Weak gravitational lensing is one of the most sensitive probes of the growth of structure in
the Universe, and is therefore a key part of the cosmological community's program for
understanding the nature of dark energy. It is also a powerful probe of the connection
between the visible components of galaxies and galaxy clusters, and the underlying dark
matter. The past few years have seen advances in weak lensing measurements with
surveys such as the Hyper Suprime-Cam (HSC) Survey, which is unique in its depth and
imaging quality compared to other ground-based weak lensing surveys. In this talk, I will
describe recent HSC survey results, along with work on weak lensing method development
aimed at resolving the challenges in this field and unlocking the scientific discovery
potential of upcoming surveys such as the Rubin Observatory Legacy Survey of Space and
Time (LSST).
