I teach laboratory physics at Bowdoin College, a job that I find both inspiring and fulfilling. This is a personal website where I put some of the other things that I like to do - photography, autocross car racing, amateur astronomy, and nerdy things. At least that's what I am building up to right now. Other things may come along from time to time.

BANNER: From work I did investigating dark matter. A foreground galaxy's gravity very slightly lenses the image of a background galaxy due to general relativity. By measuring shapes, one can characterize the lensing galaxy's gravity. Accordingly, it is necessary to know what lenses what.

Foreground galaxies are yellow dots, background galaxies are blue dots. Blue lines indicate that the galaxy is being lensed. Yellow lines indicate that the galaxy is lensing somebody else.
