Abstract
Los Alamos National Laboratory (LANL) has been hosting the Los Alamos Dynamics Summer School (LADSS) since 2000. This program is an undergraduate research and education program designed to motivate top U.S. citizen engineering students to attend graduate school. Beginning in 2002 the LADSS concept was expanded into a more comprehensive education and research collaboration with the University of California, San Diego (UCSD), which is referred to as The Engineering Institute (EI). Working jointly with engineering faculty at UCSD the EI’s research has focused on integrating advanced predictive modeling capabilities with novel sensing systems and new developments in information technology. Our Institute has evolved to include a formal international partnership, The Engineering Institute-Korea, and we are now hosting Ph.D. students and postdoctoral fellows from several European and Asian countries. Realizing that a lot of research activities at LANL fall under the general heading of cyber-physical systems, in 2013 we plan to revamp the LADSS to focus on this topic in an effort to maintain LANL mission relevance. Similarly, many of the collaborative research projects with UCSD also can be classified as research related to cyber-physical systems and we plan to continue with this focus into the foreseeable future. This talk will summarize the Engineering Institute’s education and research activities with particular emphasis on their relation to cyber-physical systems. In addition to the LADSS we have developed a multi-disciplinary graduate degree program at UCSD that we believe trains students in a manner that better prepares them to address CPS research problems. As an example, in this program structural engineering graduate students are taking more than half of their classes in electrical engineering and computer science. Additionally, the collaborative research projects that we sponsor require faculty and students from electrical, mechanical, and structural engineering and computer science to work jointly on a project. All of these activities are motivated by our belief that the engineering leaders of the future will necessarily have to be more multidisciplinary and there are currently a dearth of programs that train graduate students in this manner. Also, included in this talk will be issues related to the understanding of cyber-physical systems as a research focus at LANL and new programs we are starting that will directly focus on cyber–physical systems research (e.g. our new Advanced Scholars Program). I will conclude the talk with a summary of challenges we have faced implementing these ideas, some of which we have not fully overcome.
