I am a graduate student in the UCLA Department of Mathematics. Currently, I am doing research on audio stream separation.

Some of my other research interests include:

Formalizing the "theory of patches" used by Darcs, a revision control system. My work so far on that subject is listed here.
Haskell, functional programming, and their use for numerical methods. I gave a talk on the subject in 2009, titled Functional Programming for Numerical Analysis.

Teaching

This quarter I am teaching PIC 40a. Here are some example files:

Another version of the lab 3 file which works better in Notepad can be found here.

Last quarter I taught Math 131A.

Previously I taught PIC 10a. Click that link to see examples from section and some information about using XCode.

TeX-related stuff

I am working on asciimath-tex, a LaTeX package for a more natural mathematical syntax, modelled on ASCIIMathML. See here for documentation and a bunch of examples.

A TeX puzzle:

The following lines of TeX each define \foo to "do nothing."
Which of the following definitions, if any, give \foo the same meaning?
For the rest, give examples of usage to show how they differ.

\def\foo{}
\def\foo{\relax}
\let\foo=\relax
\edef\foo{\ifodd1\else\fi}
