### Tom Davis

Tom graduated from the University of Oxford in 2015 with a BA in Economics and Management, and completed an MSc in Financial Engineering at the University of Birmingham in 2018. He spent the intervening years working for an insurance company as an actuarial trainee, which is where Tom really began to find his passion for applied maths generally, and probability theory in particular. Since then, he has also developed an interest in numerical analysis. As part of his MSc, Tom completed a project in which he implemented and benchmarked, using C++, a Monte Carlo-based method for calculating guaranteed confidence intervals for means of random variables. In his spare time, Tom enjoys reading and programming, and is also (slowly) learning how to cook.

Following her undergraduate degree, she co-tutored two engineering dissertations and worked as a research assistant at the Centre for Research in Mathematics in Paraguay, where she took part in a research project in collaboration with colleagues in the Nephrology Department of the Clinics Hospital at UNA. Her other interests are reading, watching films, swimming and learning Korean and Finnish.

### Eileen Russell

Eileen graduated from the University of Limerick with a BSc in Mathematics and Physics in 2018. Her final year project involved applying asymptotic techniques to non-linear ordinary differential equations in order to model a fluid dynamics problem. Eileen enjoys mathematical modelling and applied mathematics. During her degree, she completed a placement with Philips Healthcare in the Netherlands. Following her Bachelor’s degree, she completed a research internship at the University of Limerick, which involved Markov Chains. Outside of Maths, Eileen enjoys playing camogie and Gaelic football.

### Zsófia Talyigas

Zsófia graduated from Budapest in 2018 with an MSc in mathematics, with special interest in probability and stochastics. As part of her Master's studies she spent five months in Stockholm with the Erasmus+ program. In her Master's thesis she worked out the proofs of two limit theorems about directed random polymer models. She also took part in two internships during her Master's years, exploring a Markov model for reliability problems of telecommunications services and also financial models. Apart from math she likes to travel and to do sport, especially table tennis or tennis.

### Jordan Taylor

Jordan graduated from the University of East Anglia in 2015 with a BSc in Actuarial Sciences. He then worked as an analyst for NHS Property Services Ltd in London for 2 years where he mainly created, developed, and trained staff from various departments on financial models. He noticed the increasing uses of machine learning and artificial intelligence in a wide range of applications and went on to complete his MSc in Data Science at the University of Bath. His Master's dissertation was on the applications of machine learning for stock investment, whereby given some state representation of the market, one had to decide whether to buy or sell a stock. Jordan modelled this as a reinforcement learning problem with the use of neural networks as a function approximator. In his spare time, Jordan enjoys playing table tennis, badminton and the piano.

### Jason Wood

Jason graduated from the University of York in 2018 with an MMath degree in mathematics and physics. His Master’s thesis explored how individual fluid particles were moved by the motion of a swimming microorganism. He is currently interested in exploring epidemiology and the more general field of mathematical biology. Jason enjoys board games and literature, as well as the niche sport of underwater hockey.

### Josh Young

Josh graduated from the University of Bath in 2018 with an MMath, where he focused primarily on Probability Theory. He completed two summer projects with the Bath Institute for Mathematical Innovation, firstly on the Keston-Stigum theorem for discrete time branching processes, and secondly on the optimization of tensegrity structures. His final year project was on the conformal invariance of critical site percolation but he is interested in learning more about a wide variety of topics. Besides maths, Josh enjoys reading, films, squash, and knitting bad hats.

# SAMBa 2018 Aligned Students

Aligned students work on PhD projects generated by SAMBa, or work in close collaboration with the cohort. They are often co-funded by our partners.

### Eric Baruch Gutiérrez Castillo

Eric obtained his Master's degree in Applied Mathematics in 2016 from Delft University of Technology in the Netherlands. While there he did an internship in Deltares, a research institute dedicated to water and subsoil research, where he collaborated in the project "Tracking Plastic in the Ocean" for five months, which involved the modelling of global ocean currents for the prediction of plastic waste accumulation in the ocean surface. For the past two years he has worked as a researcher for the Mexican Institute of Oil, in Mexico City, where he has mostly focused in numerical analysis for different geophysical models. The most recent of these projects has been an effort to model low frequency acoustic waves in saturated elastic porous media, for oil reservoir simulation. He speaks four languages, has a passion for books and movies, and enjoys wall climbing, football and capoeira.

### Yvonne Krumbeck

Working on randomness in biological populations, funded by The Royal Society (Supervisors: Tim Rogers and George Constable)

In 2015, Yvonne completed a BSc in Physics at the University of Münster. Fascinated by non-linear dynamics, she entered the Master's programme in Complex Adaptive Systems at the University of Gothenburg and graduated in 2018. She developed a special interest in life science and wants to apply her maths and programming skills in an interdisciplinary environment. Thus, she devotes herself to the field of mathematical biology and currently works on population dynamics involving more than two mating types and probabilistic fitness distributions. Besides research, she likes learning new languages and enjoys outdoor activities, such as hiking, bird watching and photography, or cosy film and boardgame evenings.
