As a glacial/Quaternary geologist I have tought courses in glacial sedimentology and geomorphology, as well as glacial history and applied aspects of quaternary geology as hydrogeology, engineering geology and resource- and environmental geology. In 2017, in spite of my retirement, it was 'business as usual'. My replacement, Sven Lukas, is now in place since May 2018, and will take over my teaching.

Since 1st of January 2017 I am officially retired, so I suppose the correct title should be Professor Emeritus. However, not much has changed with regards to research. I am still very active within two of our research groups within Quaternary Sciences at the Department of Geology:(1) Glacial Processes, Sediments and Landforms and, (2) Reconstruction of Quaternary environments in Polar and mid-latitude regions - palaeoglaciology and climate history. Polar research has been close to my heart; since 1989 I have made extensive field work in polar/subpolar areas of both hemispheres (about 20 expeditions) on Greenland, Svalbard, Siberia in arctic Russia in the north and on Antarctica and Tierra del Fuego in the south.

Much of presently ongoing research centers around (i) the formation of drumlins in southern Sweden (and in general the formation of the glacial landscape), (ii) glacial history and palaeo-environmental change in southern Scandinavia for a period before the Last Glacial Maximum (70-30,000 years ago, Marine Isotope Stage (MIS) 3), (iii) glacial/postglacial palaeoenvironmental development in the Siljan area (Dalarna) in southcentral Sweden and (iv) palaeoenvironmental reconstruction in connection with Mesolithic (stone age) camp sites in northernmost Sweden (Norrbotten).  

In January 2019 I got a new 3-year SGU-funded project (together with Helena Alexanderson) entitled: "Sub-till sediments and deflation surfaces in southern Sweden (https://www.sgu.se/om-sgu/nyheter/2019/januari/lldelning-av-externa-forskningsbidrag-2019/)

News and activities:

September - October 2019: Field work (5 weeks) in southern Sweden for the SGU-funded project ”sub-till sediments and deflation surfaces in southern Sweden”. Reconnaissance of c. 70 gravel quarries for evaluation of best sites to be trenched for sedimentological investigations next year.

August 2019: Field work for my Siljan Lake district project ‘Quaternary geology from deglaciation into present time’. Peat bog coring in the Leksand area for searching evidence for an Early Holocene lake drainage event for Lake Siljan.

August 2019: Field investigation of possible grave mounds (Bronze Age?) at Selholmen close to Älvsbyn in Norrbotten (northernmost Sweden). Co-operation with Norrbotten Museum.

April 2019: Presentation of the new 3-year SGU-funded project "Sub-till sediments and deflation surfaces in southern Sweden" in Uppsala, at SGU's 'Research and Innovation Day', the 11th of April, with lecture and poster.

March 2019: Field work on Lake Orsasjön in Dalarna, coring lake sediments for my Siljan Lake district project ‘Quaternary geology from deglaciation into present time’.

January 2019:  I received a new SGU-funded SGU project together with Helena Alexanderson; "Sub-till sediments and deflation surfaces in southern Sweden (https://www.sgu.se/om-sgu/nyheter/2019/januari/lldelning-av-externa-forskningsbidrag-2019/). This will mean extensive field work in south Sweden during 2019 and 2020.

October, 2018: Lecturing for a week at UNIS in Longyearbyen, Svalbard, on Siberian glaciation history on the course ‘Arctic glacial and climate history’.

August, 2018: Started preliminary investigations in the Siljan area for an upcoming project: ‘Quaternary geology from deglaciation into present time’. The project aims at understanding the last deglaciation in the area and relations with the Baltic Sea-basin waters for the highest coastline development (the Ancylus Lake), as well as how the Siljan basins became isolated during isostatic uplift and the following lake development. In August, I started up with morphological ground control of LiDAR mapping, as well as mapping of the bottom topography of Lake Orsasjön with so-called 'multi-beam' mapping, and the distribution of lake sediment sequences with 'sub-bottom profiling'. A project application for future drilling programs has been submitted.
