Advanced imaging through optical fibres for cancer detection. (L to R) Hair-thin optical fibre with metasurface stack attached to end; Images of oesophageal tissue reconstructed through a 2 m long 500 micron diameter fibre using phase information to improve contrast between healthy and tumour tissue; Low-cost miniaturised capsule endoscope to enable advanced imaging for screening and triage.
I am an Associate Professor and UKRI Future Leaders Fellow in the Optics and Photonics Research Group, Faculty of Engineering at the University of Nottingham. I lead the OPTIMlab group, a team of 9 researchers working on optics, photonics and medical imaging, specifically developing new types of hair-thin optical endoscopes that improve detection of diseases such as cancer in hard-to-reach areas of the body. Achieving this relies significantly on several areas of research: digital holographic imaging and displays, artificial intelligence, nano-structured optical metasurfaces and clinical studies. Prior to this role, I was a post-doctoral researcher at the University of Cambridge where I built a fully holographic fibre endoscope and developed low-cost imaging techniques to improve early cancer detection. I received my Ph.D. in 2013 from the University of Cambridge on the topic of Wireless and Optical Telecommunications. I am an author of more than 30 peer-reviewed journal publications, on topics ranging from optical fibres to nanotechnology to reinforcement learning. 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).
