Erika Jeannine Edwards is a professor at Yale University known for her work on evolution of plants. She is also the director of the Marsh Botanical Garden.
Edwards research focuses on succulents and the evolution of C4 carbon fixation in plants. Her early research centered on Pereskia where she examined its physiology and its place in the evolutionary history of cactus plants. Her research into C4 carbon fixation has examined how climate change alters the distribution of the C4 grasses and revealed that the C4 carbon fixation pathway gives plants an advantage in dry environments. Her subsequent research tracked the increase in C4 grasses with increases in tropical woodlands and savannas. Edwards led the working group which established the phylogeny of C4 grasses and defined the genetic differences across different types of grass. She uses changes in leaf shape to define how plants expend their resources during growth, examines plants' responses to changes in biome. and compares the parallel evolution of C4 photosynthesis and crassulacean acid metabolism.
