I am fascinated by the processes that underlie biological diversification (adaptation, speciation), and their analysis using integrative research approaches. I use as main research system threespine stickleback fish inhabiting lake and stream habitats. My previous work, combining ecological, phenotypic, and population genetic information from multiple lake-stream systems in Canada and Europe, has investigated how divergent natural selection between these contrasting foraging environments drives adaptive diversification and reproductive isolation. My current work focuses on molecular aspects of stickleback diversification.
Making use of high-throughput sequencing technology for genome scans and QTL mapping, the goal is to shed light on the genetic basis of adaptive diversification across habitat transitions. This work will advance our understanding of the mechanisms driving (convergent) evolution and speciation.
