PROFChristoph Mueller

Christoph Müller has been Professor of Soil Science at University College Dublin  since 2007 and Professor of Experimental Plant Ecology at the Justus Liebig  University Giessen since 2009. After an apprenticeship as a gardener (ornamental  plants), Müller studied Horticulture in Berlin, followed by a MSc in Soil Water  Management at Reading University and a PhD in Soil Science at Lincoln University,  New Zealand. The focus of his research is to understand the impact of climate  change on ecosystems. In Giessen he is leading a Free Air Carbon Dioxide Enrichment study on  grasslands, which is one of the longest running field climate manipulation studies worldwide, running  for more than 25 years. To understand the processes, he has developed a number of nuclear methods to  quantify the rates of elemental transformations in the soil (N cycle, P cycle, C cycle) and identify the  processes leading to greenhouse emissions. Since 2014, he has been working as an expert for the  IAEA, specifically in training methods to quantify greenhouse gas emissions and since May 2025 he established one of the first Uniteds Nations collaborating centres on agroecology and cliamte change in Europe, the "Liebig Centre for Agroecology and Climate Impact Research". UCD is a key partner of the Liebig Centre.
