I am an experimental particle physicist, who has specialised in making precision tests of the Standard Model of Particle Physics. This includes measurements of quark-flavour physics and CP-violating interactions in decays of B meson particles (BaBar experiment, 1998-2009) and measurements of properties of the electroweak gauge bosons, Z and W (OPAL and MarkII experiments, 1985-2000). These allow stringent tests of our understanding of elementary particle interactions at the level of higher-order loop corrections in quantum field theory. I am currently working on the ATLAS experiment at the Large Hadron Collider, with an interest in the physics of the top quark.
