Lois Curfman McInnes
Senior Computational Scientist, Argonne National Laboratory | Lemont, Illinois, U.S. 

Job Description:
 Investigate numerical algorithms and software (in the PETSc library) for the parallel solution of large-scale scientific applications involving nonlinear partial differential equations and related optimization problems, with emphasis on high-performance multiphysics simulations. / Lead work on mathematical libraries in the DOE Exascale Computing Project (ECP), featuring collaboration on the Extreme-scale Scientific Software Development Kit (xSDK), which is working toward a software ecosystem for high-performance numerical libraries. / Improve developer productivity and software sustainability in the IDEAS software productivity project

Other Positions: Worked in the Mathematics and Computer Science Division of Argonne National Laboratory in various capacities since initial appointment in 1993, as a DOE Distinguished Postdoctoral Fellow.

Education: B.S. in Mathematics and Physics, Summa Cum Laude, Muhlenberg College   /   Ph.D. in Applied Mathematics, University of Virginia   /   SIAM Fellow 

Possible Lecture Topic and Audience: Applied Math and Computational Science at DOE Labs (+ My Career Path) / Undergraduate math majors and beyond 
Possible Lecture Topic and Audience: Toward Community Software Ecosystems for High-Performance Computational Science / Undergraduate math majors and beyond

Geographical Constraints: Logistics would be easiest within driving distance of Rockville, MD or Argonne National Laboratory. Would prefer to bundle trips to other locations with other business travel, due to job and family logistics challenges.
