Peter Stern is a Manager in the Product Policy Group at Facebook in Menlo Park, California. Product Policy is responsible for writing and interpreting global policies governing what users can share on Facebook, and how advertisers and developers interact with the site. Mr Stern leads a risk management team within this group that seeks to ensure Facebook has the proper policies and enforcement practices in place, and is aligned with key external stakeholders such as NGOs and governments. Mr Stern’s work puts him at the centre of many current Internet policy issues — including the scope of free expression, anti-bullying and -hate speech, safety in cyberspace, and user trust. Prior to joining Facebook in 2014, Peter was a litigation partner at the San Francisco law firm of Morrison & Foerster, where he specialized in intellectual property matters and spent 11 years in his firm’s Tokyo office. His practice also included human rights litigation and counselling in the area of corporate social responsibility (CSR).
