My role was as a research scientist at Rapiscan Systems, working on a number of varied projects including Pulse Pileup Processing for x-ray detectors and Magnetic Polarizability Tensor reconstruction using standard Metal Detectors.

London, United Kingdom

I completed a PhD at UCL in three dimensional x-ray imaging, using Time-of-Flight techniques to reconstruct the position of scattered photons. This project combines experimental work at specialist facilities, including the Versatile Electron Linear Accelerator at STFC Daresbury where I was the first user of the beam, simulation work, Monte Carlo (Geant4) and analytic (MATLAB & C++), and image reconstruction techniques.Whilst studying for my PhD I ran a workshop on Geant4 Monte Carlo Simulations at Rapiscan Systems.I have had collaborations with Rapiscan Systems, Atomic Weapons Establishment (AWE), Science and Technology Facilities Council (STFC), and University of Liverpool.I have been the collaborator on a successful funding application 'Time of flight X-ray imaging for security applications' (PI Paul Nolan, Uni. Liverpool) - http://www.stfc.ac.uk/2859.aspxMy research was included on the STFC website as a case study (http://www.stfc.ac.uk/3419.aspx)First Author Papers:N Calvert, et. al. 2014 'Feasibility Study of Time-of-Flight Compton Scatter Imaging Using Picosecond Length X-Ray Pulses' IEEE.

London, United Kingdom

Studied a 1 year MRes in Security Science at the UCL SECReT Doctoral Training Centre. The project examined the feasibility of using a Time-of-Flight technique to recover three dimensional information of an object under inspection (cargo container). The project mainly consisted of Monte Carlo simulations to further our understanding of the technique.

Stoke-On-Trent, United Kingdom

I am currently a Scientist working within the Engineering department at Rapiscan Systems Cargo Division.I work on Radiation Imaging & Detection systems; including High and Low Energy X-Ray Transmission Imaging systems, Radiation Detection (Gamma-Rays & Neutrons) and Low Energy X-Ray Backscatter Imaging systems.I am involved in both commissioning systems and Research & Development. My current position requires me to collaborate with many other areas of the company including Sales, Service & Software EngineersMy R&D specialities are Image Processing and Monte Carlo Simulations (GEANT4), whilst I work on Dual Energy Imaging & Gamma-Neutron detection on the Engineering side.I am also a qualified Radiation Protection Supervisor.

University Of Manchester Maths Department

Upon completion of my M.Math I continued my 4th year project on & undertook a feasability study on Gamma Ray Computed Tomography of Oil Pipes in a joint project between the University of Manchester & Tracerco, funded by VCIPT.I wrote a MATLAB based Image Reconstruction Algorithm to improve the quality of the CT images.I also suggested further improvements that could be made and other areas of research that needed to be undertaken in my final report.

Doctor Of Philosophy (Phd), Radiation Physics

Completed a PhD in Time-of-Flight x-ray imaging, combing experimental work with image reconstruction. Supervised by Prof. Robert Speller &.
