STPF groups are formed and managed by current and alumni fellows. They provide a forum to meet and discuss issues related to areas of targeted interest, including various areas of science, policy, and other topical issues. Affinity group activities range from presentations and discussions with expert guest speakers, to monthly meetings and gatherings over coffee, workshops, full day symposia, and multi-day conferences. Social groups do not necessarily reflect the views of AAAS, its Council, Board of Directors, officers, or members. Social groups are available as a public service, but this does not constitute endorsement by AAAS.
