Laura Grigori is a French-Romanian applied mathematician and computer scientist [1] known for her research on numerical linear algebra and communication-avoiding algorithms.
She is a director of research for the French Institute for Research in Computer Science and Automation (INRIA) in Paris, and heads the "Alpines" scientific computing project jointly affiliated with INRIA and the Laboratoire Jacques-Louis Lions [fr] of Sorbonne University.
Her dissertation, Prédiction de structure et algorithmique parallèle pour la factorisation LU des matrices creuses, concerned parallel algorithms for LU decomposition of sparse matrices, and was supervised by Michel Cosnard [fr].
[5] Grigori has been an invited plenary speaker at many international conferences on scientific computing.
[1] In 2020 Grigori was named a SIAM Fellow "for contributions to numerical linear algebra, including communication-avoiding algorithms".
