Research Interests
Research in stress ecophysiology and morphology of plant species subjected to air toxins, elevated CO2, heavy metals, water stress, and temperature stress. Also, research interests in designing and conducting large-scale experimental studies of interacting stresses, and how they alter carbon uptake and allocation. Recent interests involve the investigations of genotypic variability in response to stress, and how this relates to improving mitigation strategies.
