The Atlas3D Survey comprises spatially-resolved spectroscopic data for a complete, volume-limited sample of 260 early-type galaxies observed within the local 40 Mpc volume. This K-band selected sample spans a range in mass from 10e10 to 10e12 solar masses, and probes two orders of magnitude in local galaxy density, giving a large range in mass and environment. Our integral-field spectroscopy covers on average more than one effective radius, providing a complete picture of most of the stellar content of these objects. I will present recent results analysing the global star formation histories of these objects as a function of mass and environment, and explore evidence for a systematically varying IMF normalisation as derived from a combined dynamics and stellar population approach.
