My broad areas of interest are reaction engineering and optimization.
In reaction engineering, my major problem of concern is the interaction of chemical reaction and transport processes. The study of this interaction is especially important in the case of porous catalysts, and here the problem can get further complicated by various types of catalyst deactivation. For multiple reactions in porous catalysts, several optimization problems can be defined for these interacting processes, where the objective is the improvement of selectivity by partial impregnation or even by deliberate deactivation.
Other areas of research interest include non-ideal reactors, again especially in case of multiple reactions, and attempting to influence selectivity through various types of macromixing or micromixing patterns, and by the earliness or lateness of mixing.
As far as optimization is concerned, of special interest are variational problems, such as various optimal temperature and/or residence time policy problems for deactivating catalysts.
