Gravitational instability (GI) is believed to be one of the main drivers of angular momentum transport in young protoplanetary discs. These discs are often massive, and the influence of their self-gravity plays a crucial role in their evolution. In this talk, I will explore the connection between protoplanetary disc kinematics and gravitational instability, highlighting how GI leaves distinct kinematic signatures. Properly interpreting these perturbations provides valuable insights into the structure and evolution of protoplanetary discs. I will present two case studies — Elias 2-27 and AB Aur — demonstrating how our kinematic models accurately capture the characteristics of these GI discs.
