Our aim within CHoSTM is to research and teach the histories of science, technology and medicine in ways that change understandings of their history, of history in general, and of the world in which we live today.  Our work has engaged directly with policy-makers and politicians and, just as importantly, has affected national and international conversations about science, technology and medicine. In 2023, we observed the 30th anniversary  of our research group, bringing together scholars (both past PhDs and staff) from various years.
