Research Interests

Speciation genomics has recently received great benefit from advancements in genomic technologies and from the refinement of models describing evolutionary processes generating biological diversity. Currently, a field attracting much attention is the study of “divergence­-with­-gene­-flow” (DWGF), i.e. divergence involving episodes of sympatry or parapatry and opportunities for genetic contact, before reproductive isolation between incipient species is complete.
In my PhD project, I address key questions related to the ecological and evolutionary genomics of DWGF in Populus alba and P. tremula, two widespread Eurasian tree species still able to hybridize despite great genetic and ecological divergence. In particular, the project focuses on (1) investigating the reproductive barriers between the two species, and (2) unraveling the genetic architecture of ecological differences maintained in the face of gene flow. These topics are addressed with the help of Restriction site Associated DNA sequencing (RAD­seq) of common garden grown seedling families, and by coupling genomics with evolutionary ecology experiments.
