  The new field of gravitational wave astrophysics requires a growing pool of
students and researchers with unique, interdisciplinary skill sets. It also
offers an opportunity to build a diverse, inclusive astronomy community from
the ground up. We describe the efforts used by the North American Nanohertz
Observatory for Gravitational Waves (NANOGrav) NSF Physics Frontiers Center to
foster such growth by involving students at all levels in low-frequency
gravitational wave astrophysics with pulsar timing arrays (PTAs) and
establishing collaboration policies that ensure broad participation by diverse
groups. We describe and illustrate the impact of these techniques on our
collaboration as a case study for other distributed collaborations.
