## Lois Curfman McInnes

The scalable solution of nonlinear partial differential equations (PDEs) arises in many scientific and engineering applications. Lois and her collaborators develop algorithms and software for the scalable solution of PDEs in the Portable, Extensible Tookit for Scientific computation (PETSc), which provides robust, efficient, scalable, and extensible tools that are the backbone of numerous high-performance applications. PETSc is an object-oriented numerical software library that has put the power of parallel computing in the hands of a wide range of scientists.

Lois’s research focuses on the numerical solution of nonlinear PDEs on high-performance computers; scientific applications involving PDEs, with emphasis on multiphysics contexts; and issues in software interoperability for large-scale scientific computing.
