José Luis Mascareñas, CiQUS researcher and former Scientific Director, served as Scientific President of the 2025 Bürgenstock Conference —becoming only the third Spanish scientist to hold this position in the six-decade history of the event. His role is particularly significant given the unique and highly selective character of the conference, which gathers each year around 140 participants in a secluded setting to discuss cutting-edge and often unpublished research across the molecular sciences. Among the invited plenary lecturers, in addition to the opening by Nobel Laureate David MacMillan; Erick Carreira, editor-in-chief of JACS; Andreas Pfaltz, pioneer in asymmetric catalysis and former Bürgenstock President; and Hagan Bayley, one of the inventors of DNA sequencing.
