At Georgia Tech, we're seeking PhD candidates wishing to study data visualization via a variety of disciplines <http://vis.gatech.edu>. Our six faculty within Computing conduct research on a variety of related subtopics including information visualization, visual analytics, enterprise computing, data mining, network analysis and healthcare analytics, among others. We offer two doctoral degrees: a PhD degree in Computer Science (CS) and a PhD in Human-Centered Computing (HCC) <http://www.cc.gatech.edu/future/doctoral>. The CS PhD <http://www.cc.gatech.edu/future/doctoral/phdcs> is a relatively traditional computing-focused doctorate where students specialize in a particular area of computer science such as HCI or Computer Graphics. Students must pass a comprehensive exam in the area, take 3 courses outside CS for their minor, and complete a dissertation. Georgia Tech founded the very first HCC degree program <http://www.ic.gatech.edu/future/phdhcc> in 2004, focusing on the intersection of computing and people - where computing includes not just computers but also different kinds of computational artifacts from games to mobile applications, from robots to bionics and mobile applications; and people includes not only individuals but also teams, organizations, societies and cultures. The HCC Program values diversity in all its dimensions; our students have a broad range of backgrounds, coming from across the world and with a variety of different undergraduate degrees. The program's curriculum <http://www.ic.gatech.edu/future/phdhcc/program> is flexible, allowing considerable customizing based on individual interests: three core courses, three specialization courses and three minor courses. In both programs, students receive tuition and a competitive stipend during their studies; outstanding US students are additionally eligible for the President's Fellowship ($5500 per year for four years). Applications are due December 15; see <http://www.cc.gatech.edu/future/doctoral/phdcs/admissions> and <http://www.ic.gatech.edu/future/phdhcc> for additional program and application information. PhD admissions are committee-driven and selected; individual faculty do not accept students.
