The dynamical modelling technique is one of the major methods to measure the dark matter distribution in galaxies. Due to the degeneracy of baryonic and dark matter and the limitation of extended tracers in galaxies, accurate measurements of dark matter distribution in large sample of galaxies are still inadequate. We introduce our method to constrain the dark matter distribution in galaxies with dynamical models which combine stellar IFU and spatially resolved neutral hydrogen (HI) velocity field, and apply this method to a small sample of intermediate-mass early-type galaxies. We also develop a method which combines stellar IFU integrated HI spectra, and apply this method to a representative sample of nearby galaxies. This research is important to constrain the baryonic feedback theories in cosmological models of cold dark matter, and will improve our understanding of the co-evolution process of baryonic and dark matter in galaxies.
