2004 – 2008: University of Warwick, PPARC Studentship, PhD in Particle Physics

  • Title: Double Beta Decay with the COBRA Experiment. Supervisors: Dr. Y. A. Ramachers and Prof. P. F. Harrison
  • Developed a method for optimising passive shielding designs and applied it to the COBRA Experiment. Simulations were run using GEANT4 and MCNP.

  • Initiated development of an active shielding design for COBRA. Initially simulations were run but subsequent experimental work was conducted operating CZT crystals immersed in various liquid scintillators.

  • Experimental development work towards detector operation using the Frisch Collar method to improve energy resolution.

  • Data analysis work on “How many counts make a peak?” with regards to various peak finding algorithms applied to energy spectra.

2000-2004: University of Warwick, MPhys. (Hons) Mathematics and Physics, First Class
  • 3rd year group project: Superconductivity.

  • 4th year project: Magnetohydrodynamical Modes of Astrophysical Structures.
