John D SiirolaDr. John D. Siirola is a Principal R&D Member of Technical Staff in the Analytics Department at Sandia National Laboratories. His main areas of expertise are systems design, operations research, optimization modeling, and optimization algorithms. Joh's research focuses on the intersection of computational tools with systems design and analysis; in particular, developing approaches for modeling highly structured systems, optimization algorithms that can exploit the expressed structure, and the application of these techniques to national security problems. Much of John's research is disseminated through open-source software projects. He leads the Acro project (optimization algorithms) and co-leads the Coopr project (optimization modeling). He is a core contributor to the Water Security Toolkit (modeling and analysis tools for drinking water distribution systems) and Dakota (optimization and uncertainty quantification), and contributes to numerous tools, including Utilib, PyUtilib, gcovr, and cxxtest. John has a B.S. from Purdue University (2000) and Ph.D. from Carnegie Mellon University (2005), both in Chemical Engineering. He is a senior member of the AIChE, member of INFORMS, and member of the COIN-OR Foundation. John currently serves on the COIN-OR Technical Leadership Council. He was also selected to co-chair the 2014 Foundations of Computer Aided Process Design (FOCAPD) conference. Read More Read Less
