Lois Curfman McInnes is a senior computational scientist in the Mathematics and Computer Science Division of Argonne National Laboratory. Her work focuses on high-performance computational science and engineering, with emphasis on scalable numerical libraries and community collaboration toward productive and sustainable software ecosystems. Lois has developed 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/TAO libraries. Lois serves as Deputy Director of Software Technology in the DOE Exascale Computing Project (ECP). She also co-leads the multi-institutional IDEAS project, whose members are partnering with the community to improve software productivity and sustainability as a key aspect of advancing overall scientific productivity.
Lois is a SIAM Fellow. She won the 2015 SIAM/ACM Prize in Computational Science and Engineering and received an R&D 100 Award in 2009 (with collaborators); she also won an E.O. Lawrence Award in 2011 (joint with Barry Smith) for outstanding contributions in research and development supporting DOE and its missions. She received a Ph.D. in Applied Mathematics from the University of Virginia and a B.S. in Mathematics and Physics from Muhlenberg College.
