Laura Grigori

Laura Grigori is a French-Romanian applied mathematician and computer scientist 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 of Sorbonne University.

Education and career Grigori earned her Ph.D. from Henri Poincaré University in 2001. 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 .

After postdoctoral research at the University of California, Berkeley and the Lawrence Berkeley National Laboratory, she became a researcher for INRIA in 2004, and became the head of the Alpines project in 2013. In 2021, she will join the SIAM Council as a Member-at-Large.

Recognition A 2012 paper on communication-avoiding algorithms for parallel matrix decomposition by Grigori with James Demmel, Mark Hoemmen, and Julien Langou won the 2016 Society for Industrial and Applied Mathematics (SIAM) Activity Group on Supercomputing Best Paper Prize for the best paper on parallel scientific and engineering computing from the previous four years.

Grigori has been an invited plenary speaker at many international conferences on scientific computing. In 2020 Grigori was named a SIAM Fellow "for contributions to numerical linear algebra, including communication-avoiding algorithms".
