The Numerical Linear Algebra Group had a productive year in 2020, despite working remotely from March onwards because of the pandemic. 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.
Craig Lucas, Nick Higham, Xinye Chen, Steven Elsworth, Xiaobo Liu, Michael Connolly, Mantas Mikaitis, Len Freeman, Massimiliano Fasi, Pierre Blanchard, Sven Hammarling, Asad Raza Aitor Mehasi Mehasi, Stephanie Lai, Gian Maria Negri Porzio, Thomas McSweeney, Mawussi Zounon, Françoise Tisseur, Srikara Pranesh, Yuqing Zhang, Eleni Vlachopoulou, March 2020.
We make our research codes available as open source, principally on GitHub; see the repositories of Connolly, Fasi, Higham, Liu, Pranesh, Tisseur, and Zounon.
We also put MATLAB software on MATLAB Central File Exchange and on our own web sites, e.g., the Rational Krylov Toolbox (RKToolbox).
We welcomed new PhD students Xinye Chen and Thomas Seleiro.
Steven Elsworth successfully defended his PhD thesis Rational Krylov Methods and Machine Learning Approaches to Time Series Forecasting in March 2020 .
Michael Connolly took an internship with MathWorks from July to September 2020.
Postdoctoral Research Associates (PDRAs)
Mantas Mikaitis, previously an EPSRC Doctoral Prize Fellow in the group, is now working on the ICONIC project in the group. During the year he successfully defended his PhD thesis Arithmetic Accelerators for a Digital Neuromorphic Processor in the Department of Computer Science.
Massimiliano Fasi left the group in September 2020 and is now working at Örebro University in Sweden.
Roberto Cahuantzi was a member of the group from March to September 2020, working with Stefan Güttel.
