Stellar Populations at Higher Redshifts

We will review some recent advances in understanding the evolution of stellar populations in galaxies at relatively higher redshifts (z ≳ 0.5). We will focus on "mass assembly", "down-sizing" and "high-z zoo" which have been among the most major topics and have seen great observational achievements in the past few years. In particular, wide-field near-infrared surveys, large spectroscopic surveys, and the Spitzer observations at infrared wavelengths, have unveiled underlying stellar masses and dusty star formation in high-z galaxies, which have been crucial in making such recent progresses.
