  • My brother Mathew, plays guitar for the progressive rock band SummerPint jUNkie. If you own/work for a record-label and would like to sign them on please get in touch with me! :-)

  • Things I like: bushwacking, cooking, climbing, Unix pipes, picking colors/styles/designs, people, Lego, manual work, asymmetry, symmetry, taking and organizing mental notes, HOT water/tea/soup, lying in bed doing nothing, tulips, orange juice, Tintin, getting things done

  • ... and things I don't: concurrent multitasking, uncomfortable seating, acronyms, sweet food (except ice-cream), getting late, entropy, staring at glowing screens like this one ...

  • I'm involved with instructing Upper Valler school students at robotics camps conducted by Dartmouth College and the Hanover town library. See, for example, this one.

  • Bouldering at local crags with John Joline '70.
