Annie Holden (University of Pennsylvania) — Cohomology of handlebody Torelli groups

We begin by introducing the Torelli subgroup of the mapping class group of a surface and outlining known results about its low-dimensional cohomology. We then present recent work extending these results to a Torelli subgroup of the mapping class group of a handlebody.
