Who We Are: SNL Phoenix Core Group
A core group of Sandia National Laboratories scientists and engineers started investigating complex systems literature across many domains in 2003 and initiated complex adaptive systems analyses the following year. This group began formally developing the theoretical bases of the CASoS Engineering Initiative in 2006. Some early adopters have moved on to carry the conceptual seeds into the larger Sandia population, to other disciplines and program areas. Others have joined the initiative bringing new perspectives and skill sets to continue the evolution of this problem definition and solution design process. Teams form and reform in response to project characteristics.
Robert J. Glass is a Senior Scientist at Sandia National Laboratories in Systems Research, Analysis, & Applications. He directs the Complex Adaptive Systems of Systems (CASoS) Engineering Initiative. Dr. Glass has degrees from Haverford College (BS, Ecology) and Cornell University (MS and PhD, Agricultural and Biological Engineering). He worked for many years in the general field of Subsurface Science where his discoveries of phenomena and creation of new modeling approaches influenced problems ranging from water and contaminant transport in fractured rock (e.g., Yucca Mountain, Nevada) to the remediation of aquifers contaminated with Dense Non-Aqueous Phase Liquids (DNAPL such as TEC and PCE). Joining the National Infrastructure Simulation and Analysis Center (NISAC, a joint program between Sandia and Los Alamos National Laboratories for the Department of Homeland Security) in 2004, Dr. Glass has grown a research team that focuses on the analysis and control of CASoS as embodied by many critical infrastructures and socio-economic-technical systems.
