Susan Dudley, Ph.D. is a plant evolutionary ecologist at McMaster University in Hamilton, Canada, whose early work in plant kin recognition sparked both controversy and interest among many scientists. With a Ph.D. in Ecology and Evolution from the University of Chicago, Dudley joined the Biology Department at McMaster in 1995 and became a full professor in 2014, where she runs the Dudley Plant Lab.

One of her primary areas of research focuses on how plants sense the presence of other plants, and then respond, usually by producing a more competitive phenotype. Responses to cues of neighbors are thus important in competition. In addition to her work on plant interactions with other plants, Dudley’s lab also studies plant adaptation to abiotic stresses such as drought.

Dudley’s discoveries on plant kin recognition, an impossible notion according to many biologists just a decade ago, came from her research in the woodlands, beaches and subarctic regions of North America, which showed how plants change their shape and biomass allocation in the presence of other plants. Recently, researchers in China and elsewhere around the world have corroborated Dudley’s findings that plants do “recognize” kin and are researching the implications for agricultural use.

Dudley has authored dozens of academic papers and was featured in an episode of the nature documentary series “The Nature of Things” called “Smarty Plants.”
