I am a fifth year Ph.D student working with David Speyer.
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. Here are some gln word crystals, and
here is a link to my math blog.
I would love to
talk to you about: GL_n representation theory and Schubert calculus,
flags and
Grassmannians, Hilbert schemes and related moduli problems (such as
moduli of curves), homological
algebra, and other "concrete" algebraic geometry
and commutative algebra.
Prior to working in geometry, I wrote an undergraduate thesis with Steven
J. Miller on Lfunctions and random matrices.
(This makes me part of the Miller Mafia). I also did commutative algebra
at SMALL with Susan
Loepp in 2009; we constructed a class of strange
singularities and studied them analyticallylocally.

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).

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.
