elloradaily Halloween!
Gallery
Once a year I take out 1-3 days to create a different identity. Most of these costumes don't last long, as they usually follow an edible theme.
elloradaily Ellora Time-lapse
ellora.org
I take a photograph of my daughter's face every day (not as consistently now that she's 15 years old!) and use facial features to coregister the images to create a time-lapse animation of her entire life. This project has been showcased in articles in the L.A. Times and Slate Magazine and has aired on Japan's NHK and Germany's DW-TV.
elloracaves Ellora Cave Temples
elloracaves.org
My wife and I collaborated with Professor Walter Spink of the University of Michigan to create the first comprehensive documentation of the Ellora cave temples of India. I took over 7,000 digital photographs of the Buddhist, Hindu, and Jain cave temples and have constructed an online "walk through" user interface to view the images with respect to the temple ground plans. This work was funded in part by a grant from the Mellon Foundation and several grants from the Indian government. We are now working on a book about the Ellora Caves!

I am the lead developer of Mindboggle, Python software for the analysis (feature extraction, labeling, and morphometry) of brain image data. The software has been used to prepare data for an international Alzheimer's challenge, has been funded by three NIH grants, and is under active development.
roygbiv Mindboggle's ROYGBIV brain image viewer
roygbiv.mindboggle.info
As part of the Human Brain Mapping 2015's Hackathon, Anisha Keshavan and I put together a browser-based, interactive brain surface visualization tool. Simple plots of Mindboggle shape measures accompany the anatomically labeled brain regions. This is under active development.
infovis Information visualization database
infovis.info
I created this searchable database of over 1,000 information visualizations to guide development of a taxonomic classification system for organizing and graphical language for symbolically representing such visualizations.
