The Manchester Numerical Linear Algebra group was very active in 2015. 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.
Software
We continue to make our software available. Increasingly this is done on on GitHub: Deadman, Higham, Relton, Sego, Tisseur, Zhang. 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
New PhD student Matthew Gwynne joined the group in January 2015, sponsored partly by Arup.
New PhD students Massimiliano Fasi (supported by a Presidential Doctoral Scholarship), Jundong Li (supported by The MathWorks), and Mante Zemaityte, joined the group in September 2015.
Mario Berljafa and Weijian Zhang served as Treasurer and Webmaster, respectively, of the Manchester SIAM Student Chapter, 2014-2015. For 2015-2016, Weijian Zhang is President, Mante Zemaityte is Vice President, Matthew Gwynne is Secretary, and Mario Berljafa is treasurer. Massimiliano Fasi is webmaster.
Postdoctoral Research Associates (PDRAs)
Scott Ladenheim joined the group as a PDRA in August 2015. He is working with Milan Mihajlovic in the School of Computer Science.
Mary Aprahamian became a PDRA in October 2015 after submitting her PhD thesis.
Edvin Deadman moved to a position with NAG (Manchester) in May 2015.
Leo Taslaman moved to a position with COMSOL (Stockholm) in August 2015.
Jennifer Pestana moved to a Lectureship at the University of Strathclyde in October 2015.
Vanni Noferini moved to a Lectureship at the University of Essex in September 2015.
Vedran Sego worked with Francoise Tisseur, September–October, 2015.
