Numerical Linear Algebra Group Activities 2019

The Numerical Linear Algebra Group had a busy year in 2019. This post summarizes what we got up to. Publications are not included here, but many of them can be found on MIMS EPrints under the category Numerical Analysis; see also these news stories about our publications.

Marcus Webb joined the group in September 2019 as Lecturer in Applied Mathematics.

Software

We make our research codes available as open source, principally on GitHub; see the repositories of ConnollyFasiHighamLiuPraneshZounon.

We also put MATLAB software on MATLAB Central File Exchange and on our own web sites, e.g., the Rational Krylov Toolbox (RKToolbox).

PhD Students

Massimiliano Fasi successfully defended his PhD Computing Matrix Functions in Arbitrary Precision Arithmetic in May 2019.

Postdoctoral Research Associates (PDRAs)

Massimiliano Fasi joined us in April 2019 to work with Nick Higham on algorithms for high-performance numerical linear algebra.  He was a Visiting Fellow at the University of Pisa from November 2019 to January 2020.

Mantas Mikaitis joined us in October 2019 on a EPSRC Doctoral Prize Fellowship, having just completed his PhD in the School of Computer Science.

Pierre Blanchard left the group in May 2019 and is now a Numerical Software Engineer at Arm.

Maksims Abalenkovs and Theo Mary left the group in September 2019. Maksims is now a Research Software Engineer with the Science and Technology Facilities Council and Theo is a CNRS researcher at LIP6 in Paris.

Grants

Stefan Güttel, Nick Higham and Françoise Tisseur were awarded a new 30-month KTP project with Arup.  See this news story.

NLA Group Partnering with Arup on Next Generation Structural Engineering Software

KTP Arup.png

Dr Stefan Güttel, Professor Nick Higham, and Professor Françoise Tisseur have been awarded a new 30-month project with Arup, a multidisciplinary engineering firm operating in all areas of built environment.

This Knowledge Transfer Partnership (KTP), funded by Arup and Innovate UK, aims to embed new matrix eigenvalue solvers into Arup’s next generation software for structural engineering simulation.

The Numerical Linear Algebra  (NLA) group team will be working with Dr Stephen Hendry and Dr Ramaseshan Kannan of Arup, along with a KTP Associate, for which the position is advertised here.

The project builds on a long history of collaboration between Arup and the NLA Group, which has  previously led to the development of “model stability analysis” in Arup’s flagship structural engineering simulation package, Oasys GSA (see the paper What is Your Structural Model Not Telling You?).
