Research Focus

I am interested in how population history, population structure, and genetics and ecology of adaptation shape genetic diversity both within and among populations.  My research focus is in the area of plant molecular ecology, genetics, and evolution.  My work in the Jasieniuk lab includes introduction history and mode of spread of invasive plants and evolution of herbicide resistance in agricultural weeds.
