"There are no shortcuts to any place worth going." - Beverly Sills
Manufacturing has been a big contributor to improved quality and sustainability of human life. My research goal is to advance the understanding and knowledge of Additive Manufacturing (AM) and to promote its wide applications in future engineering systems. AM is a a direct manufacturing process that has become a disruptive manufacturing technology, especially for medical and aerospace industries, in which small-quantity-production is dominant. It is predicted that AM will dominate most manufacturing concerns in future mass customization. To achieve the full potentials of AM on cost and time savings, the development of novel AM processes, new process control methods, and a wide selection of functional materials are critical. In addition, AM enables revolutionary new design by using complex three-dimensional shapes, heterogeneous material properties, and multi-functionality. Systematic knowledge regarding modeling, analyzing, synthesizing, and optimizing such designs are required to achieve desired performance.
At USC, our research group aims to develop AM technologies that enable people to revolutionize future product design and manufacturing. We are especially interested in Additive Manufacturing in micro-scale and meso-scale and the related design, modeling and computation methods. Since the AM-based digital manufacturing involves both physics-based manufacturing and computation-based design and control, we strive to address the challenges in AM research by fusing theoretical, computational and experimental knowledge with systematic thinking. This interdisciplinary research philosophy by tightly integrating both hardware and software sides of AM technology is at the core of my research group. We are currently working on the following three topical areas:
Novel process, material and machine development for functional additive manufacturing
New modeling and control techniques for accurate and reliable additive manufacturing processes
New design and computation methods for AM-enabled applications
