Gravitational waves, like light, could be gravitationally lensed by intervening matter. Recent studies suggest that we might see gravitational-wave lensing within the coming years as the current ground-based detectors are upgraded. However, the methods to detect and employ gravitational-wave lensing are entirely different from light lensing. Indeed, we detect waves instead of particles, and the source population is one of merging black holes. For these reasons, the field might also pave the way to new applications. Here I will discuss some of our recent work in the field.
