His research interests lie in the fields of stochastic partial differential equations, Euclidean quantum field theory and statistical physics, although he maintains a general interest in mathematical physics as a whole. Outside of math, Trishen enjoys going to restaurants, seeing live jazz and going to cinemas/theatres.

### Allen Hart

Allen completed his MSci in Mathematics and Physics at the University of Bath. During his summers he worked at l'Institut Laue-Langevin, Grenoble, France looking at the scattering patterns of neutrons diffracted through materials like benzene, graphene and ice. His university projects have been varied and include simulating critical fluids and calibrating an antenna array - but he doesn't know what area of mathematics or which application to commit to at the moment. He hopes to find a fun problem during his first year at SAMBa he can attack throughout the remainder of his PhD. Outside of mathematics, Allen has done a bit of work as a ski instructor, likes to play sports, and hang out with friends.
