RESEARCH INTEREST: (Present and past)


o   Biomimetic: Conformation and dynamics of protein and tethered membranes: the structural relaxation and pathways to stabilities and multi-scale mode dynamics. Residues mobility, energy, and correlations profiles of peptides.

o   Chain polymer: Polymer chains in solvent, porous media, complex fluid, and on surfaces. Driven flow response. DNA electrophoresis.

o   Branched polymer: Kinetic gelation, Sol-Gel phase transition, micro-emulsion and lipids, percolation, and aggregation.

o   Multi-component materials: Nano-clay-polymer composites, biofunctionalized nano-structured materials (involving peptide attached gold, palladium, and montmorillonite clay platelets).

o   Surfaces, interfaces, and roughness: Surface, roughness and interfacial dynamics in thin film growth with a range of constituents (particles, polymer chains, solvents)

o   Driven transport and flow: Flow through porous media, Self-organizing structure and flow multi-component complex systems.

o   Immune response: Population dynamics of cells.

o   Econophysics: Theoretical modeling of stock fluctuations.

o   Critical phenomena:  Thermal and geometrical phase transition.



o   Chaired three MS theses in Physics (Song-Ping Gao, Sai Yu, Yan He) until several years ago when we adopted different tracks for MS degrees resulting in nearly no students with thesis options since then. The MS tracks have been changed again recently.

o   Chaired six Ph.D. dissertations (Grace M. Foo, Yimin Liu, J.L. Becklehimer, Luis Cueva-Parra, Frank Bentrem, Shihai Yang) in “Scientific Computing” now “Computational Science”.




Methods used in teaching and research: Computing and visualization in general.  Computer simulations methods: Monte Carlo, Molecular Dynamics, Lattice Gas, Hybrid Methods involving Hydrodynamic and Micro-scale. Multi-scale computing with nano, micro, macro-scale issues.  Early work involved analytical theories such as Mean field, Many-Body, Scaling, and Renormalization group methods.


CONFERENCE & MEETINGS: I have consistently presented invited and contributed talks in major international and national conferences and meetings. We presented about 5-10 talks per year in last 20 years.
