As an occupation, I'm a mathematical physicist, studying string theory and quantum field theory.

I've developed as a hobby a few Cocoa (Touch) apps. The largest one so far is spires.app, which manages articles and metadata downloaded from the arXiv eprint server, the inspire database, and the journal websites.

I'm also interested in many other things, which is why I ask questions in various StackExchange sites ...
