Dr Yunyun Zheng
Postdoctoral Research Fellow in Soil Science
School of Agriculture and Food Sustainability

Researcher biography
The aim of Allie's research is to improve soil health for sustainable agricultural production and environmental protection. Her research spans the areas of plant-soil-microbe interactions, soil microbiology, nutrients cycling and the recylcing of organic wastes, currently focusing on (i) the development of advanced and novel methodologies for investigation of plant-soil-microbe interactions; (ii) dynamics of nutrients (N, P, K) and carbon in soils including greenhouse gas emissions; and (iii) soil carbon sequestration and persistence.
