Dr. rer. nat. Marie-Cécile Gruselle
Research Areas: Forest Soils, Nutrient Cycling
E-mail: mariececile.gruselle@maine.edu
Phone: 207–581-2946
Office: 116 Deering Hall

Bio: Dr. Gruselle received her Forest Engineer degree (2002) from the Agricultural University of Gembloux (Belgium, now called the University of Liège Ulg). She received her PhD in Environmental and Forest Sciences (2009) from the Albert-Ludwigs University (Freiburg im Breisgau, Germany) studying litter decomposition in mixed Norway spruce – European beech forests. Prior to coming to Maine in May 2012, she worked as an exchange research Fellow at Utah State University (2009) and as a post-doctoral scientist at the Friedrich-Schiller University (Jena, Germany, 2010-2012) where she investigated the effects of tree species on soil organic matter quality and sequestration. She is currently working with Ivan Fernandez in the Forest Soils Program at the University of Maine in the scope of the NSF funded project on the Biogeochemical Controls on altered Nitrogen Cycling in the Third Decade of Whole-Watershed Simulated N deposition.

Current Research: My research activities in the Forest Soils Program at the University of Maine focus on investigating the effects of long-term (> 23 years) acidification and nitrogen (N) fertilization on soil processes such as N mineralization, litter decomposition, and soil organic matter sequestration using the heavy N isotope (15N) as ecosystem tracer. In addition, I am very much interested in comparing the impact of the long-term acidification and N fertilization on soil processes in hardwood stands versus softwood stands. This research takes place in the paired watershed research site at Bear Brook Watershed in Maine (see http://www.umaine.edu/bbwm/ for more details about research conducted at Bear Brook).
