Notes
These are some brief notes and graphics to illustrate the correspondence between string motions and automorphisms of the free group.
Topic Exam
I took my topic exam at the University of Chicago in February 2011. My topic proposal is available here: The Cohomology of Configuration Space and Representation Stability.
Undergraduate Projects
I received my B.Sc.H. from Queen's University in Kingston, Canada.
In the summer of 2009, I took part in a project on Littlewood Richardson Coefficients and Coxeter Groups with Mike Roth and Ivan Dimitrov, with the support of an NSERC USRA. My colleagues completed our project the following year: Decomposing Inversion Sets of Permutations and Applications to Faces of the Littlewood-Richardson Cone (with R Dewji, I Dimitrov, A McCabe, M Roth, and D Wehlau).
In the summer of 2008, I took part in a project on Free Probability and Random Matrices with Roland Speicher and James A. Mingo, supported by an NSERC USRA.
Some of our work is available here: The non-commutative cycle lemma. (with C Armstrong, J A Mingo, and R Speicher.)
