Abstract: The first detections of gravitational waves by Advanced LIGO and Virgo seems imminent and will open up a new observational window to the Universe. Inaugurating GW astronomy requires extension of this existing network to a global network including LIGO-India to provide good sky localization for the GW sources. LIGO-India will thus play a key role in locating and deciphering these sources with subsequent implications for astrophysics, cosmology and fundamental physics. The status of LIGO-India project and importantly its research interfaces with basic science, high end technology and computation will be finally indicated.
