Main Research Interests

My main research interests involve studying the genetic basis of adaptation to the laboratory by monitoring the dynamics at the genomic level in replicated populations of Drosophila subobscura since foundation from the wild. In that sense, I am characterizing microsatellites and inversions polymorphism as well as gene expression changes through time from a former to a later generation in the lab. At the same time, I intend to relate the evolution at the genomic level with the dynamics of phenotypic traits more or less closely related to fitness. With this study, our group aims to understand the response at the genetic level of populations adapting to a new environment and mostly clarify the role played by selection vs. genetic drift in the process of adaptation.
