Dr. Ute Sass-Klaassen
Wageningen University, Centre for Ecosystem Studies, Forest Ecology and Forest Management, P.O.Box 47, 6700 AA Wageningen, Netherlands

As associate professor at Wageningen University I am involved in teaching and research on forest ecology, wood biology and dendrochronology. My major research interest is to use wood anatomy as an archive to understand how woody species react to environmental factors. I get inspired by collaborating with colleagues from other disciplines such as ecophysiology, forest modelling, geology, geochemistry, genetics and strongly believe that innovation in research is largely based on interdisciplinary approaches! I see the ATR as a perfect platform where several generations of researchers share knowledge and establish collaboration to advance our research field, but also seek for integration with other disciplines to solve important research issues.

Dr. Giovanna Battipaglia

Department of Environmental, Biological and Pharmaceutical Sciences and Technologies, Second University of Naples, Italy

I’m a plant ecologist with research specialization in ecophysiology, and dendroecology. I’m currently researcher in Ecology at Second University of Naples (Italy) and Associate Professor at Ecole Pratique des Hautes Etudes, Montpellier (France). I have a long expertise in ecosystem carbon dynamics and in using stable isotopes (with conventional and laser technologies) as a tracer for physical and biological processes. Being on the board of ATR provides an amazing opportunity to build and strengthen collaborations with “young and more experienced” wood-scientists and I’m sure our community will keep growing in number and quality! I believe that this is an exciting and challenging time for our Tree-ring Association since our multi-discipline approaches and skills will help solve emerging global problems!


Dr. Neil Loader

Department of Geography, University of Wales, Swansea SA2 8PP, UK

I am employed as a lecturer at Swansea University UK, where I teach Physical Geography and manage the Stable Isotope Mass Spectrometry Laboratory. My research focus is in the field of isotope dendroclimatology, but I also have interests in historical dendrochronology, blue intensity and the development of field and laboratory techniques.
