Technology: From 1997-2009, I ran BookFinder.com, the best resource (online or off) for finding used, rare, and out-of-print books; it was recommended everywhere from the Library of Congress to Entertainment Weekly. I eventually sold my company to AbeBooks / Amazon.com. Now I'm at UCSF's Clinical & Translational Science Institute, working on research networking, open source, and open data projects.
Environment: I spent 2009-2010 traveling around the world without flying, interviewing 60+ climate activists and researchers on 3 continents as part of my Year of No Flying challenge. In 2011, I helped organize a national speaking tour on aviation and the environment. I now tweet about aviation and climate justice.
Community: Closer to home, I co-curate the monthly Berkeley South Asian Radical History Walking Tour (celebrating 100+ years of immigrant heritage), build youth leadership with Bay Area Solidarity Summer, and support community resilience with the Alliance of South Asians Taking Action.
