in Sweden studying the migration ecology of Red Admirals (Vanessa atalanta). During this time I organised and participated in an exchange course travelling to Nigeria and realised that African butterflies were more than just interesting, they were addictive! While finishing up the PhD I started going to Nigeria on regular research visits, doing both pilot studies for potential future projects and helping various NGO:s with bio-monitoring in the rainforest areas of Cross River in South Eastern Nigeria and the western Niger Delta. At a seminar back in Sweden I met Paul Brakefield and to sum it up shortly I left Sweden and worked as a post-doc in Pauls lab for the next two years funded by the Swedish Wenner-Gren Foundation. When Paul moved to Cambridge the initial Post-doc was extended for another four and a half years at Cambridge starting in January 2011 funded by the European Research Council.

When absent from the office I can usually be found in the tropics hunting for butterflies, or under classic cars swearing at rusty old bolts and failed MOT:s.

Research Group

Radiating Butterflies:
Postdoctoral Research Associate

Research Interests

My main research focus is the evolution of sex-pheromones and genital structures, and their role in speciation processes. Beside that I am also interested in the early shifts in food-plant among Bicyclus butterflies. Even though my main focus have long been the Bicyclus, I have recently started to investigate a lot of taxonomic issues of the Asian part of the Mycalesina radiation and currently working on several re-curation projects in major museum collections.
