Gerassimos Orkoulas PhD

Assistant Professor

  • PhD Chemical Engineering 1998

    Cornell University (NY)

  • BS Chemical Engineering 1989

    University of Patras, Greece

  • ENGR 325 Thermodynamics

  • CHE 329 Transport Phenomena

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.
