Research Interests:

• Development of new methods for the synthesis and processing of materials

• Analysis of complex engineering systems with the aid of models and simulation

• Application of chemical reaction engineering principles to interdisciplinary problems. The following areas are of particular interest: Mechanical-Chemical interaction in solid phase reactants; Cooperative behavior or mesoscale: solitons and solitary wave; Thermal stresses and crack development in chemically reacting system; Development of high temperature acoustic detection methods; Piezoelectric sensors, manufacture and modeling; Chemical reaction and natural convection; Analysis of thermal CVD systems, e.g. - the effect of the flow field on the deposition rate and film homogeneity; Dynamic stress development of films during deposition; Reaction-induced thermal stresses in consolidated media; Mechanical failure of catalytic systems during thermal cycling or transient operation; The study of nonlinear dynamical systems, e.g. - existence of temporal chaos and solitary waves; Bifurcation analysis of non-catalytic highly exothermic reacting systems; Development of fast thermocyclers for polymerase chain reaction (PCR) ; Theoretical investigation of errors in the polymerase chain reaction process; Assembly of DNA structures from synthetic oligonucleotides; Strategies for Gene Packaging in Virus-Like Particles.
