Research interests

My research focuses on visual ways to interact with data and mathematical models. I sometimes call this direct manipulation 2.0. For example, Math Easel and Graph Sketcher let users visually manipulate quantitative data and ideas. And TeraFractal features an interface for directly and intuitively adjusting fractal parameters. I am interested in using this approach to take digital textbooks and reference works to their logical conclusion: interactive applications for learning, exploring, and referencing each area of study.


Projects

  • Math Easel: Interactive, web-based calculators and simulations. (2012- )
  • Vizable: Dramatically easier data analysis for touch screens. (2013-2016)
  • TeraFractal: A visual interface for creating lifelike fractals. (2005-2012)
  • Graph Sketcher: Fast, simple graph drawing and data plotting. (2003-2011)
  • Pidgin Parser: Extendable, semantics-driven parsing of "notes to self". (2007)
