    Biography

    Our research interests in a broad sense are to understand the biological functions of certain proteins from their structural point of views. Particularly, we focus on structure-function relationships of metalloenzymes, as well as protein-protein interaction and protein-ligand interactions that are related to signal transductions in cells. Our long-term goal is to translate these basic research studies into the discovery of new drugs and therapeutic methods to treat human diseases.

    Our research interests are in the following areas:

    1. Regulation of Nitric Oxide Synthesis in Bacterial Nitric Oxide Synthase (NOS)
    2. Receptor and Protein Interactions in NO Signaling
    3. Structure-function Studies of Heme O2 and NO Sensors
    4. Mechanism of NOS-related Endothelial Dysfunction
