Darryl Yong (@dyong) is a mathematics professor at Harvey Mudd College (and former classmate of ours, also at HMC). He is working with HMC's Clinic Program, putting real industry projects in front of teams of college students. He's also teaching number theory to prison inmates and helping teachers in the chronically underfunded Los Angeles Unified School District.

Darryl writes about his career in education at Adventures in Teaching (profteacher.com). You can read about his experiences with the Inside-Out Prison Exchange Program.

If you dig into the archives a bit (2009) you can read about teaching at a high school, for example adapting teaching to different students. What he took away led him to create Math for America Los Angeles, a non-profit organization dedicated to increasing the number of secondary school mathematics and computer science teacher leaders in the greater Los Angeles Area.
