In the summer between her second and third year, she undertook a summer research project where she focused on geometrical optics, with an application to ultrasound imaging. Her final year project focused on caustics in geometrical optics. In her third year, she completed an 8-month research internship in the High-Tech Campus in Eindhoven, The Netherlands, where she worked in a laser lab on a circuitry printing technique known as LIFT. Outside of her studies, Jenny's main hobbies include Musical Theatre, photography, and watercolour painting.

### Seb Scott

Seb graduated from the University of Bath in 2020 with an MMath , where he developed a keen interest in numerical analysis. His Master’s dissertation on “efficient prior conditioning for edge enhancement in imaging” involved the regularisation of discrete ill-posed linear inverse problems.
