B. Research interests.
My scientific interest is in structure and dynamics of liquids, liquid crystals,
molecular crystals and polymers. My research has included studies of simple
liquids (like chloroform) and complicated biological structures like 1-MDa capsid
of lumazine synthase.
During the last decade my research has focused on proteins, linear and
branched polymers (polycarbonates) , dendrimers, spherical nanoparticles. The
main “tools” for these structural studies have been the molecular dynamics and
mechanics using Materials Studio from Accelrys of San Diego and AMBER from
The Scripps Research Institute. In my research I have combined the information
obtained in X-ray , NMR and fluorescence experiments to model systems such
as: protein binding sites of ligands ( for instance: paclitaxel and colchicine in
tubulin, fluorolumazine in lumazine synthase), phenyl-polycarbonates showing
local ordering of their chains, and small molecules like cholesterol absorbed in
shell cross-linked spherical nanoparticles. The dynamics studies of these system
in several nanosecond time scale have become possible for me at the beginning
of 2008 when I obtained an access to the NYSGrid via the Center for
Computational Research at SUNY – Buffalo.
Since summer 2008 I have become involved in the computational studies of heat
flows in the composite thermal interface materials (TIMs). The tool for these
studies is LAMMPS Molecular Dynamics Simulator distributed by Sandia
National Laboratories. These simulations have been performed on NYSGrid and
TeraGrid.
