Henrik Liljegren is a researcher in linguistics at Stockholm University (Sweden), where he received his PhD in 2008. He is one of the co-founders of Forum for Language Initiatives (FLI), a resource centre for the many language communities in Pakistan’s mountainous North, where he served for several years while also conducting fieldwork in the country, primarily in the Palula community of Chitral. His main research interests are areal-linguistic typology, language contact, Indo-Iranian languages, case alignment, phonology and lexicography. Apart from research per se, Henrik Liljegren has been engaged in language maintenance efforts and orthography development, mentoring language activists in local communities to collect and organize data, and in building networks between local communities and organizations. He is presently leading a Swedish Research Council project, investigating language contact and relatedness in the Hindukush-Karakorum region.
