I am an experimental physicist in high energy particle physics. My current research projects are in association with the ATLAS experiment at the Large Hadron Collider at CERN near Geneva, Switzerland. Prior to coming to Oxford I was a researcher with the University of Pittsburgh doing research at the Collider Detector Facility (CDF) at the Fermi National Accelerator Laboratory, where my research was searching for, and then finding and studying, the B_c meson (a particle consisting of the bound pairing of a bottom quark and a charm quark).

Research interests

I have two research areas. At the forefront of Physics I am working with my students on data collected by the ATLAS experiment located 100 meters underground at the Large Hadron Collider at CERN just outside of Geneva, Switzerland. There, colliding protons act as the means to provide the high energy environment to turn Einstein’s equation E=mc2 on its head and use the energy from the power grid to try to create exotic states of matter than we have yet to discover. We look for pairs of Higgs bosons, and their decays into B hadrons (particles containing a bottom quark) as tags to find such exotic states should they exist. 

Find a recent article about this research on the University of Oxford's Department of Physics website.

My other area of research is in the construction of new types of sensors used to detect the passage of sub-atomic particles. I am involved in characterizing Pixel sensors and other components of data readout systems for their radiation hardness as the radiation environment near these high energy collisions is quite harsh.


Within Oxford I currently Lecture and tutor in circuit Theory for the first and second year courses. I also tutor quantum physics, 3rd year Special relativity and covariant electromagnetism, 3rd year sub-atomic physics, and first and second year calculus and linear algebra.

I also supervise Project students every year and usually have at least one graduate student working in my research areas.
