Haydn Wadley’s research covers many aspects of the synthesis and processing of materials. At the fundamental level, he has conducted extensive research that identifies the thermo-chemical and micro-mechanical phenomena involved in the processing of materials. He has used this knowledge to develop models for the processing of metal matrix composites and the fabrication of cellular metals, and has coupled them with nonlinear control concepts to design optimal processes. Today he is heavily involved with the development of atomistic modeling methods, and is using them for large-scale computations of vapor phase transport in rarefied plasmas and for the simulation of atomic and molecular self assembly during the vapor deposition of metal and metal/metal oxide multilayers. He is the developer of numerous processing technologies several of which are being commercialized. They include two vapor deposition technologies (directed vapor deposition and energy modulated vapor deposition) and several processes for making cellular materials with truss lattice toplogies textiles, deformation shaped truss cores, polymer templated vapor deposition. Currently he is exploring the development of processes for the synthesis of multifunctional materials for energy storage and mechanical actuation. His sensor research has addressed many aspects of the interaction of elastic and electromagnetic fields with materials and has led to the development of numerous in-situ sensors. These include laser ultrasonic, acoustic emission, low frequency dielectric, microwave, luminescence and multifrequency eddy current sensors. They have been widely applied to processes ranging from the growth of II-VI semiconductor crystals to the continuous casting of steel. He pioneered the integration of advanced sensors, process models and feedback control concepts to create intelligent materials processing of materials (IPM) control systems. This technology is now pervasively used for controlling the processing of materials.
