Plenary talks will be given by: David L. Donoho (Stanford), Stephen J. Wright (Wisconsin), David J. Brady (Duke), Yi Ma (Illinois), Joel Tropp (CalTech), Remi Gribonval (INRIA), Martin Vetterli (EPFL) Francis Bach (Laboratoire d'Informatique de l'E.N.S). In addition to the above eight plenary speakers we welcome all working on sparsity related topics to join us and present their work. We will have slots available for 66 speakers and a poster session for those that cannot be accommodated in the talk schedule. Speakers will be selected based upon submitted one page extended abstracts which are due by April 1st 2011. The event is subsidised by the EPSRC, LMS, ICMS, ECoS, and INRIA. Registration fees are 70 GBP for doctoral and masters students, and 140 GBP for faculty, postdocs, and industry representatives. Registration due by May 15th 2011.
