Ben Allanach is a member of the Department of Applied Mathematics and Theoretical Physics High Energy Physics research group and The Cambridge SUSY Working Group based at the Cavendish Laboratory.

Ben is a particle phenomenologist, and is primarily interested in interpreting data coming from the CERN experiments in terms of new particles and new physics, in particular supersymmetry, higgs bosons, dark matter. He is also interested in linking up this data with other astrophysical and cosmological data, and in developing statistical techniques required to do so. He retains an interest in neutrino physics.
