Research Interests:
I am interested in several aspects of membrane transport in plants and how plants respond to environmental stress.
Projects that are currently being pursued include the control of sodium and calcium levels in plants exposed to saline
soils, the control of gene expression under salt stress, the transport of heavy metals into and out of plant chloroplasts
and the evolution of plants in response to the urban environment.
I am also involved in the genetic analysis of Theobroma cacao (chocolate) germplasm collections in collaboration with
Drs. Roland Roberts, James Saunders and the Cocoa Research Institute of the University of West Indies.
