My primary research interest is in digital media authorship and its potential to transform scholarly research and its expression, especially in the humanities. Most recently I have been focusing on how spatial media forms - maps, virtual worlds, games, and data viz - might converge in diverse, multimodal, immersive, shared hypermedia places and spaces. Some "test cases" include: visualizing the Great Exhibition of 1851, mapping the contemporary Muhuru Bay community in Kenya, exploring the development of cholera in Haiti, and modeling Duke and Durham, past and present. Most recently I have worked on Venice, Italy, with special attention to architecture and cultural transformation, and on augmented reality systems development. I also work on collaborative video game based art installations with the Psychasthenia Studio, and on curatorial projects with ACM SIGGRAPH (Special Interest Group on Computer Graphics and Interactive Techniques.)
