Research

Ben is a member of the Department of Applied Mathematics and Theoretical Physics High Energy Physics research group and The Cambridge Pheno Working Group based at the Cavendish Laboratory. He is a particle phenomenologist and is primarily interested in interpreting data coming from the CERN experiments in terms of new particles and forces. Then he tries to rule such new particles and forces out with other data. If this doesn't work, he asks what theoretical framework do they come from and can this explain unanswered mysteries.
