Congratulations to Ben Stone, currently postdoctoral researcher in Dr. Carrie Wessinger's lab, on being awarded a three year NSF Postdoctoral Research Fellowship!  Ben's project integrates complementary methodologies (admixture mapping and genomic cline analysis) across natural replicate hybrid zones in Penstemon, a non-model adaptive radiation, to understand whether the genomic basis of adaptive trait divergence involves predictable features. These goals are pursued in two primary Objectives. Objective 1 integrates phenotypic and genomic data to map QTLs for adaptive floral divergence in separate hybrid zones involving secondary contact between distinct species pairs. Objective 2 identifies genomic regions associated with barriers to gene flow in hybrid zones and determines whether these regions correspond to identified floral QTLs.
