### Matthew Pawley

Matthew graduated from Imperial College London in 2020 with an MSci in Mathematics. While at Imperial he developed an interest in statistics and completed projects on a range of topics, including stochastic modelling of retail systems, MCMC for Bayesian inference in astrophysics, and classifying the qualitative behaviours of spherical orbits around Kerr black holes. In his Master’s thesis, he developed a machine learning model for survival analysis. Outside of Maths, Matthew enjoys playing futsal, watching sport, and reading philosophy.

### Allen Paul

Allen completed his undergraduate and integrated masters, at the University of Warwick in 2020. Throughout his undergraduate and integrated masters, he has enjoyed working with topics in PDE, inverse problems and machine learning. His Master's project was spent working on applications of deep learning and optimal transport to inverse problems. In his spare time, Allen enjoys watching and playing football, cooking and reading.

### Timothy Peters

Timothy finished his Joint Honours degree in Applied Maths and Physics in 2020. During his time at University College Cork he gained an interest in dynamical systems and bifurcation theory. For his final year project, he examined the quantum dot and class A laser equations and how the phenomenon of the Canard explosions was introduced when considering thermal effects. In his spare time, he enjoys reading, playing the piano, board games - the entire spectrum - and ultimate frisbee.

### Jenny Power

Jenny graduated from the University of Limerick, Ireland, in 2020, with a Bachelor's degree in Mathematics and Physics. During her studies, Jenny discovered an interest for inverse problems, waves, and geometrical optics. 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. He is looking forward to exploring the topics of both machine learning and data assimilation. Other than maths, Seb also enjoys hiking, watching horror movies, and practicing karate.
