Research Interests

Our group is interested in the study of biomolecular structure and dynamics, most of our research projects are related to drug design with the aid of nuclear magnetic resonance (NMR) together with many other experimental and computational techniques. Our recent research topics are summarized as below.

1. The study of allosteric effects in biomolecules. This research project mainly focuses on several proteins which already have allosteric sites discovered. Based on the dynamic property of different regions, the coupling mechanism between allosteric and active sites can be recognized, which could provide guidance for the discovery of allosteric sites in many other drug target proteins.

2. Drug design related to intrinsically disordered proteins (IDPs). IDPs do not possess well defined secondary structures under physiological conditions, therefore it is difficult to carry out structural related studies using experimental techniques such as X-ray crystallography. The dynamic property measured from NMR experiments is one of the few properties that can be learned for IDPs, which plays an important role in drug design related to IDPs.

3. The development of NMR pulse sequences. Although currently there are many NMR pulse sequences available for measuring different aspects of molecular properties, many experiments suffer from the issue of low sensitivity or artifact interference, therefore it still requires further optimization of existing NMR pulse sequences, as well as the development of novel NMR pulse sequences.
