1990年至2000年获山东大学化学学士、硕士、博士。2000年至2003年在美国Brookhaven National Laboratory 和Argonne National Laboratory做博士后研究（Postdoctoral Research Associate）。2004年至今武汉大学化学与分子科学学院任教。
This laboratory is interested in both quantum mechanics and molecular mechanics. The major interest is to discover new chemistry in the filed of atmosphere, combustion, solution, materials, and biomolecules. Molecule geometries(bond structures, crystal phase, solvation structures), electronic properties (tensors, diople, polarization, hyperpolarization, charges, orbitals), spectral properties (UV, infrared, raman, NMR, CD, band structure, DOS), and reactions (mechanism, kinetics, dynamics) can be predicted theoretically with a high accuracy.
Theoretically, the efficient semi-empirical quantum chemistry methods have been developed to estimate the thermo-chemical data for gas, liquid, and solid. The specific property parameterized density functional theory has been developed for the simulation of chemical reaction and for the prediction of the chemical properties such as NMR chemical shifts.
The software we developed includes:
HEDM: a fast calculator for the high energetic density materials
DiDyn: a quasi-classical trajectory simulation software using on-the-fly ab initio methods for MD
WinDFTB: a semi-empirical tight-binding program running on windows platform.
RRKM-TST: a program to calculate the T, P-dependent kinetics for complex reactions.
Computationally, we use various quantum chemistry and molecular mechanic softwares to investigate the following chemical problems:
(1) The chemistry in solution
Electronic structures of the solvated molecules, depending on the temperature, the concentration, the pH, etc. can be simulated using first principle method. The solvated structure, IR/Raman spectra, diffusion, coordination number, and hydrogen-bond lifetime can be obtained theoretically.
The chemical reactions in solution is simulated using meta-dynamics. CPMD is the key software. VMD and JMOL for visualization.
(2) The interaction between small molecules and macromolecules
Using hybrid QM/MM methods, the interaction energy between the small molecules (guest) and the macromolecules (host) is calculated. The study is extremely useful for molecular design.
Softwares: Gaussian03, DFTB, Mopac, Amber, BOSS, Gromos, Gaussview
(3) Mechanism and kinetics of the complex chemical reactions
We are able to characterize the detailed reaction pathways by exploring the potential energy surface and the corresponding kinetic information such as rate coefficient and branching ratios for each product channel can be obtained straightforwardly. Besides the gas-phase reactions of interest in atmosphere and combustion, the solvent effect and the confined environments such as nanotubes can be simulated using various solvation models and QM/MM methods, respectively.
Software: Gaussian03, Molpro, RRKM-TST, Variflex, Polyrate
(4) Material simulation and surface reactions
This study is to discover the properties of the bulk materials at different conditions. The catalysis reaction mechanism can be obtained by simulation of the chemical reactions on the surfaces.
Software: MaterialsStudio (DMol, CASTEP, Discover)
(5) The other topics of our interest include: structure-activity relationship, electronic excited state, radical complexes.
