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, for example, 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, for example, 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
