Research Area:

With the development of computational power and theoretical methods, computer simulations are playing more and more important roles in biological studies. We aim at revealing the function mechanisms of membrane proteins by using and developing multi-scale computer simulations, in collaboration with experimental studies. Our main interests currently involve permeation mechanism of ion channels, signaling through membrane-associated proteins, and interaction between antimicrobial peptides and lipid bilayers. In the mean time, we also try to contribute to membrane protein- or membrane-targeted drug design or optimization, and thereby to improve peoples health at large.
