My research is in the areas of statistical mechanics and thermodynamics with applications in:
chemical engineering process design, heavy oil utilization, asphaltene characterization, sour
natural gas purification, supercritical fluid extraction/retrograde condensation, biotechnology, and
environmental pollution . We have developed: new molecular solution theories that are applicable
for engineering design calculations; phase equilibria theory of multicomponent mixtures, and we
have applied them to the case of polymer solutions, petroleum reservoir fluids, coal liquids, and
biological fluids; statistical mechanical mixing rules for asymmetric mixtures consisting of polar
and associating molecules such as aqueous; predictive techniques for supercritical fluid extraction,
retrograde condensation, and their applications in production and treatment processes of the
natural gas industry; phase equilibria for bioseparations and its applications for enrichment of
biological macromolecules (proteins) from biological fluids; and deposition and separation
techniques of asphaltene fractions from intermediate and heavy petroleum crudes and their
application in petroleum production and processing. In developing these techniques we have
applied experimental methods of chromatography, interfacial tensiometry, ebuliometry along with
fractal aggregation, colloidal, micellar, polymer, and statistical mechanical theories. For further
