My primary interest is introductory programming and computation. I am also interested in programming languages and software testing as well as tools and technologies for massive collaborative information organization (sometimes called human-assisted computation) such as Wikipedia, last.fm, Find A Grave, and ancestry discovery and verification through research coupled with DNA analysis.
