About Me

I strongly believe that students should mediate between science as taught in universities and its uses in everyday life. They should not only gain a fundamental understanding of the course material, but more importantly, they should also be able to apply the new knowledge to practical, real-world problems.

To this aim, my teaching has focused on practical applications of taught theories to allow the students to obtain and apply the necessary problem-solving skills that can be used throughout their entire careers. Seen from this point of view, my teaching is an ongoing attempt to allow students to discover and reflect on their potential and constantly improve themselves.

I have mentored seven doctoral students and five undergraduate students in research projects. Furthermore, I have been awarded three highly competitive research grants ($1,000,000 by the National Science Foundation (NSF), $150,000 in research fellowships, and $170,000 in equipment).

Research Interests

My research interests are in the area of mathematical modeling, simulation, optimization, and control of multiscale physico-chemical process systems and in the area of thermodynamic modeling and molecular simulation (Monte Carlo, molecular dynamics and kinetic Monte Carlo) of complex fluids.

My specific research areas include: modeling and simulation of multiscale process systems Detailed process description using conservation laws and stochastic model construction Parameter estimation from microscopic/mesoscopic simulations; model-based control and optimization of multiscale process systems Model reduction, coarse-graining, and predictive control of distributed parameter systems Dynamic optimization over multiple length scales; molecular simulation of complex fluids Monte Carlo, molecular dynamics, and kinetic Monte Carlo methods Development and optimization techniques for parallel codes using domain decomposition.
