Is an expert on air flow instabilities in engines. Has developed technology to help quiet jet engine noise. Is director of Purdue's Center for Bladed Disk Unsteady Aerodynamics Research and Technology. Research interests include combustion, turbulent reacting flows, flame radiation, combustion and heat transfer in material processing and pollutant reduction. Research interests include mechanical behavior of materials, fatigue and fracture, aging aircraft and biomechanics of the skeletal system.
Research focuses on jet propulsion systems and design.
Has performed noise control and smart material research and consults for a number of companies. Research also involves developing and studing methods to adopt cooperative learning methods to large, traditionally lecture-style courses. Research interests include optics, optical or laser-based measurements, engineering instrumentation and biomedical instrumentation. Specializes in mechanical behavior, design and remodeling of biological tissues, effect of stresses on remodeling and tissue engineering. Has won numerous teaching awards.
