Background: Ph.D from University of Massachusetts, Amherst in Dr. Elsbeth Walker's lab studying roles of Arabidopsis YSL family in heavy metal transport and tolerance. Postdoc at Dartmouth College in Dr. Guerinot's lab focused on discovering genes involved in abiotic stress tolerance and nutrient storage during seed filling.
Research: Arsenic accumulation in both cereal and vegetable crops has been reported over the years, but the mechanisms of arsenic uptake, transport and storage in plants remain unclear. Understanding these mechanisms would be the key to breed crops with tolerance to arsenic stress and/or low levels of arsenic accumulated in the edible part. Currently, we are focused on identifying genes/QTLs involved in arsenic tolerance and arsenic accumulation in seeds through screening an Arabidopsis recombinant inbred line population.
