Technological improvements have greatly enhanced data quality, making weak lensing, or more specifically, galaxy-galaxy lensing, a critical tool for studying galaxy evolution. Particularly, galaxy-galaxy lensing helps shed light on the physical relationship between the assembly of a galaxy and its dark matter halo, which is of paramount importance to deepen our understanding of galaxy evolution. Using the HSC and Merian surveys as examples, I will illustrate how galaxy-galaxy lensing offers a unique perspective into the galaxy-halo connection for both the most & least massive galaxies in the universe. Additionally, I'll touch upon the link between weak lensing and cosmological spectroscopic surveys, discussing their potential future applications.
