In the Classroom

The Internet has made significant impacts on education. Vast information can now be much more easily obtained from the web compared to earlier years. To make the classroom experience unique, Professor Cao integrates recent developments in manufacturing research and development into the classroom, including review of the state-of-the-art new process innovations developed around the world, and invites external speakers from academia and industry to address the class. The integration of mechanics with manufacturing is also a must in her instruction. 

Professional Service

Prof. Cao has been active at the national and international stages. She served as the program director of the Materials Processing and Manufacturing (MPM) program at NSF from 2003 to 2005. During that short two-year period, under her leadership, the World Technology Evaluation Study on Micromanufacturing was conducted and co-sponsored by four government agencies and more than ten NSF programs. She co-initiated the joint-funding between NSF and DOE for her MPM program, which has been continued strongly after her departure. She is one of the main driving forces behind the well-received NSF workshops on CAREER development. Dr. Cao is active in professional societies, served as president of North American Manufacturing Research Institute of Society of Manufacturing Engineers, chair of ASME Manufacturing Engineering Division, chair of Scientific and Technical Committee on Forming of International Academy of Production Engineering (CIRP), and vice-chair of Additive Manufacturing Working group of CIRP.
