FIRST Robotics
I am an active volunteer for FIRST, a non-profit organization that provides grade-school students around the world with hands-on STEM education opportunities through robotics competitions. I am an alum of FIRST Robotics Competition Team 1533 Triple Strange, and credit my experience with FIRST as a high school student for pushing me to pursue the field of robotics and my current line of research. Since graduating, I have volunteered at every level of FIRST as a referee. I am the co-creator and developer of the FIRST Tech Challenge Scoring System, FTCLive, that provides live scoring and event management for all FIRST Tech Challenge events.
