The Himalayan Languages Project, launched in 1993, is a research collective based at Leiden University and comprising much of the world's authoritative research on the lesser-known and endangered languages of the Himalayas, in Nepal, China, Bhutan, and India. Its members regularly spend months or years at a time doing field research with native speakers. The Director of the Himalayan Languages Project is George van Driem; other top authorities include Mark Turin and Jeroen Wiedenhof. It recruits grad students to collect new field research on little-known languages as the topics for their Ph.D. dissertations.
