Seminars and notes
Rational points on curves: A padic and computational perspective. Oxford, 24  29 September (2012) I coorganised (with Henri Darmon, Minhyong Kim and Alan Lauder) a workshop focussing on methods for studying rational points on curves, especially from a padic and computational perspective. This focus included StarkHeegner point constructions and methods from anabelian geometry, as well as related topics such as padic Lfunctions and padic modular forms. The conference website can be found here, with notes from all the talks. A picture of (most) participants. Deformation week Oxford, 16  19 April (2013) I coorganised a workshop on aspects of deformation theory, April 2013. The workshop was aimed at graduate students from different fields, interested in applying techniques from deformation theory in their respective fields. The webpage is here. Perverse sheaves and the decomposition theorem Oxford, Michaelmas 2014 Balázs Szendrői and I ran a perversity seminar, the webpage can be found here. JacquetLanglands and cyclic base change Oxford, Michaelmas 2014 Minhyong Kim, Andrew Wiles, and I ran an automorphic seminar, the webpage can be found here.
