Abstract: Star formation takes place mostly in star-forming galaxies (SFGs) from high-z to the present day. The tight correlation between star formation rates (SFRs) and stellar mass among SFGs, namely the so-called main sequence of SFGs, has become one of the fundamental relationships to verify models of galaxy formation and evolution. Characterizing the slope, normalization and scatter of the main sequence provides key insights into the physical processes regulating star formation in galaxies. I will present recent observational advances in measuring features of the main sequence of SFGs across cosmic time, and discuss implications for understanding bursty star formation histories of low- and high-mass SFGs, relative roles of in situ star formation versus mergers in driving galaxy mass assembly, and effects of bulge growth on galaxy star formation.
