My Commons user page, currently just a redirect here.

I am in my fifth year at Harvard University's math department, having graduated in June 2005 from The University of Chicago (with a degree in math, of course). Therefore every page I've significantly edited is on mathematics; I'm especially proud of my contributions to:

• Abel-Jacobi map
• Cayley-Hamilton theorem (I wrote the proofs)
• Exact category
• Knuth–Morris–Pratt algorithm
• Proj construction
• Mapping cylinder (I created this, but I can't claim any credit for the current version)
• Prime model
• Triangulated category (mainly the diagrams of the octahedral axiom)
• Zariski topology

I created, though I'm not sure if I should be proud of it, the page for Joe Harris.

You may be interested in a draft of Rational mapping that I have been planning to implement for a very long time. (I have now written Rational mapping based on this draft, but a little tidier.)

I am also writing an article on the Beauville-Laszlo theorem.
