      At Multiverse we're building an outstanding alternative to university through in-work, applied training. I work with data analyst apprentices, teaching them the concepts, software packages, statistics, and technical skills to help them draw insights from data and communicate these insights. More importantly, I then help them apply these skills in their work to get real benefit from what they're learning.

      My research is on the intersection of noncommutative algebra, category theory, geometry, and model theory. Classical algebraic geometry is based on a construction called the Zariski spectrum of a commutative ring. There is an alternative to this construction, called the injective spectrum, and first considered by P. Gabriel. I study injective spectra of noncommutative rings and the extent to which results from the classical, commutative case generalise to this context. To do this, I use ideas… Show more My research is on the intersection of noncommutative algebra, category theory, geometry, and model theory. Classical algebraic geometry is based on a construction called the Zariski spectrum of a commutative ring. There is an alternative to this construction, called the injective spectrum, and first considered by P. Gabriel. I study injective spectra of noncommutative rings and the extent to which results from the classical, commutative case generalise to this context. To do this, I use ideas from category theory, an abstract formalisation which underlies much of modern mathematics, and model theory, an area of logic concerned with the relationship between the syntax of formal logical expressions and the semantics of what those expressions mean in a particular context, or model. As well as performing research, I am a regular contributor at an informal seminar in my research group, giving both prepared and sometimes impromptu talks both on my research and on background topics. I have also presented to the University of Manchester Logic seminar, on model theoretic aspects of my work, and gave a talk at the International Conference on Representations of Algebras 2018, in Prague.

    • Graduate Teaching Assistant
      • Jan 2016 - May 2019

      Leading problems classes and tutorials for groups of 8-12 first year maths students, and for groups of 25-35 foundation year and first year engineering students, on a range of pure mathematical and applied topics. Also assisting lecturers in delivering problems classes and individual support to second and third year maths students, on pure maths topics. I have also been a marker on numerous exams and midterm tests.

      I exploited analogies between fluid flow in pipes and electrical circuits to model behaviour of a particular tool in a gas well as an electronic circuit in a computer simulation package, to allow easy testing of the effect of different parameters of the well on the tool's behaviour. My model allowed me to give an explanation of anomalous behaviour the tool had exhibited in real life use by showing that the compressibility of the gas (modelled as capacitance in my simulation) led to a phase… Show more I exploited analogies between fluid flow in pipes and electrical circuits to model behaviour of a particular tool in a gas well as an electronic circuit in a computer simulation package, to allow easy testing of the effect of different parameters of the well on the tool's behaviour.

      I worked on the neutral beam injectors for the ITER project; these are heating elements which accelerate protons to a high speed with an electric field and pass them through an electron cloud to neutralise them, so they can pass through the magnetic containment field into the tokamak reactor and collide with the hydrogen there to heat it up to temperatures suitable for fusion.

My project was on the temperature monitoring for the injectors' water coolant system. To allow real-time monitoring of very sudden step changes in the temperature, thermocouples were inserted directly into the coolant pipes using special inserts. As part of an attempt to cut costs, it was proposed to simply weld or clamp the thermocouples to the outside of the pipe, but it was feared that this could increase the response time for step changes. My job was to determine whether or not this idea could be made to work. I worked jointly with an engineering apprentice. I focused on the theoretical aspects, while the apprentice worked more on the practical side of things. I analysed the heat flow in the pipes to study how sensitive the thermocouples should be to step changes in each of the three configurations (inserted, welded, and clamped), while the apprentice constructed a test rig. We then performed experiments on this rig and I analysed the results and presented them to the working group. Our conclusions were that welding the thermocouple to the outside of the pipe was just as effective as using the inserts, but that clamped thermocouples had a significantly slower response, because of the heat capacity of the clamp itself.
