Narrative Summary
I am permanently employed on a teaching position at the Dept. of Physical Geogr. and Quaternary Geol., Stockholm Univ. I was promoted to Full Professor on 1 July, 2004. My research concerns the thermodynamics of polythermal glaciers and ice sheet hydrology comparing the present Greenland Ice Sheet and the former Fennoscandian Ice Sheet. I also have several ongoing collaborations dealing with glacier mass balance and climate relationships with ETH-Zürich, Univ. of Innsbruck, Univ. of Gothenburg and within Stockholm Univ. I have been associated with Tarfala Research Station since 1985 and have run and developed the station environmental monitoring program in particular the world´s longest record of mass balance measurements on Storglaciären. I am currently Subject Responsible (in Physical Geography), and therefore in charge of the PhD education, at my department. I supervise several graduate students. I have published 48 papers (h-index: 15) in international peer-reviewed journals, including one paper each in Nature and Science. Several manuscripts are also in their final stages of preparation. I have co-written a book on glaciology aimed for Swedish undergraduate students, one manual for mass balance measurement training published by UNESCO/IHP as well as collaborated on a new standard for mass balance terminology also published by UNESCO/IHP. I have served as Vice President of the International Association of Cryospheric Science (IACS). Through IACS I have also headed a UNESCO training course on mass balance measurements in New Delhi (2002) and been an invited keynote speaker at the third World Water Forum in Kyoto (2003). I am Editor-in-Chief of the international journal Geografiska Annaler. I am a contributing author for the 2007 International Panel on Climate Change (IPCC)-report (WG-1, Ch. 4).
