• Environmental systems engineering
• Constitutive theory development
• Continuum Mechanics
• Fracture Mechanics
• Experimental Stress Analysis
• Mechanical Engineering Design

• Use of the statistical design of experiments and Taguchi techniques to optimize the design of mechanical systems.
• Incorporate cost and environmental factors into the design optimization process.
• Development and evaluation of relations for the degradation of residual strength and stiffness of composite materials.
• Influence of cyclic loading on the degradation of residual strength and stiffness of composite materials.
• Development, evaluation, and comparison of constitutive relations for inelastic material response.

In the solid mechanics and material science area he has taught undergraduate and graduate courses in statics, material science, materials engineering, continuum mechanics, theory of elasticity, and fracture mechanics. He has also taught a number of mechanical engineering design and computer-aided design courses at the undergraduate and graduate level. He has been principal or co-principal investigator of eleven research grants and contracts involving the development of new experimental techniques for nonlinear fracture toughness testing, determining the effects of biaxial applied loads on the fracture process, and the development of new optimization procedures in mechanical engineering design and computer-aided engineering. He has directed approximately twenty-five Master of Science theses and Doctor of Science dissertations in these areas. Recently, he has employed optimization techniques to improve the sustainability of the product development process. He has completed approximately seventy journal articles and conference publications, and has presented another twelve conference papers.
