Lois Curfman McInnes is a senior computational scientist in the Mathematics and Computer Science Division of Argonne National Laboratory. She received a Ph.D. in Applied Mathematics from the University of Virginia in 1993.  Her research focuses on numerical algorithms and software for the parallel solution of large-scale scientific applications involving nonlinear partial differential equations and related optimization problems in the PETSc and TAO libraries.

Lois is co-lead of the IDEAS scientific software productivity project, which is working to improve software interoperability and the productivity of scientific software developers.  She is also a co-PI of the Frameworks, Algorithms, and Scalable Technologies for Mathematics (FASTMath) Institute, funded by the Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program.

Lois co-organized a 2011 workshop on Multiphysics Simulations: Challenges and Opportunities, sponsored by the Institute for Computing in Science (ICiS).   See a special issue of IJHPCA, Feb 2013.

Recent Projects: Lois was a co-PI of the SciDAC Framework Application for Core-Edge Transport Simulations (FACETS) and Community Petascale Project for Accelerator Science and Simulation (COMPASS) projects.  She was PI of a SciDAC-e project on Large-Scale Differential Variational Inequalities for Heterogeneous Materials, in partnership with the Center for Materials Science of Nuclear Fuel, an Energy Frontier Research Center.

Lois also was a co-PI of the SciDAC Towards Optimal Petascale Simulations (TOPS) Center for Enabling Technology.  She led the ‘Component Technology Initiatives’ thrust of the SciDAC Center for Technology for Advanced Scientific Component Software (TASCS).  She was a founding member of the Common Component Architecture (CCA) Forum, which developed a component architecture for high-performance scientific computing.

In 1988 Lois earned a B.S. in Mathematics and Physics, Summa Cum Laude, from Muhlenberg College, Allentown, PA.  Lois and her husband have two daughters.  Her extracurricular activities include yoga, participating in triathlons, and co-leading a Girl Scout troop and service unit.
