Staff Profile
Dr Stuart Hall
Lecturer
Background:
I studied at Warwick and Imperial College London and I have been working at Newcastle since 2016. I enjoy teaching a range of subjects across the disciplines represented in our school. I am part of the team that helps students make the transition from A level mathematics to university level mathematics.
Semester 1: MAS1605 Introduction to Calculus
Semester 2: MAS3713/8713 Curves and Surfaces
Semester 2: MAS1403 Quantitative Methods for Business Management
- Properties of special Riemannian metrics (Einstein metrics and Ricci solitons)
- Numerical differential geometry
Recently, I've been working with Daniel Cole and Rachael Pirie from the School of Natural and Environmental Sciences on a project that applies ideas coming from differential geometry to the problems of molecular similarity searching. Our our second preprint is available here: https://arxiv.org/abs/2301.04424
I have been thinking about the canonical Einstein metric on a complex Grassmannian. A recent preprint is available here: https://arxiv.org/abs/2403.18757.
