Mainly, I am interested in Modular
Representation Theory, and spaces with a $G$-action.
Especially modules arising from $G$-actions on
spaces, their restrictions to
subalgebras of $k[G]$ and their interaction with
the fixed point sets of the subgroups of
the group acting on the space their cohomology
via localization theorems in cohomology
are among my main intrests.
Besides, the support variety of a module is a
favorite topic for me.
Many of the rings coming out of groups such as
the group ring, cohomology ring,
representation ring, character ring, Burnside
ring together with their interactions
are sources of excitment for me.
I also work on $p$-power points and modules of
$p$-power Jordan type that
I introduced as a generalization of $p$-points
of Friedlander-Suslin-Carlson-Pevtsova,
for finite abelian $p$-groups. In my most recent
paper I have given a nice filtration
of modules of constant Jordan type.
