Exploring the Radio Universe
As an associate scientist at the National Radio Astronomy Observatory (NRAO), I study the dynamics of galaxies in the Universe by using a variety of telescopes. I use the 305-m Arecibo, 100-m Green Bank, Very Large Array radio telescopes (above), IRAM 30-meter, and Palomar Hale Telescope to study the dynamics of these galaxies near and far.
In additon, I'm fascinated by the current revolution in astronomy dealing with large datasets. I write software dealing with the visualization and mining of these datasets at radio frequencies. I work on some of the calibration pipeline software for our telescope arrays. I've also worked on the Green Bank Telescope data archive, and the Very Large Array calibration pipeline.
I'm interested in studying and working with 3D graphics. The animation above is a 3D volume rendering of the velocity field based on data from the PSCz catalogs (Saunders et al. 2000 and Schmoldt et al. 1999).
I've published a book on 3D graphics and visualization in the sciences.
