Personal profile

Born in Birmingham, U.K., in 1987. He received the MSci degree in Physics from Royal Holloway, University of London, Egham, U.K., in 2010. He first did a summer placement at National Physical Laboratory, Teddington in 2009. This was with the Time, Quantum and Electromagnetics Division on the detection of ultrasmall particles using a Hall sensor. He is now doing a PhD in Physics at National Physical Laboratory and in collaboration with Royal Holloway, University of London.

Research interests

My interests lie in novel non-invasive nanoscale magnetometers. Hall sensors can be used in biomedical and information technology industries.  In these fields, a precise knowledge of magnetic properties on the nanoscale is required. My goal is to design, fabricate, analyse and optimize submicron size semiconductor and graphene devices for magnetic field detection. The detection of small magnetic moments is possible due to high sensitivity of the Hall sensor. Conventional Hall sensors are semiconductor based, but a recent development in graphene allows us to look into this physical 2DEG system. Noise measurements on these devices are used to determine the minimum field sensitivity.
