Welcome to my homepage!
The main idea with
dendrogbg.com is to provide insight into my field of research, which is
climatology, with a focus on past climates i.e. paleoclimatology (mainly
working with tree rings), and also information about my research
activities. The name of the site is derived from the Greek word for tree
(dendro), and gbg is a shortening of Göteborg (Gothenburg), the town in Sweden
where I work and live. Presently this site is a bit basic, but as time goes by,
more information will be added.
For those of you who do not
know me, here is a short introduction (focusing on academia): I am Professor
in Physical Geography at the Department of Earth Sciences, University of Gothenburg, Sweden.
Additionally, I'm Vice Prefect with responsibility for the Climate research and
education section within the Department. I got my MSc and PhD at Stockholm
University (Department of Physical Geography and
Quaternary Geology). In 2003 I moved to the west coast of Sweden and became a member of the
Regional Climate Group (RCG) formed in 1995 by
Professor Deliang Chen. Coming here I
founded the Gothenburg University
Laboratory for Dendrochronology (GULD).
I had a postdoc position
(subsequently turned into a visiting scientist position) at the Laboratory for Climate Studies, National Climate Center,
Beijing, China from 2003-2007. I'm director (together with Prof. Yu
Liu) of the Sino-Swedish Centre for Tree-Ring Research (SISTRR), a collaboration
centre between the University of Gothenburg and Institute of Earth Environment, Chinese Academy of Sciences in Xi'an, China.
My research is focused on regional climate variability in Europe and Asia
from the past (last 2000 years) to the future (next 100 years), the effect of
climate change on terrestrial and marine ecosystems, and the role of the
large-scale circulation in the oceans and atmosphere on climate variability in
Using high-resolution proxies, mainly tree rings, I reconstruct past
climate changes (e.g. temperatures, drought and precipitation, and the atmospheric
circulation) on different temporal and spatial scales. My work has mainly been
conducted in North Europe and China, but I have also projects in Canada and
North Africa. These reconstructions are useful in understanding past climate
variability under (more or less) natural conditions, i.e. before man had a
significant impact on climate. Thus, these reconstructions can help us assess
how much we have affected climate in the last century. Moreover, climate
records going far back in time can help us better understand the climate
system, e.g. how climate in different regions is related to that of other,
remote, regions - teleconnections. Such teleconnections are due to the
large-scale circulation in the oceans and the atmosphere, and this is a special
focus of my research.
I also do research on contemporary climate change, presently directed
towards better understanding the impacts (and feedbacks) of large-scale
circulation change (e.g. the NAO and the Asian Monsoon) on climate in the
future, but also on sea-ice variability in the Arctic, glacier variability in
northern Scandinavia, changes in the growing season and the impact of climate
change on marine ecosystems.
