Biography & Education
My group at K-State is focused on the genomics of climate adaptation in sorghum and its relatives. Our goal is to develop genomic knowledge and tools that accelerate the development of climate-resilient crops.
We map genes that underlie climate adaptation and develop new approaches to understand and predict adaptation. We also work directly with breeding programs in the US (Kansas and Texas) and developing countries (Senegal, Niger, Haiti, and others) to facilitate development of new better-adapted sorghum varieties.
I am originally from Canada and received my undergraduate training in Biology at University of Ottawa. My doctoral work at University of Chicago (Ecology & Evolution) was focused on analysis of genomic variation, to understand how gene expression is controlled across environments. I turned my focus to crop genomics during my postdoctoral research, first to the emerging bioenergy crop switchgrass at University of Chicago, then to sorghum starting at the University of South Carolina as a Research Assistant Professor. I've been run the Sorghum Genetics lab at K-State since 2013.
