In his spare time, Stefano enjoys hiking, indoor climbing and listening to music.

### Teo Deveney

Teo completed a mathematics BSc at Bath in 2016 and an MSc in mathematical modelling and scientific computing at Oxford in 2017 - specialising in probability, statistics, and numerical analysis throughout. His Master’s thesis analysed the behaviour of ODEs driven by smooth noise functions; and he also spent a summer researching a numerical approach to solving an optimal stopping problem on a measure valued stochastic process. He remains interested in many areas of SAMBa and is excited to build deeper knowledge in a breadth of topics before choosing a direction to specialise. His hobbies include basketball, music, exercise, and film.

Following her undergraduate, Shaunagh undertook an industrial research placement at the Institute for Pure and Applied Mathematics in Los Angeles, collaborating with a National Research Laboratory. Shaunagh continued her studies at the University of Bath, completing an MSc in Modern Applications of Mathematics. Her Master’s dissertation was based on corner flows of viscoelastic fluids, in particular looking at the stress singularities around sharp re-entrant corners. Outside of maths, Shaunagh has a black belt in karate, and also enjoys watching Gaelic football, and reading.

### Tom Finn

Tom graduated from Bath in 2017 with an MMath and is particularly interested in analysis and probability. He completed a summer project on the mixing times of load balancing schemes and his final year project used the close relationship between random walks, martingales, and harmonic functions to explicitly find the potential kernel for the simple random walk on the hexagonal lattice. Apart from Maths, Tom's favourite things include cricket, handball, obscure Simpsons’ references, and films by Paul Thomas Anderson.

### Christoph Gartner

Christoph graduated from the Karlsruher Institute for Technology in 2017 with an MSc degree and did his final project on transport of random measures and Brownian excursion theory. His research interests are Lévy processes, random walks, and stochastic calculus just to name a few. Outside of working and mathematics he enjoys travelling, running, reading, cycling and learning languages.

### Will Graham

Will graduated from the University of Bath with an MSci in Maths and Physics; where his Master’s project was concerned with using techniques from statistical mechanics to model fluid systems at criticality. Thanks to the physics portion of his undergrad, his interests are largely in modelling and applied maths, however he also maintains a quiet interest in analysis. When not filling his head with maths, Will enjoys card- and board games.

### Paolo Grazieschi

Paolo graduated in 2017 at the Università di Pisa (with a thesis on stochastic models for the human brain. He has then moved to the University of Warwick where he was a member of the MASDOC CDT programme. After completing the first year with an MSc, he moved to Bath to pursue his PhD. His work concentrates on stochastic particle system models and their convergence to stochastic partial differential equations; particularly, he is very interested in questions of regularity and well-posedness for SPDEs as well as the way the limit equations arises from the particle system. Outside of mathematics, Paolo loves running and cycling, regularly taking part in athletics competitions. He is also often in search for good food and he likes cinemas and theatres.

### Trishen Gunaratnam

Trishen graduated in 2017 with an MMath from the University of Warwick. He completed the MSc year of the MASDOC CDT programme there but has transferred to the University of Bath to pursue his PhD. His MSc dissertation made progress towards: i) establishing quasi-invariance of Gaussian measures for the cubic nonlinear wave equation in 3d; and ii) establishing a decay of spectral gap for stochastic quantisation equations of low temperature $\Phi^{4$-theories} in 2d. 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.

### Yyanis Johnson-Llambias

Yyanis graduated from the University of Oxford in 2017 with an MMath in Mathematics, with a broad interest in applications. He has undertaken summer projects on topics in fluid dynamics at Oxford and Perm Krai, Russia, and has written undergraduate and Master’s theses on the topics of Thermohaline circulation oceanography and the Stokes wave. Outside of mathematics, Yyanis enjoys sports (occasionally seriously but mainly frivolously), films, and music.

### Kevin Olding

Kevin graduated with an MMath degree in Mathematics from the University of Oxford in 2007 and then completed the Graduate Diploma in Law and the Legal Practice Course. He worked for a year in a law firm and then returned to Mathematics to teach in two secondary schools in London. Whilst teaching he studied part time for an MSc in Applied Statistics and Stochastic Modelling at Birkbeck College, London and subsequently taught there. Returning to full time study at SAMBa he continues to teach Mathematics through his Mathsaurus YouTube channel.
