While I was a program director at NSF, I led the SI2 (Software Infrastructure for Sustained Innovation) program that had been created by Manish Parashar and Abani Patra, then was led by Gabrielle Allen, before it was my turn to shape it and lead it for about four years, from 2012 to 2016. This program initially funded projects that developed and maintained software, as well as projects that planned and built community institutes around software.
