Math Education

For the last three years, a major effort of mine has been my involvement with Epsilon and Delta Camps, where I am academic director.  The camps have been an important part of our family's life.  If you have or know a mathy elementary-school aged child, please have a look.

Beyond the camps, I have been thinking about mathematics and mathematics education for a long time.  The blogs linked below are in need of repair, but I hope to consolidate and modernize the presentation and make them available in the future.

  • Elementary Math Blog. Not many posts, but mostly decent quality.
  • An old general blog. Where you'll find much more, especially the twaddle.
  • SHG Math Club. I am organizing a Math Olympiad team for the Seattle Homeschool Group and post exercises and announcements here.

Sometimes I write software to help my kids explore certain concepts. Here are a few that may be of more general interest


I meddle in things academic from time to time. To see some artifacts of that interest, have a look at these links


I have worked for more than 10 years as a software developer on a variety of projects ranging from mining proteomic data to scheduling countertop fabrication. I love projects that have either clear value for users or stimulating mathematical or statistical challenges as part of the development. It's great when I find both. Once fun pet project I worked on a couple of years ago was a library for sensor calibration and data access from microcontrollers. You can peruse it here:

  • muCSense Git repository: an Arduino library for accessing and calibrating sensors.
  • A blog describing various algorithms for sensor calibration, how to access a variety of sensors, and detailed descriptions of the design and usage of muCSense code.
  • Code from this library and blog has been incorporated in DIY Drones and MHVLib.
