Dr Omar Anchassi is an Islamicist with wide-ranging interests in premodern and modern Islamic intellectual history, including but not limited to the history of science (especially astronomy), Islamic law, theology, and Qurʾānic studies. He is part of the SNSF-financed research project TraSIS (PI Prof. Dr Serena Tolino, 2022–2026).
His contribution to TraSIS focuses on the historical development of the legal categories of the umm al-walad, mukātaba and kafāla in non-Sunnī juristic thought. In addition to his research for TraSIS, Omar has recently (Jan. 2026) submitted a habilitation thesis exploring Muslim debates on the structure and configuration of the cosmos in the longue durée.
