HSF-India is a US National Science Foundation (NSF) funded project that began on October 1, 2022. HSF-India aims to join collaborative networks in India to networks in the U.S. and Europe in order to build the international research software collaborations required to reach the science goals of next-generation particle, nuclear and astroparticle physics experiments including the High-Luminosity Large Hadron Collider at CERN, the Deep Underground Neutrino Experiment at Fermilab, and the Electron Ion Collider at Brookhaven National Laboratory. To fully realize their discovery potential a new generation of software algorithms and approaches is required. Building these research software collaborations is challenging and inherently international matching the international nature of the experimental undertakings themselves. HSF-India will provide students, postdocs and early career personnel significant experience in international team science through engagement in a diverse research community.
