 In March 2013, Ben Elias and I gave a master
class on Soergel bimodules and KazhdanPolynomials.
Videos of all lectures are here. Lecture
notes are and exercises are available here.

In Feb '13 I gave two seminar talks and a colloquium at MIT about my
recent work with Ben Elias.

In March '12 gave talks at the Oberwolfach meetings
"Enveloping Algebras and Geometric Representation Theory" and
"Representations of Finite Groups". My talks were related, and
both reports are available here: Some applications of parity
sheaves, Checking
Lusztig's conjecture around the Steinberg weight.

The week of the 27th of February, 2012 I gave a six hour lecture series on parity sheaves at the winter school
Homogeneous Spaces and
Geometric Representation Theory in Bochum organised by St�phanie CupitFoutou and Guido Pezzini. Preliminary lecture notes are available here.

In June, 2011 I gave a three hour course on
localisation in equivariant cohomology at the University of
Melbourne at the invitation
of Arun Ram. Lecture
notes and exercise sheets are here.

In May 2011, I gave a four hour course called "KazhdanLusztig
polynomials and intersection cohomology complexes on the flag
variety" as part of a spring school Flag Varieties, organised by
C�dric Bonnaf�. Scans of the lectures and
slides are available here.

In 2011 I gave a number of talks about the
psmooth locus in a variety of locations (Jussieu, Newcastle,
Aberdeen). Notes of my talk (which contain a bit more detail
than the talk itself) are here.
Some pictures to illustrate what is going on.

In 2011 I have given a number of talks about
generators and relations for Soergel bimodules (Chamonix,
ClermontFerrand, BMC in Leicester,
Cambridge, Sydney, Ottawa, Amherst, Jussieu). Slides are here.
