Some applications of effective field theory in hadron physics

I will present some applications of effective field theory in hadron structure and spectrum. Finite range regularization will be discussed in the extrapolation of lattice data on magnetic form factors, strange form factors, charge radii, first moments, etc. The unitary chiral perturbation theory is applied to study the open charm and hidden charm states. The recent work on the asymmetry of sea quark parton distribution function in proton will also be discussed.
