Congratulations to Chris Hickey for wining a bronze medal at the 2023 STEM for Britain in the Mathematical Science category for his poster Seismic Simulations: Implementing and Improving a New Dynamic Structural Analysis.
This work was accomplished when Chris was a Research Associate on a Knowledge Transfer Partnership (KTP) between the University of Manchester and Arup Ltd. Chris implemented and improved MASIL, a method for dynamic structural analysis developed in the NLA group (F. Tisseur and M. Zemaityte) in collaboration with Arup (R. Kannan).
STEM for Britain is an exhibition of posters by early-career research scientists, engineers and mathematicians that takes place every year in the Houses of Parliament during British Science Week.
The full list of this year’s winners is here.
Congratulations to Professor Nick Higham, who has been elected an International Member of the US National Academy of Engineering. The citation reads “For design and analysis of matrix algorithms widely used in diverse engineering applications”.

Mantas Mikaitis and Nick Higham organized a double minisymposium Understanding and Exploiting Mixed-Precision Accelerators for High-Performance Computing at the SIAM Conference on Parallel Processing for Scientific Computing (PP22) in February 2022. Slides of some of the talks are available.
The conference Advances in Numerical Linear Algebra: Celebrating the 60th Birthday of Nick Higham was held at the University of Manchester, July 6–8, 2022, organized by Stefan Güttel, Sven Hammarling, Stephanie Lai, Françoise Tisseur and Marcus Webb. Most of the talks are available on the NLA Group YouTube channel and links to them are available on the conference web page. Photos are available here.
Jack Dongarra received the 2021 ACM A.M. Turing Award.
Nick Higham was elected Fellow of Royal Academy of Engineering.
Stefan Güttel was awarded the 2023 ILAS Taussky–Todd Prize.
Stefan Güttel was reappointed for another term as a member of the SIAM Membership Committee, 1/1/2023–12/31/2025.

Professor Stefan Güttel has been awarded the Taussky–Todd Prize by the International Linear Algebra Society (ILAS).
The ILAS Taussky-Todd Prize is given every three years at an ILAS Conference to an outstanding mid-career researcher in the field of linear algebra, for distinguished contributions to the field within about fifteen years of receiving the PhD or equivalent degree.
The 2023 ILAS Taussky–Todd Prize honours Professor Güttel’s “deep and impactful work on rational Krylov methods for nonlinear eigenvalue problems and matrix functions, in all aspects: analysis, software development, and applications”.
The prize is named for Olga Taussky and John Todd, who had a decisive impact on the development of theoretical and numerical linear algebra for over half a century. It honours them for their many and varied mathematical achievements and for their efforts in promoting linear algebra and matrix theory.
Professor Güttel will deliver a prize lecture at the 25th ILAS Conference in Madrid, 12 to 16 June 2023.
Congratulations to Professor Nick Higham, who has been
elected Fellow of Royal Academy of Engineering, in recognition for developing
“theory, algorithms and software that have had major impacts on
engineering practice in fields ranging from structural engineering to
financial modelling”.

The Numerical Linear Algebra Group recently held a competition amongst its members to design a logo for the group. Chosen from among four excellent entries, the winner was designed by Max Fasi, former PhD student and Research Associate in the group and now an external member of it.
The logo contains a matrix with a sparsity pattern that depicts a bee, the symbol of the city of Manchester since 1842. The bee symbolized the hard work of Mancunians during the industrial revolution.
You’ll see the logo on our slides and our social media accounts, and perhaps on physical items in due course.
Congratulations to Jack Dongarra who has received the 2021 ACM A.M. Turing Award. He is cited “for pioneering contributions to numerical algorithms and libraries that enabled high performance computational software to keep pace with exponential hardware improvements for over four decades.”
Dongarra has been Turing Fellow in the Department of Mathematics since 2007, and also holds appointments at the University of Tennessee and Oak Ridge National Laboratory.
In summer 2021 the NLA Group organized a workshop New Directions in Numerical Linear Algebra and High Performance Computing: Celebrating the 70th Birthday of Jack Dongarra. Videos of talks, including one by Dongarra, are available here and provide much insight into Dongarra’s career and achievements.
The photo below shows Dongarra speaking at the 2019 Manchester workshop Advances in Numerical Linear Algebra: Celebrating the Centenary of the Birth of James H. Wilkinson. Wilkinson, seen at the top eight-hand corner of the slide, won the Turing Award in 1971.

Professor Françoise Tisseur has been awarded the London Mathematics Society’s Fröhlich Prize for “her important and highly innovative contributions to the analysis, perturbation theory, and numerical solution of nonlinear eigenvalue problems”.
The Fröhlich Prize is awarded even two years in memory of Albrecht Fröhlich, FRS. The prize is awarded for original and extremely innovative work in any branch of mathematics.
The full prize citation is available here.
Professor Nick Higham is featured in the June 2020 issue of The Actuary Magazine, the magazine of the Institute and Faculty of Actuaries.
In an interview with the editor, Dan Georgescu, Nick talks about his development in 2002 of his nearest correlation matrix algorithm, which is widely used in finance and data science.
The magazine is freely readable on the Issuu platform.
More details about the nearest correlation matrix problem and algorithms for solving it are available on Nick’s blog.
