My research is in the general area of reaction engineering and energy, in particular steam reforming and hydrogen production. A strong component of this work is the use of scientific computing methods to investigate transport and reaction in chemical reactors and porous media. Scholarly work is currently being carried out in computational fluid dynamics (CFD) studies of fluid flow through beds of particles and heat transfer in fixed-bed reactors. I have also participated in engineering education, teaching, and learning, with particular interest in the use of mathematics and computing within the chemical engineering curriculum.
