I will review some of the recent exciting progress in our knowledge of graphene, a remarkable monolayer allotrope of carbon which promises to have important technological applications, with particular focus on its electronic properties. Next I will introduce an effective 2+1d relativistic field theory description, taking account of inter-electron interactions, and argue that the low-energy behaviour of the charge carriers may be described by a quantum critical point. I will present results of numerical Monte Carlo simulations to show that the QCP may be relevant for physical graphene.
