He has always been active in professional affairs and has held several leadership positions in professional societies. His technical responsibilities and research interests have been in the mechanics of materials for solids, structures and non-Newtonian fluids. He holds four patents, has written two books and 100 archive journal papers (nearly all single authored). These are on the following and related topics:

Properties of polymers (viscoelasticity)
Composite materials
Wave effects in heterogeneous materials
Low density materials (extreme porosity)
Kinetic crack growth
Life prediction and durability
Failure criteria for isotropic and anisotropic solids
