Deep learning for image reconstruction in lithium-ion battery Bragg coherent diffractive imaging
BSc Natural Sciences dissertation · UCL Department of Physics & Astronomy
First-class (76%) literature review and computational study on the use of deep learning for image reconstruction in Bragg coherent diffractive imaging of lithium-ion battery cathodes. The dissertation surveys the limits of conventional iterative phase-retrieval algorithms (HIO, ER, RAAR) on noisy, low-photon-budget BCDI data, and reviews the emerging neural-network reconstruction work that bypasses iterative inversion altogether.

2014–15
Year-long programme running a real student business end-to-end. First serious experience of operating outside a classroom; left with a habit of asking who the customer is before anything else.

Sport has been the constant: discipline, training cycles, and a tolerance for being wrong in front of other people.
