Ilya's Homepage



I'm a software engineer at Belmont Technology, Inc., a CAD startup in Boston. Previously I was a researcher in computer graphics. My research interests span most areas of graphics, with a focus on geometry and applying discrete algorithms. I was a postdoc at Disney Research in Zürich. I did my Ph.D. in the MIT Graphics Group, working with Jovan Popović on making 3D modeling and animation more accessible to non-professionals. My master's was in the algorithms group, working with Erik Demaine. My email is "baran37 AT gmail DOT com".
