Numerical Linear Algebra Group Activities 2022

During 2022 the Numerical Linear Algebra Group introduced a new logo, designed by Massimiliano Fasi, former PhD student and Research Associate in the group.

We published interviews with alumni Younes Chahlaoui and Vanni Noferini.

In addition to our papers in journals we published articles in SIAM News:

and a book

The award of the ACM A. M. Turing Award to Jack Dongarra was a highlight.

PhD Students

Zhengbo Zhou started as a PhD student, working with Nick Higham and Françoise Tisseur.

Xiaobo Liu (Computing Matrix Functions in Arbitrary Precision Arithmetic) and Michael Connolly (Probabilistic Rounding Error Analysis for Numerical Linear Algebra) successfully defended their PhD dissertations. Michael is now working as a data scientist at Bet365.

Postdoctoral Research Associates (PDRAs)

Xiaobo Liu and Bastien Vieuble took up PDRA positions towards the end of the year to work with Nick Higham.

Mantas Mikaitis left the group to take up a lectureship in the School of Computing at the University of Leeds on September 1st. He joined us in 2019 to take up his EPSRC Doctoral Prize Fellowship and he was a PDRA in the group from 2020.

Conference and Workshop Organization

Sixteen members of the Group attended a two-day creativity Workshop held in April 2022, facilitated by Dennis Sherwood, an expert in creativity. See this report on the workshop.

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.

Recognition and Service

Jack Dongarra received the 2021 ACM A.M. Turing Award.

Nick Higham was elected Fellow of Royal Academy of Engineering.
