Current Directions:

Investigate the mechanism behind the lipid-dependent effects on voltage-gated potassium (Kv) channels and the connection to lipid metabolic defects in human. We discovered strong inhibitory effects of nonphospholipids, such as cholesterol and glycosphingolipids, on Kv channels, and are studying their roles in the sever neurological diseases caused by lipid metabolic defects. ary to infection and immunity our lab has an active interest in improving oocyte cryopreservation and the developmental environment of the early embryo.

Understand the molecular basis of a granin family protein in every step of the regulated secretory pathway, and the importance of these proteins in the impaired secretion in human diseases, such as type 2 diabetes, as well as their importance to the metastasis and survival of human neuroendocrine cancer cells.

Structural and functional studies of membrane proteins and intracellular RNA-binding complexes and their relation to human diseases including cancers and neuroendocrine defects.
