I am a Marie Curie IO Research Fellow in the Department of Zoology at the University of Cambridge, UK.
As an evolutionary biologist (with emphasis on genetics) I am interested in the complexity of natural systems. I primarily study natural populations of arthropods, particularly butterflies. Broadly, I have two main research areas (see RESEARCH for more info):
1) The causes and consequences of spatial and temporal variation in arthropod host-symbiont interactions.
2. Investigating the genetics underlying adaptive variation in natural populations, using genomics approaches.
Although it is becoming increasingly feasible to obtain informative genomic data for any species, analysing genetic variation in non-model species is still challenging. I have therefore become interested in assessing the utility of high-throughput sequencing techniques in non-model species, and using such tools to answer questions of natural systems.
While I started my academic life as predominantly a field biologist (and this still is a very important part of my work), in order to investigate natural processes I now combine disciplines such as evolutionary biology, population genetics, genomics, bioinformatics, molecular biology, physiology and ecology.

I am now located at Cambridge University, UK. It's lovely to be back, especially in the springtime.
