The word geometry means measurement of the
earth. We will consider systems of geometry for measuring an
idealised conception of the earth (Euclidean) the actual earth (spherical)
and a possibility for measuring the universe (hyperbolic). This
course will take a more personal philosophical perspective on geometry
rather than a computational or result-based perspective. In this
class we will use several different methods to analyse

Areas of research
- Low-dimensional Topology
- Knots, Links, and 3-manifolds
I am currently pursuing several research projects. The newest of the
projects is an exploration of the role of Euclid's Fourth Postulate:
"All right angles are equal." The older of these projects
consists of investigating how the Casson-Walker-Lescop 3-manifold
invariant changes when modifying the presenting link for a 3-manifold.
This project has evolved into studying questions of the Ohtsuki invariants
of rational homology spheres, and questions of the space of finite type
invariants for links of three or more components. Another long-term
project is to study symmetries of links. In particular I am
examining a refinement of unlinking number accounting for which components
are involved in each of the crossing changes, a so-called coloured
unlinking number. Finally, I am examining comparisons and connections
between mathematician Evariste Galois and composer Hector Berlioz.
