George Gordon

I am an Assistant Professor in the Department of Electrical and Electronic Engineering at the University of Nottingham. My research is on optics, photonics and medical imaging. I develop new types of optical endoscopes that improve detection of diseases such as cancer. Prior to this, I was a Henslow Research Fellow at the University of Cambridge, where I designed and constructed a prototype holographic fibre endoscope that images optical intensity, phase and polarisation. This improves early detection of oesophageal cancer compared to conventional intensity-only endoscopes, as I demonstrated by imaging real diseased tissue samples. Further, the long (2m) and thin (500um diameter) geometry promises easier integration with existing clinical procedures, and paves the way for future imaging of previously inaccessible areas, e.g. the brain. I am also interested in low-cost imaging and currently hold two relevant grants: one to develop new capsule endoscopes for phase imaging of the oesophagus, and another to develop plasmonic metasurfaces for low-cost multispectral imaging.

My Ph.D., completed in 2013 at the University of Cambridge, was on wireless and optical fibre telecommunications, areas on which I have published widely. Through my research, I have gained proficiency in programming (MATLAB, C/C++, CUDA, Python), machine learning/data analysis (Monte-Carlo Bayesian inference through STAN, neural networks using Keras and TensorFlow), and optical design (e.g. digital holography, fibre and free-space optics, ZeMax).

Digital holographic creation of optical vortices, from my work on spatial mode-division multiplexing in optical fibres: (L to R) phase-only digital hologram, resultant mode amplitude, resultant mode phase profile.
