The Legacy ExtraGalactic UV Survey (LEGUS) is a HST Cycle 21 Treasury program. We aim at the investigation of recent (<~50 Myr) star formation and its relation with galactic environment in 50 nearby galaxies within the local 12 Mpc. Five-band imaging from the near-ultraviolet to the I-band will allow us to study accurate recent star formation histories from resolved massive stars, and the extinction-corrected ages and masses of star clusters and associations. I will present (1) the overview and the current status of LEGUS, (2) my previous work with the HST Early Release Science data, and (3) my research plan using IGRINS.
