Concepts for future detectors

What incremental improvements can we make to improve the sensitivity of LIGO? I led the development of the LIGO-LF concept which aims to improve LIGO's sensitivity in the 5-30 Hz band without sacrificing its high-frequency performance.

I am also interested in developing concepts for future gravitational-wave detectors. One example is TianGO, a decihertz detector that bridges the gap between LISA and LIGO. Cool science TianGO can deliver includes dark-siren cosmology and early warning of binary neutron stars.
