Ergodic Theory and Dynamical Systems
(See also Robert MacKay, James Robinson, and David Wood)
Adam Epstein offers projects in Complex and Arithmetic Dynamical Systems, for example:
Arithmetic Questions in Holomorphic Dynamics: Consider the polynomials F_n(c) = p_c o ... o p_c(0) (nfold selfcomposition) where p_c(z) = z^2 + c. It is known that all roots of F_n(c) are simple. The polynomial F_n splits into factors, some of which arise as F_m for smaller m dividing n: when such factors are divided out, the resulting polynomials are conjectured to be irreducible. Questions of this nature arise for other interesting families of rational maps, and little is known in general. Wellorganised computer experimentation would be a good start. This would be an appropriate project for a student who has taken, or will be taking Algebraic Number Theory (or Galois Theory). Familiarity with basics from Complex Analysis and Dynamical Systems would also be useful.

Fluid Dynamics
(See also Dwight Barkley, Tobias Grafke and the Applied Analysis and Computational Mathematics sections above)
Thomasina Ball is interested in mathematical modelling of fluid dynamical phenomena motivated by observations of the natural world. The applications predominantly originate from geophysical flows at both large and smallscales but can also have significant relevance to many flows found in industrial processes. Specific topics include gravitydriven flows, nonNewtonian rheologies, HeleShaw flows, instabilities (SaffmanTaylor instability, fracture instability of soft gels, buckling instabilities due to rheology contrasts). Projects are likely to include a range of theoretical and computational modelling of PDEs. An interest in modules such as MA3D1 Fluid Dynamics and MA4L0 Advanced Topics in Fluids is useful.
Radu Cimpeanu supervises projects at the intersection between mathematical modelling, asymptotic analysis, solutions for ordinary/partial differential equations and high performance computing (including computational linear algebra and large scale system solvers). Specific topics in fluid mechanics include interfacial flows (modelling, analysis, simulation and applications of drops, bubbles and liquid films), rheological flows (from chocolate to deicing fluids) and novel mathematical models for the cultivated meat industry. Some projects are likely to include multiphysics aspects such as acoustics, heat transfer and electromagnetism. From a mathematical standpoint, there are exciting opportunities to combine classical (continuum) modelling with discrete and data scientific streams, as well as integrating approaches such as control theory or hybrid modelling into areas previously unexplored with such tools. More generally, work on any of the above will likely involve a mixture of analytical and computational techniques (which can be tailored depending on your own interests and what skillset you wish to develop), as well as the interplay between them.
Shreyas Mandre's research topics are based on application of PDEs (generally arising from continuum considerations) to mathematical modelling of realworld problems. The applications usually arise from curiosity about the natural world and range from biomechanics (e.g. human foot, fish fins and embryos, bird flight and fish swimming) to interfacial fluid mechanics (e.g. surfactant boats, soap films and bubbles), environment (e.g. life of submerged vegetation). More recently, I have been dabbling in understanding how natural selection leads to form and function in biology. If you have a curiousitydriven mathematical modelling problem that you wish to investigate, I welcome them. For inquiring about specific projects, I encourage students to get in touch over email with a brief background and expression of the topic that most interests them. Having taken MA3D1: Fluid Dynamics is an additional advantage. For more information, see my website.
James Sprittles offers projects on the mathematical modelling and computational simulation of fluid mechanical phenomena, particularly those driven by complex interfacial effects which are prevalent in the emerging field of micro/nanofluidics. These microflows often require new modelling approaches, involving both continuum and particlebased methods, coupled to efficient computational techniques and are currently an area of intensive research interest. Possible projects include (but are not limited to):
Gas Dynamics in FreeSurface Flows: Thin films of gas often have a huge influence on the dynamics of liquid volumes, e.g. when drops impact solids, but at present are lacking an accurate theoretical description (in fact, often their influence is ignored). The problem is that their dimension is such that classical continuum mechanics fails and kinetic theory governed by the Boltzmann equation is required. This project will involve developing new models for this class of flows, with particular attention applied to the coupling of kinetic theory with continuum mechanics, and exploiting scaleseparation to make these models computationally tractable.
Mathematical Modelling of 3D Printing: This project will focus on the creation of ‘printed electronics’, where metallic nanoparticles are suspended within a liquid microdrop, deposited upon a (also printed) polymer substrate and then form (e.g.) conductive tracks when the liquid evaporates. This project will develop a mathematical model that captures the drop dynamics and offers unique insight and understanding that cannot be obtained from experiments alone. Classical applied mathematics techniques will be deployed to provide simple analyses alongside more direct computational approaches.

Mathematical Biology, Epidemiology, Ecology and Evolution
(see also Charles Elliott, Shreyas Mandre and Björn Stinner)
Nigel Burroughs applies mathematical and statistical methods to biological systems. He is primarily interested in understanding the mechanics and mechanisms of cells, in effect how they work and achieve the spectacular range of behaviours that are observed. He uses a combination of model development, mathematical analysis (eg dynamical systems methods), simulation and statistical computation (Markov chain Monte Carlo methods), with both deterministic and stochastic models. The projects below should give you some idea of what projects I can suggest, but these are not definitive. 1,2 examine the mechanics of cell division, from the duplication and separation of the chromosomes to the mechanical separation of cells into two daughter cells, 3,4 are on microtubule modelling and 5 is on cancer modelling.
1. Modelling chromosome dynamics. Chromosomes are duplicated but then have to be divided so that each daughter cell gets one and only one copy. This is achieved by 'holding' the pairs at the cell equator until all pairs are in position. Mathematically we can think of this system as two particles in a 1D box connected by a spring and pushed/pulled separately from the ends. The surprising observation is that chromosomes oscillate from side to side across the cell equator. How this occurs is poorly understood, but this is believed to involve a tension sensor that effectively acts as a means of communication between the two chromosomes. This project would involve analysis of deterministic and stochastic models of oscillation of paired chromosomes (dynamical systems techniques and simulation), examining different mechanisms of feedback/communication that give rise to oscillations. Deterministic models are nonsmooth dynamical systems, whilst stochastic models are based on the OrnsteinUhlenbeck process (or more generally switching diffusions).
2. Statistical computation (Markov chain Monte Carlo, MCMC) analysis of chromosome oscillations. See above (1) for system description. Here you would use our large database of chromosome trajectories (1000s of trajectories) to understand the statistical structure of chromosome oscillations, fitting sawtooth like oscillatory profiles. Experience with/exposure to MCMC, hidden Markov chains and probability theory is essential.
3. Modelling microtubule bending. Microtubules are biological polymers that polymerise into tubes and exhibit elastic bending properties. Here you will examine models and simulations of microtubule bending in fluid flow and binding of proteins that enhance the curvature.
4. Reverse engineering microtubules. Microtubules are biological polymers; they polymerise into tubes and exhibit what is called dynamical instability, switching from periods of growth to decay. What causes this (stochastic) switching is unknown but likely an emergent property of the microtubule lattice. The idea of this project would be to construct models and an MCMC algorithm to fit those models of lattice dynamics to data to examine the degree to which such data can inform on the underlying processes. Experience with MCMC and probability theory is essential.
5. Cancer dynamics. What is the optimal cancer therapy for a given cancer? By using mathematical models of tumours and drug activity, control theory can be used to optimise the therapy  for instance both dose scheduling and combinations of drugs. Fundamental to this is what should be optimised, in a mathematical framework what objective function should be used. This project would involve examining various growth models of tumours and normal tissue. Both deterministic (ODEs, PDEs) and stochastic (branching processes, stochastic logistic model) can be looked at.
Prospective students should contact him to discuss further details. [Experience with MCMC means acquaintance with Gibbs and MetropolisHastings algorithms and their use in simulating posterior probability distributions. Experience coding an algorithm for a simple problem would be an advantage].
Emma Davis uses mathematical models to investigate the emergence and spread of infectious diseases through human populations, with a particular focus on tropical diseases that affect populations with poor healthcare access. Mathematical techniques could feed into a project include stochastic / branching processes, systems of differential equations, statistical analysis and computer simulations. Students would benefit from taking "MA4E7: Population Dynamics" and/or "MA4M1: Epidemiology by Example" either before or during the project, due to a substantial overlap in methodology and theory. Example ideas for projects include: 1. Developing a metapopulation model (representing interacting populations) to investigate the impact of crossborder migration on neglected tropical disease transmission in scenarios where neighbouring areas or countries may have contrasting public health strategies or resources. 2. Investigating how assumptions around clustering (or 'superspreading') of SARSCoV2 transmission can impact model forecasts. 3. Using a model of SARSCoV2 lateral flow test positivity over time since exposure to derive transmission networks by determining the likely direction of transmission between positive contacts.
Louise Dyson works on mathematical modelling of biological systems, especially the epidemiology of neglected tropical diseases and the analysis of biological systems in which noise plays an important role.
Ed Hill is a mathematical epidemiologist and infectious disease modeller. I like to offer projects in public and veterinary health policy, zoonoses and interdisciplinary problems in epidemiology that involve the dynamics of behaviour. Approaches involve the application of mathematical and computational methods, including the development of models, parameter inference and the evaluation of interventions via computational simulation. Students wishing to undertake a project in these topics would benefit from taking "MA4E7: Population Dynamics" and/or "MA4M1: Epidemiology by Example" either before or during the project. A list of example projects may be found hereLink opens in a new window.
Matt Keeling offers projects in the areas of Epidemiology,Ecology or Evolution. Epidemiology (the study of infectious diseases and their spread in populations), Ecology (the study of animal/plant populations and their environment), Epidemiology (the study of disease spread and control) and Evolution (the study of the longterm dynamics of populations) present a wide variety of interesting problems that require a mathematical approach. There are a vast number of problems and approaches that could be studied, ranging from modeldevelopment, to computer simulation, to statistical analysis. If you've attended (or planning to attend) MA4E7: Population Dynamics, that would be a distinct advantage although not essential. I like to offer projects that show how the mathematical techniques you've learnt can be applied to real questions to obtain useful or meaningful insights. If you're interest, its probably easiest to come and talk with me, and together we can determine a specific project that matches your interests and skills.
Recent projects have included the evolution and competition of influenza strains, diffusion approximations to disease spread on networks, optimal control of spatial epidemics, NicholsonBailey lattice models.
David Rand. His main research interest is Systems Biology, particularly understanding the design principles of regulatory and signalling systems in cells. Prospective students would have to contact him to discuss further details.
Kat Rock is a mathematical epidemiologist interested in populationlevel disease dynamics. In particular her focus is on transmission of vectorborne (insecttransmitted) infections, infections in low or middleincome countries, and bringing together dynamic transmission modelling and health economic evaluation. She teaches the MA4M1 “Epidemiology by Example” course and it would be recommended to have taken this and/or “Population Dynamics” (MA4E7) already or alongside an Rproject.
Robin Thompson develops mathematical models of infectious disease outbreaks and uses them to guide control measures. This includes developing stochastic models, parameterising them by applying statistical inference techniques, and then using them to test out different possible interventions. Recent research projects have involved the use of stochastic models early in outbreaks (to estimate the risk that initial cases will lead to a major epidemic as opposed to fading out as a minor outbreak) and late in outbreaks (to determine when outbreaks have finished so that control measures can be removed).
Mike Tildesley works on the development of mathematical models to simulate the spread of livestock and zoonotic diseases.
Dave Wood would be willing to discuss possible topics given the information below. His main interests for projects include ecological type modelling, investigating systems with symmetry (including but not limited to applications to arthropod locomotion) and applications of mathematics in industry. Systems with symmetry could be theoretical or applied, but would concentrate on using methods from MA3J3 Bifurcations, Catastrophes and Symmetry, so this may interest students who have taken that. The industrial applications could cover a broad range of mathematical disciplines and be a survey of some problems that have already been studied or a look at a new problem involving original research. Ecological modelling I would be happy to consider any suitable application that a student feels passionate about (see below for a couple of past such projects).
Previous titles he has supervised include: “Coupled cell networks, bifurcations and symmetry”, “The effects of tuna fishing on dolphin populations”, “Symmetry in coupled cells and neuronal networks”, “Applications of maths in industry”, “Discrete maths in industry”, “Modelling the Future of the Hawaiian Honeycreeper: An Ecological and Epidemiological problem” (the latter of which led to a successful PhD).

Number theory
(See also Adam Epstein, Joel Moreira)
Sam Chow supervises projects in analytic number theory, diophantine equations, and diophantine approximation.
Adam Harper is interested in analytic and probabilistic number theory, and would be willing to supervise projects in these areas. The basic goal is to use methods of analysis (real, complex, Fourier, probability) to understand the distribution of number theoretic objects, like prime numbers. A project would likely involve working through a couple of papers from the (fairly) recent research literature, and trying to understand and synthesise them.
PakHin Lee is primarily interested in algebraic number theory, particularly topics concerning modular forms, elliptic curves and Iwasawa theory. He can also supervise projects related to the Langlands program, such as automorphic forms, Eisenstein series and Lfunctions; these are suitable, but not limited, to students with a strong background in analysis.

He is also interested in topology and mathematical physics, especially the foundational aspects of quantum field theory. He is willing to supervise a project in any combination of these areas.
Simon Myerson offers projects in analytic number theory and harmonic analysis. The fourth year course called "analytic number theory" is actually about one rather special part of analytic number theory and not very relevant to what I usually do. An interest in number theory and analysis is a must. There are applications to PDEs which would interest students talking MA4J0, although they are unlikely to be the focus of the project. Projects close to algebraic number theory would also be possible if you have an idea in mind.
 Samir Siksek is interested in number theory and diophantine equations. Prospective students would have to contact him to discuss further details.

(see also Josephine Evans, Adam Harper, Ian Melbourne, Oleg Zaboronski, as well as the Complexity Science and Mathematical Physics)
Tobias Grafke is interested in numerical methods and mathematical tools to analyse stochastic systems. Applications include fluid dynamics and turbulence, atmosphere and ocean dynamics, and biological and chemical systems.
Tim Sullivan offers projects in uncertainty quantification and inverse problems, understood as the meeting point of numerical analysis, applied probability and statistics, and scientific computation. He also has interests in data science and machine learning.
 INTEGRABLE PROBABILITY : this is a rather new area within probability which explores remarkable connections between probability and algebraic structures (representation theory, algebraic combinatorics etc). A motivation for this development has been the understanding of the so called KardarParisiZhang universality, which governs fluctuations of stochastic growth model (colonies of bacteria, spread of fluid in porous media etc). Remarkably, these fluctuation are not governed by the standard central limit theorem but rather from distributions related to random matrix theory. Some favour on this topic is provided by these notes
https://arxiv.org/pdf/1812.07204.pdf
https://warwick.ac.uk/fac/sci/statistics/staff/academicresearch/zygouras/florence.pdf  SCALING LIMITS OF DISORDERED SYSTEMS AND SPDEs: Stochastic PDEs (SPDEs) have been proposed as continuum scaling limits of statistical mechanics models. However, both the well posedness of the SPDEs and the convergence of the discrete models to these are very challenging problems. The first problem has been recently largely settled below the socalled "critical dimension”) through the theory of Regularity Structures (by Hairer) or Paracontrollled Districutions (by GubinelliImkellePerkowski). At the critical dimension things are much more challenging. This project can spin around the above theories, some exploration of critical dimensional statistical mechanics and/or scaling limits. Some flavour of the topic can be obtained in these notes

Title: Metastability and large deviations for system of SDE's.
Description: An interesting phenomenon has been observed recently for systems of differential equations inspired by hydrodynamics: the addition of noise to a system of ODE's with a single fixed point leads to the emergence of multiple (quasi) fixed points. The aim of the project is to study classes of such ODE's and possibly apply the findings to the study of metastability in turbulence.
Key words and phrases: metastability; stochastic differential equations; time scale separation; large deviations; WentzellFreidlin theory; instanton trajectory; Fredholm determinants; Szego's theorems
Title: Matrix valued Brownian motions
Description: Random matrix theory is a multidisciplinary subject possessing an intrinsic mathematical beauty and having applications to a range of applied scinces from string theory to data science and statistics. A dynamical version of random matrix theory is matrix valued Brownian motion. For the Hermitian matrices this gives rise to such a classical stochastic process as Dyson Brownian motion. The aim of the project is to study random matrix evolution for the nonHermitian case.
Key words and phrases: matrixvalued Brownian motion; Berezin caclulus; supersymmetry; determinant; pfaffian; stochastic differential equations; point processes
Title: Markov dualities and interacting particle systems in one dimension
Description: More often than not, Markov interacting particle systems in one dimensions exhibit strong fluctuations which render their approximate description using differential equations ('mean field theory') useless. One of the methods of analysing such systems is based on Markov duality which allows to extract at least partial information about the system from its dual. But how do you find these dualities? The aim of the project is to learn about Markov dualities and investigate the dualities for certain classes of strongly fluctuating interacting particle systems.
Key words and phrases: Markov processes in continuous time, interacting particle systems, Markov duality; Hecke algebras; YangBaxter equation; Rmatrix; determinatal point processes; pfaffian point processes
Title: Moment factorisation for the stochastic heat equation.
Description: It has been discovered recently, that the exponential moments of the solution to the stochastic partial differential heat equation satisfy classical integrable PDE's such as KadomtsevPetviashvili equations. The discovery came from the analysis of exact formulae for the exponential moments available for certain initial conditions. One of the consequences is that certain moments for the stochastic heat equations must factor into the linear combinations of products of the lower order moments. The aim of the project is to investigate the factorisation phenomenon from the point of view of stochastic analysis studying the solutions to the stochastic heat equation itself.
Keywords: Stochastic heat equation: stochastic processes, Ito's calculus; KPZ equation; KP integrable hierarchy; Fredholm determinants; intermittency; moment problem
