My research is centred on understanding of the complex processes of galaxy formation and evolution using multi-wavelength data. Current research projects include: physical properties of z>3-6 starburst galaxies (Lyman-break galaxies); low-metallicity starbursts as analogues to high-z LBGs; the starburst-AGN connection in and properties of infrared and sub-mm luminous galaxies; dynamics of z~1 hyper-luminous infrared galaxies and z~2-3 star-forming galaxies; kinematics of powerful z~1 radio galaxies; discovery & follow-up of gravitational lenses selected in the optical and the sub-mm. I am co-founder of the citizen science project to find gravitational lenses Space Warps
