Research Interests
My research interests are in cell signaling from receptor
activation to transcription factor regulation. Effects of
environmental factors such as UV and arsenite on apoptosis or unwanted
growth/development are under cellular and molecular investigation by using
cultured cell lines or plant systems. Undergraduate research opportunities
exist in my laboratory.
