Welcome to the Collegium
New Fellows Joined the 2025–2026 Cohort

As the Collegium community grows and evolves, so do the insights and perspectives that come together at the Semper Observatory. In this spirit, the Collegium welcomes several new fellows who joined our community in in the first months of 2026.

The new senior fellows include Odette Casamayor, Maria Dittrich, Dylan Millet, Mischa Suter, Brandy Toner, and Li Wan. Raquel Medina Plana will join us in March. In addition, we are pleased to host Tatiana Crivelli as the first sabbatical-at-home senior fellow. We look forward to many inspiring conversations and encounters.
