The Hopf algebra of symmetric functions has played an important role in broad areas of mathematics including representation theory. In the 1990s, Rota proposed a program to study generalizations of symmetric functions by Rota-Baxter algebras. We present the Rota program and discuss recent developments in the Rota program, including the method of renormalization. These are joint works with Jean-Yves Thibon, Houyi Yu, Bin Zhang and Jianqiang Zhao.
