Tiffin
Professor
Plant and Microbial Biology
Research in my lab is primarily focused on understanding the importance of symbiosis in shaping the evolution of legumes and rhizobia. I am also interested in the evolutionary forces that shape genomic variation and in evolution in urban environments. We use a variety of approaches including population genomics, coexpression network analyses, and empirical manipulations.
Research interests
Research in my lab is focused on understanding how biological interactions and environmental change affect plant evolution. We use a variety of organisms (including Zea, Clarkia, Arabidopsis, Medicago and Sinorhizobium ) and a variety of molecular and organismal approaches (including molecular population genetics, greenhouse and field studies, and quantitative genetics). I am involved currently in a variety of projects investigating i) the molecular evolution of plant immune system genes, ii) evolutionary responses to elevated CO 2 concentrations and other environmental changes, and iii) the ecological and evolutionary limits to species range expansion. I also remain interested in understanding the ecology and evolution of plant resistance and tolerance to herbivores and pathogens.
