Research
I am primarily interested in algebraic geometry and algebraic
combinatorics. My current research involves Schubert
calculus, equivariant free resolutions and moduli of stable curves.
For example, here is a combinatorial covering
space called a 'Schubert curve', and
some related Young tableaux. And here are some gln word crystals. Papers

I also taught two mini-courses in July 2014: An introduction to Schubert Calculus: 5-days, notes here: Intro 1 1.5 2 3 4 5. Translating between geometry and algebra: 5-days (taught jointly with Rebecca RG). Recent and upcoming talks
Personal:I graduated from Williams College with a BA in mathematics, and spent Fall 2009 in Hungary at the Budapest Semesters in Mathematics program, which I highly recommend. If you're a Williams student thinking about applying to math grad schools, feel free to get in touch! I can't guarantee to be helpful, but I can guarantee to be more helpful than either of these guys.I am Canadian. More specifically, I am from Montreal, Quebec. I love bagels and occasionally poutine, et je parle français (mais je suis anglophone / English is my mother tongue). Undergrad Thesis:Download my undergraduate thesis and accompanying Mathematica
notebooks: downloads page Qual Solutions:I wrote up my solutions to the May 2012 Analysis QR Exam, since there are currently no solutions to any analysis quals... that made it hard to study! Download here. |
