During my PhD I've given a handful of talks at the SPAAM Seminar, organised by the Warwick SIAM Student Chapter, and have collected the recordings of them here.
If you have any questions regarding the content of the talks please feel free to email me at a.nugent@warwick.ac.uk and if you have any technical problems accessing the recordings please email siam@warwick.ac.uk (who maintain the YouTube channel).
Lots of recordings of other great SPAAM talks by researchers at Warwick can be found here!
