We use population, association (GWAS), and quantitative genetic approaches to understand evolutionary process shaping diversity in natural populations.

A major focus of current research is association and population genomics of the model legume Medicago truncatula as well as the rhizobial symbionts (Ensifer / Sinorhizobia) of this plant. Using whole-genome sequence data we have been investigating the genetic basis and genetic architecture of phenotypic variation, the genetic basis of local adaptation, and how selection has shaped diversity at genes responsible for phenotypic variation and local adaptation.
