I have the pleasure of working with the CFHTLS, the largest deep ground-based survey in existence, along with GEMS, STAGES and COSMOS, the three largest contiguous fields ever imaged with the Hubble Space Telescope. All of these surveys are ideal for my main area of research into weak gravitational lensing .

Spectacular high resolution images of galaxies from GEMS and STAGES can be seen using The Skywalker.

The Shear TEsting Program STEP is now working on its fourth project and GREAT08. Contact me if you would like access to the internal STEP pages.

For the GREAT08 challenge I've made public KSBf90, which is my software version of the typically used Kaiser, Squires and Broadhurst shape measurement method.
