Dr. Economou's research focuses on the design, development, validation and application of state-of-the art models for the prediction of structure and physical properties of complex chemical systems that are of interest to oil & gas and chemical industry, to the protection of natural environment, and to the society, at large. Our models span a broad range of time and length scales, including: sub-molecular calculations using quantum mechanics techniques, molecular simulations using Molecular Dynamics and Metropolis Monte Carlo methods, and macroscopic engineering models such as equations of state rooted to Statistical Mechanics.
