Some of my identities:

• I am the father of twins.
• I am a graduate of the History and Science program at Harvard, and the Technology in Education program at the Harvard Ed School.
• I am the Production Manager for MIT OpenCourseWare where I oversee the website [1].
• I also manage the MITx production team, which aids in the production of courses for edX and courses for use at MIT.
• Before working at MIT, I was the Director of Technology for the Interactive department at WGBH in Boston.
• I volunteer as the financial secretary at the First Lutheran Church in Waltham, MA.

I've made occasional edits to Wikipedia articles over the years, but I've never made a focused effort on editing articles, much less written one. A few articles that I'm considering working on:

• John Harrison
• Longitude
• Treatise on the Astrolabe
