Research Interests

My main current interest is in developing equations of change that describe the motion of a granular material and the fluid that occupies its interstices, and using these equations in the solution of problems of practical importance, such as fluidized beds; standpipe flow and particle circulation systems; shear flows, chutes, and landslides; and transport of gas and particles in pipes. We have been successful in elucidating the structures that dominate the behavior of fluidized suspensions and in applying these insights to practical flows. At present attention is focused on developing numerical methods for direct solution of the equations in devices of practical importance.

I have also contributed to the fields of optimization, chemical reaction engineering, thermodynamics, and separation processes. For example, in collaboration with F.J.M. Horn, a simple mathematical criterion was derived that is useful in the search for reaction mechanisms that have multiple equilibria, or can support sustained oscillations, questions of some importance in biology. Our paper on this topic initiated the field now known as chemical reaction network theory.
