His current initiatives include the formation of the Global History Collaborative with colleagues in Berlin, Paris, and Tokyo.
In 2023, Adelman retired from Princeton and relocated to the University of Cambridge together with the Global History Lab whose Director he remains.
The initiative branched in September 2016, in collaboration with colleagues at the University of Geneva, to outreach programs to refugees in Kenya, Jordan, Rwanda and Uganda.
In 2020, it ceased to be a MOOC and became a network program shared across 25 institutions (universities, NGO's, foundations, and civic activist groups) in 23 countries.
Tens of thousands of students have completed GHL courses from Vietnam, Bangladesh, and Germany to Colombia, Greece and Nigeria.
