Abstract: Fifty years ago Blaine Lawson constructed the first examples, beyond geodesic spheres and Clifford tori, of closed minimal surfaces embedded in the round 3-sphere. I will review some natural questions (and a few answers) concerning the space of such surfaces, with a focus on results recently obtained for the Lawsons in collaboration with Nicos Kapouleas: namely a characterization by their topology and symmetries and, for an infinite subfamily, the computation of their Morse index and nullity.
