I am an Astronomy researcher working at the Institute of Cosmology and Gravitation, University of Portsmouth, UK. See my offical Portsmouth listing here. I am very grateful to be the 2008 Peter and Patricia Gruber Foundation Fellow. My research focuses on statistical studies of spiral galaxy properties as a trace of galaxy evolution (especially the Tully-Fisher relation, and more recently using morphologies from Galaxy Zoo) as well as the distribution and motions of galaxies in the local universe. .

Galaxy Zoo: Red Spirals
A look at the intrinsically red spirals (as red as a normal
elliptical) found in the Galaxy Zoo project.

Galaxy Zoo: Dust in Spirals
Looking at the impact of viewing angle on the colours of Galaxy
Zoo spirals - which is interpreted as
the effects of dust extinction in the disk.

The Tully-Fisher Relation in the Near Infra-Red
A new calibration of the universal Tully-Fisher (or
luminosity--rotation speed) relation for spiral galaxies. I show the variation
of the slope and zero-point with wavelength and spiral galaxy
type. Link...
