Not for publication

In Winter 2014 I passed my topic exam, on representation stability and applications to arithmetic statistics, under the supervision of Benson Farb. The proposal is here.

In Spring 2012 submitted my undergraduate thesis, on a free DGLA model for the 2-cell, under the supervision of Ruth Lawrence. The thesis is here.
