Lois Curfman McInnes » 'Home'


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.

Scientific software productivity and sustainability:  Lois is co-lead of the IDEAS scientific software productivity project, which is working to improve the productivity of software developers and the sustainability of software artifacts.  A key aspect of work is community collaboration to develop the Extreme-scale Scientific Software Development Kit (xSDK), which has the vision to provide infrastructure for and interoperability of a collection of related and complementary software elements—developed by diverse, independent teams throughout the high-performance computing (HPC) community.

Recent updates from the SIAM Activity Group on Computational Science and Engineering (SIAG/CSE):

Lois 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.

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.
