About me
My research has centred around singularity theory and its application in mathematical robotics, where there is a wide range of problems involving interesting geometry. Relevant language and tools come from algebraic geometry, especially the theory of invariants and Gröbner bases, differential geometry and Lie groups. I have taught graduate courses in all these topics and they feature in my published research.
From 2001-04 and 2013-18, I was head of school. During those terms, I aimed to ensure students have the best possible education in the mathematical sciences, whether they enjoy the theoretical and abstract aspects or understanding how they can be used to solve problems in so many other fields. Both of these make mathematics and statistics students among the most sought after graduates in employment. I have worked with colleagues on the development of new programmes in actuarial science, applied statistics and data science, and developed close links with engineering and computer science as well as strong connections with schools and secondary teachers. The mathematical sciences have also maintained and grown a fine reputation as one of the university’s leading research centres, attracting funding both in New Zealand and internationally.
Interests
I am currently working on problems in singularities in parallel robot kinematics, invariant theory and the classification of mechanisms, and pseudoinverses for non-Riemannian metrics and their application. Loveday Kempthorne’s PhD thesis on mathematics and poetry, including the Romanian mathematician/poet Dan Barbilian/Ion Barbu, has sparked a separate avenue of research interest.
Supervision interest
I will supervise postgraduate projects in singularity theory, especially with application to kinematics, and other aspects of the geometry of motion using techniques of algebraic geometry and Lie theory.
