Ryan!

This is a picture of me taken in May of 2006.
If I look funny, it's because I'm in China.

Research

A nice supernova My research currently focuses on supernovae. Simply put, supernovae are exploding stars. The image on the left shows SN 2001V getting brighter and then dimmer.

Astronomy

What a GRB might look like Since Astronomy is such a large part of my life, it's nice to have some useful links on this page. But odds are they'll be quite boring if you're not an astronomer.

Classes

My thoughts on classes During my first and second years of grad school I both taught and took courses. I was once the Head GSI for Astronomy 10 (with Alex Filippenko). But currently I'm just researching. My notes are presented in both PostScript and DVI formats. When they are complete, I'll also put them in PDF. I might never complete my 201 notes. You'll want to view the DVI files for the most up to date version, but it'll be rougher than the PostScript file.
