Dr. Joy Ward is interested in understanding how global change factors influence the physiology, population structure, and evolution of plants.

Research Interests

My research program aims to incorporate the effects of physiological and evolutionary responses of plants to environmental change, particularly changes in atmospheric CO2 concentration. I strive to explain these responses at the molecular, physiological, and evolutionary levels, since an understanding of primary mechanisms are critical for accurately predicting plant responses to future global change scenarios. Furthermore, by incorporating plant responses to past global changes that are recorded in the fossil record, my research provides unique perspectives into how plants may respond to long-term changes in the availability of fundamental plant resources. Such findings will be highly relevant to predicting the trajectory of plants in response to anthropogenic changes in [CO2] and climate, and for determining how to best sustain and conserve our current ecosystems.
