It is with enormous sadness that we report here that Catherine Will, Professor of the Sociology of Science and Technology, at the University of Sussex, died on Monday 12th August 2024, at home, surrounded by her family. Catherine was a stalwart of the medical sociology community, and she will be greatly missed. We know that more details will be made available in the coming weeks about how we as a community can pay tribute to Catherine and her work, and we will be sure to share those details here.
