Optimal keyboard layouts I algorithmically design keyboard layouts optimized for different languages (early example: engram.dev). I currently use a Bayesian preference learning model to convert crowdsourced typing preference data into estimates of typing comfort. |

Cave temple photodocumentation My wife and I created the first comprehensive photodocumentation of the Buddhist, Hindu, and Jain cave temples of Ellora in India, with a database of over 7,000 photographs referenced against ground plans (elloracaves.org). This work was partly funded by grants from the Mellon Foundation and the Indian government. Mapin and Columbia University Press will publish our book by the end of 2025. |

Information visualization database I built the database and website infovis.info back in 2008 as part of work on graphical taxonomies. You can still search for information graphics from a curated set of over 1.000 examples, including networks, cyberspaces, data visualizations, cartograms, etc. |

Holography Since the time I built a basement optics lab with a friend in high school to create holograms, I have been making display holograms and conducting research on 3-dimensional display technologies, at the University of Southern California, the University of Michigan, and at the MIT Media Laboratory. For my thesis work at MIT, I created the deepest dispersion-controlled viewing stations, and the thinnest edge-lit holograms, both of which use a hologram to present specially controlled light sources (pre-distorted wavefronts or pre-dispersed light) to a second, display hologram for sharper and deeper images. Since then, I have formulated a general raytracing equation for holograms. Holography has influenced my later research in surprising ways. |
