This publication consists of colorful data sheets on the National Science Foundation's Engineering Research Centers (ERC) Program, a program designed to strengthen the competitiveness of U.S. industries by bringing new approaches and goals to academic engineering research and education. The main elements of the ERC mission are cross-disciplinary and systems-oriented research, education and outreach, and industrial collaboration and technology transfer. Data sheets on each of the 20 ERCs are grouped into the following technological areas of emphasis: biotechnology and bioengineering; design and manufacturing; infrastructure; materials processing for manufacturing; optoelectronics: microelectronics and information technology; and resource use and recovery. Each data sheet typically includes the Center's name, associated institution, area of major emphasis, a summary of the research being done, summary of educational activities, summary of efforts in industrial collaboration/technology transfer, description of facilities, director's name, address, e-mail address, phone and fax numbers.
