The growth in number, mass, and types of galaxies seen across the cosmic time and their stellar mass build-up history are some of the key observables that guides the theory of galaxy formation and evolution and also serve as important constraints on the properties of our Universe itself.  This has been one of the most urgent topics of research in astronomy in recent decades and an important science driver for current and future astronomical facilities such as the Hubble Space Telescope (HST), James Webb Space Telescope (JWST), Herschel Space Observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), and the Large Millimeter Telescope (LMT).  While the pioneering works in this field started with the study of distant galaxies using the HST in the UV and optical light, I will discuss how new infrared and millimeter/submillimeter observations are shedding new light on this classic problem.  I will also highlight some new challenges revealed by recent observations and speculate on prospects for the future research in this area.
