Jet substructure modifications in heavy ion collisions contain useful information about the quark-gluon plasma. The precise understanding of jet substructures therefore becomes the key to extracting the medium properties. I will discuss the advantage of using effective field theory techniques to systematically perform precise jet substructure calculations. While jet shapes and jet fragmentation functions are covered in this workshop, I will focus on discussing a qualitatively different observable, the jet mass. It is sensitive to soft radiation which allows us to probe the physics at the medium scale in more details. I will explain the factorization and resummation framework, and the challenge in performing precise calculation of jet mass in heavy ion collisions.
