Research Interests

We would like to dramatically improve crop yields by increasing drought-, heat-, and salt-tolerance in transgenic crops through the use of biotechnology. We are also studying the functions of plant protein phosphatase 2A (PP2A), especially its role in plant response to abiotic stresses such as drought, salinity, and extreme temperatures. Furthermore, we are studying the molecular mechanism of protein targeting to peroxisomal membranes by characterizing a molecular chaperone (i.e. AKR2A) that regulates the biogenesis of some microsomal and peroxisomal membrane proteins.
