The current research of Dr. Shew’s lab is focused on elucidation of the self-assembly structure of aggregated macroions and the role of long-range electrostatic interactions in these self-assembly processes by using theoretical approaches. The systems under investigation include intramolecular self-assembly of a giant DNA and like-charge attraction between highly charged metal oxide ions, etc. The theoretical works of Dr. Shew’s lab have been extended to understand several existing experiments, such as the spatial configuration of a histone in a chromosome, self-assembly of highly charged metal oxide nanocluters, and high efficient gene delivery systems by use of amphoteric polyions. Meanwhile, his group has successfully developed a robust simulation algorithm that can be utilized to analyze the novel spin echo small angle neutron scattering spectra, a new neutron scattering method with great potential in characterization of the complex structure of self-assembled aggregates.
