**Teaching:**

I have experience of teaching the following topics:

- Logic,
- Foundations of Mathematics,
- Univariate calculus,
- Multivariate calculus,
- Partial differential equations,
- Real analysis,
- Complex analysis,
- Probability,
- Elementary statistics,
- History of mathematics,
- Remedial/service mathematics

**Research Interests:**

My research interests are in the field of logic, specifically proof theory and visual representations of logic.

My interests in proof theory lie in formalisation of results (using proof assistants, such as Isabelle for sequent calculi. These results include Cut admissibility and invertibility.

I am interested in the visual representations of logic, specifically using diagrammatic notations to encode logical propositions and proofs. In particular, my work is focused on providing visualisations of ontologies. [top]

I am also doing some work in mathematics in Higher Education, specifically how students interact with mathematical proof. [top]

**Brief academic biography:**

My undergraduate degree was in Mathematics and Economics from the London School of Economics. I have a Masters degree, in Mathematics and the Foundations of Computer Science, from the University of Oxford, and a PhD from the University of St Andrews, entitled “Tools and Techniques for Formalising Structural Proof Theory” (supervised by Roy Dyckhoff). From January 2010 to January 2011, I was employed on the EPSRC grant “Defining Regular Languages with Diagrams” [EP/H012311/1]. In 2011-2012, I completed the Postgraduate Certificate in Teaching and Learning in Higher Education at the University of Brighton, and am currently enrolled on the MA Education (Higher Education) course.
