Dr. Gravatt earned his B.S. in systematics and ecology ('88) and a M.A in botany ('91) from the University of Kansas. In 1994, Dr. Gravatt completed his Ph.D. from LSU. Dr. Gravatt maintains active research in the areas of how plants adapt to environmental stress. He use the understanding of plant physiology to elucidate the mechanisms of plant responses to different growth limiting factors. Adaptation of interest include physiological, biochemical, and morphological to such stresses. He is particularly interested in the environmental and biochemical limitations on photosynthetic capacity in stressful environments. An emphasis in the lab includes efforts to understand the physiology, morphology and anatomy of developing plantlets of the genus Sedum. The purpose of this work is to gain an understanding of how Sedum reproduces using vegetative propagules. In addition, he is interested in the physiological ecology of all species found on shallow soils through out the United States. Not all research is with succulent plants. His group
searchs for answers to questions relating to the physiological and
ecological adaptations of plants to stress. Such studies include
biochemical and morphological response to flooding, canopy level
physiology in loblolly pine stands, and physiological responses to
increases in atmospheric carbon dioxide concentrations. Dr. Gravatt teaches:
