Professor Piehler's materials research areas are in physical and analytical modeling of deformation processing systems and performance evaluation of mechanically fabricated components and products. His policy research areas are in productivity and innovation, plus the design of risk-management strategies and institutions.

Research in deformation processing and the mechanical behavior of materials, with special interests in sheet-metal formability and the properties of formed sheets; surgical materials and devices; powder metallurgy products; as well as composite and clad materials; standardization and regulatory processes; and engineering manpower utilization, productivity and innovation.

His current projects include studying the formability of aluminum sheets under controlled states of biaxial tension/compression and tension/tension deformation using the Carnegie Mellon University Sheet Metal Deformation Simulator. In addition he is involved in the physical and analytical modeling of powder and composites consolidation by hot isostatic pressing and hot triaxial compaction, a process developed at Carnegie Mellon University. Professor Piehler also conducts retrieval and analysis studies of orthopaedic implants and mechanical heart valves and in vitro evaluations of biomaterials and implants as well.
