This page lists global online events (free and open to anyone) as well as open online events by local GUIS chapters. Global events are of four types:

• a "life stories" series, in which one speaker with a science PhD (usually a faculty member) tells their life and career story with an emphasis on struggles, doubts, failures, and detours;
• a themed series on anti-racism in academic science;
• a themed series running series on mentorship in academic science;
• Open Forums, for open discussion about personal struggles and how to make academia better.
