Research Overview
We are carrying out theoretical/computational works on numerous
important topics in physical, material, and biophysical chemistry.
The molecular reaction dynamics and control theory are studied
for photodissociation of small molecules, focusing on the
effects of quantum interference. The physicochemical properties
of biomolecules are theoretically treated. The effects of
the solvent molecules on the structures and reactions of amino
acid - water and DNA base - water clusters are examined. The
properties of their electronically excited states are calculated
to help analyze their experimental spectra. Electronic and
optical properties of semiconductor - biomolecule interface
are also studied by employing various theoretical tools.

Director: Professor Yongho Kim (yhkim@khu.ac.kr)
Research Overview
Our main research topic is theoretical studies for reaction
dynamics of multiple proton transfer. The direct dynamics
approach has been used to generate potential hyper surfaces,
and the variational transition state theory including multidimensional
semiclassical tunneling approximations is used to calculate
rate constants and tunneling coefficients. The multiconfiguration
molecular mechanics method is used to generate potential energy
surface for large molecular systems. Other research topics
in our lab are bioinfomatics and protein dynamics. We are
interested in the pKa of the amino acid residues in an enzyme
active site. The QM/MM method is used to study the acidity
of amino acids and the environmental effects.
