Published research (1998-2012)    <----- updated 08/01/2012

I am the applied mathematician, working in the fields of PDE-based modeling and computation in materials science, crystal growth, and fluid dynamics.
This is also often referred to as physical applied mathematics and modeling. Correspondingly,  the dissemination of the results is primarily through the
mathematical physics, materials science and engineering journals. I have collaborators among researchers who work in these areas.

The common thread through my work is modeling and analysis of a thin film phenomena, such as the free surface/interface instability, wetting/dewetting, 
micro/nanostructure self-assembly and film patterning. Models of these phenomena usually result in a highly nonlinear, high-order parabolic PDE(s) for the 
shape of the film free surface or interface, which are derived from a governing free-boundary problem. I employ methods of the stability theory, perturbation
theory, nonlinear dynamics, and the numerical simulations. Analyses range from the more theoretical to more applied (where direct quantitative matching of
the model to the experiment is sought). As needed for modeling, I develop the 2D and 3D finite differences-based front-tracking methods.
