Jedediyah Williams
Hi! I am a STEM teacher at Nantucket High School. I was previously the Science Department Head (2008-2010) and Mathematics Department Head (2014-2017).
In 2019 I was named as a finalist for the Presidential Awards for Excellence in Mathematics and Science Teaching. In August 2020 I was named as the Massachusetts awardee in Mathematics.
In 2017 I was a finalist in the NASA Space Robotics Challenge (Team Whalers).
In 2013-2014 I worked with Lockheed Martin on the DARPA Robotics Challenge (Team TROOPER).
In 2011 I was awarded a National Science Foundation Graduate STEM Fellowship in K-12 education and worked with Prof. Ron Eglash and Prof. Mukkai Krishnamoorthy on the Culturally Situated Design Tools.

This playful title was granted annually to a UMass Amherst computer engineering major for the best (most efficient) PIC implementation of a challenge algorithm. My winning strategy was to simply double the memory space required, which saved a clock cycle with each swap of values in an array.
