Revision as of 23:45, 18 March 2010
I am currently a Graduate student at Rose-Hulman Institute of Technology pursuing my MECE (Masters of Electrical and Computer Enginnering) degree. My undergraduate degree was in Computer Engineering, also from Rose-Hulman. I am the Public Relations officer of the Rose-Hulman Linux Users' Group. I am working on another project using the BeagleBoard to control a walking four legged robot.
