About amit_chourasia:
Amit Chourasia leads the Visualization Services Group, TeraGrid Visualization Working Group and Advanced User Visualization Support at the San Diego Supercomputer Center (SDSC). SDSC is a national supercomputing facility funded by National Science Foundation(NSF) and is a Organised Research Unit at University of California San Diego. Amit's work is focused on leading the research, development and application of software tools for scientific visualization; for data typically generated by massively large computer simulations in various fields of science and engineering. Key portion of his work is to find ways to represent data in a visual form that is clear, succint and accurate (a challenging yet very exciting endeavour). He has had opportunities to work with research groups doing path breaking research in areas of astrophysics, biological sciences, climate modeling, computational fluid dynamics, nano technology, psychology, structural engineering and seismology. He believes that with the help of well done visualization domain scientists can gain significant insights and ask more relevant questions in addition to visual validation of their data.

Amit's research and application interests are in area of visualization, visual perception and computer graphics. He received a Master's degree in Computers Graphics Technology from Purdue University, West Lafayette and a Baccalaureate degree in Architecture(Honors) from Indian Institute of Technology, Kharagpur. He was the Co-Chair for the 2008 IEEE Visualization Design Contest. Currently, he is a reviewer for Euro Vis conference, member of Visualization and Graphics Technical Committee, program commitee member of International Symposium on Visual Computing, and Chair for the 2009 IEEE Visualization Design Contest.
