Research Summary

Plant Ecophysiology: Interactions between plants and the environment, Salinity tolerance, Heavy metal accumulation, Interactions with nanoparticles

My laboratory has examines salt and heavy metal stress in algae. We address questions of mechanisms of transport of relevant ions, including isotopic fluxes, electrophysiology, and biochemical and electrical analyses. We also explore mechanisms of resistance, especially with regard to heavy metals, both in ionic form and in the nanoparticles. We are also interested in the possibility of utilizing plants to clean up contaminated environments (phytoremediation). Our work has primarily been with Chara, an alga closely related to the line that gave rise to hirer plants, and which shows wide variability in salt tolerance. This species may be a useful source of information and genes to generate salt-tolerant crops, and is also currently used to clean up contaminated environments. We also do comparative studies on a distantly related green alga, Valonia, primarily in the field of salt tolerance and turgor regulation.
