My dissertation from 1983 deals with the phonology and morphology of Kammu (aka Khmu, Kmhmu, etc.), an Austroasiatic language spoken in northern Laos and adjacent areas of Vietnam, Thailand and China by some 500.000 people. The work on Kammu continues in my present research projects.

Another research interest is Mongolian. Together with my coworkers Anna Tsendina, Anastasia Karlsson and Vivan Franzén I have written a comprehensive analysis of the phonology of Mongolian including its phonological develoment from the time of Chinggis Khan to the modern Mongolic languages. I have also translated into English and published the Kalmuck-Swedish dictionary of the missionary Cornelius Rahmn (1785-1853).
