   Silberman has previously worked as a programmer in nonprofits and social enterprises and as a trade union official, and now works in a law school studying technology policy. Silberman’s practical experiences and some familiarity with literatures in human-computer interaction, sociology of technology, and technology policy will support our discussions. It is expected that Fellows also have diverse experiences and backgrounds. Fellows will be expected to bring these experiences into our discussions to reflect on, understand, and support one another’s ongoing work.
