A great many crops are deficient in genetic diversity as a result of extreme population bottlenecks resulting from domestication and breeding. This limits their capacity for adaptation to new or altered habitats and their resilience in the face of climate change. My laboratory studies the consequences of population bottlenecks for adaptation to harsh environments, merging approaches from genomics and evolutionary ecology. We also study ways in which genetics changes to crops or alterations to cropping systems can increase the amount of carbon sequestered in agricultural soils. We aim to develop a thorough understanding of the evolutionary ecology and population genetics of wild relatives of crops to breed better crops, conserve crop genetic resources, and build resilence to climate change into agricultural systems. We primarily work on legumes, with a focus on chickpea, lentils, fenugreek, fava bean and forages. We also work on grass-based production systems in Vermont.
