Research
I am a member of the Board of Scrutiny. My manifesto is simple. I believe Universities should be self-governing communities. They have become administrative oligarchies. It is important to hold the executive to account. If you wish to raise an issue for the Board, please contact me by email
Please see my personal homepage for press releases & campaigns. My writing for 'The Times Higher Educational Supplement' is under the Section 'Science & Society' below. Thie following description of my research interests is more technical & research-oriented.
Galactic structure and dynamics. The bar, disk and halo of the Milky Way galaxy. The M31 galaxy and the Local Group.
The dark matter problem and astroparticle physics. Extremely dark matter dominated objects such as the dwarf spheroidal and dwarf irregular galaxies of the Local Group.
Survey science, the Sloan Digital sky survey, the GAIA satellite, transient astronomy, science alerts.
Theoretical galaxy models, self-consistent solutions of the Boltzmann equation. Galactic stability and spiral structure.
Gravitational lensing and microlensing. The mathematical structure of lensing.
Solar system dynamics, extra-solar planets, numerical integration methods.
Non-linear science, integrability and chaos. Super-integrability.
Astroparticle physics. Ultra-high energy cosmic rays.
