My talk consists of three parts. In the first part I will introduce the basic ideas of lightfront quantization and its advantages compared to the conventional “equal-time” quantization when applied to quantum field theory. In the second part I will illustrate how lightfront quantum field theory is employed to solve relativistic bound states through three examples: 1) physical electron in QED; 2) positronium in QED; 3) baryon in QCD. In the third part I will explain the motivation of applying lightfront quantization to chiral effective theory and then discuss a tentative roadmap of such applications.
