WorldWide Telescope project, processing terapixel astronomical images and data for global perusal.
Visualization Developer, Adler Planetarium and Astronomy Museum. Creating Python/Perl libraries for developing movie flight paths in Partiview and using them to create full-dome and 3d stereo movies of astronomical phenomena.
|Fall 2004 - Fall 2006 ||Research
Assistant, Department of Computer Science, University of
Chicago. Working in Gina Levow's
and Intonation project. Applying information theoretic and machine
learning methods such as Support Vector Machines and
Max-Margin Structured Learning to large
sets of sequential prosodic information. Typically use C++, Matlab, Perl and Praat.
