Giulia Hull has devoted her engineering career to a fascinating subject: the light emitted by particles. A scintillation specialist at IJCLab, she turns these faint signals into measurements physicists can use. She has designed and deployed detectors for many international experiments.

Her expertise now covers the entire instrumental chain, from the detector material to the measurement electronics. Convinced that discovery is a collective endeavour, she also works to structure the field. She co-leads the DI2I research group, dedicated to instrumentation for the two infinities. Since January 2026, she has been technical director of IJCLab, leading a division of more than 160 staff.
The CNRS Crystal Medal now rewards this commitment to scientific instrumentation. She receives the honour with emotion, true to her belief that every role counts in the adventure of research.
