One focus of our research is on the development and application of strategies for reliable engineering computing. In many applications of interest in chemical engineering it is necessary to deal with nonlinear models of complex physical phenomena, on scales ranging from the macroscopic to the molecular. Frequently these are problems that require solving a nonlinear equation system (algebraic and/or differential) or finding the global optimum of a nonconvex function. Thus, the reliability with which these computations can be done is often an important issue. For example, if there are multiple solutions to the model, have all been located? If there are multiple local optima, has the global optimum been found? If there are uncertain parameters and/or initial conditions in a dynamic model, have the effects of these uncertainties been rigorously quantified. We are using interval mathematics to develop the tools needed to resolve these issues with mathematical and computational certainty, thus providing problem-solving reliability not available when using standard methods.
Another research focus is the formulation and solution of modeling problems that arise in the development of sustainable, energy-efficient and environmentally-conscious processing technology. Of particular interest is the use of room-temperature ionic liquids (ILs) as environmentally-benign replacements for traditional organic solvents and refrigerants, and as sorbents for CO2 capture. Also of interest is modeling the impact of new materials and technology on potentially affected ecosystems.
