In my research I address the most classical evolutionary question, the origin of species. I am a marine biologist and primarily use marine molluscs as model organisms. In the field of ecological speciation, I study the processes and mechanisms by which populations diverge as a result of mechanical isolation, resource competition or use of alternative environments. I explore how divergent populations successfully evolve reproductive isolation and the genetic mechanisms to link selection to reproductive isolation. At present, my research focuses on the evolution of genital divergence and how genital form is linked with reproductive character displacement and reinforcement.
I also have a genuine interest in phenotypic plasticity. Phenotypic plasticity is an important developmental strategy among many prey organisms against predators. Several marine and freshwater snails have become key model organisms for studying traits that have evolved in association with various predators, as well as about costs of phenotypic plasticity.
My final research direction focus on how scientific results are published, selective reporting and how large social events may distort science. We mainly use statistical methods such as meta-analysis and meta-regression in order to test for scientific objectivity and rigour.
