Research Interest :

Abiotic stress, including salinity, is a severe challenge in agricultural production. Our lab focuses on membrane protein's role in plant abiotic stress tolerance. We use structural and functional information of plant membrane proteins to understand and develop plant salinity tolerance. We also have interests in recombinant membrane protein/polypeptide production, purification, and characterization. Structure-based protein engineering is our third research direction, where we attempt to design, recombinant production, and characterization of engineered proteins with an evolved function.
