Dr. Sonja Leitner

Expertise

Biologie, Botanik, Zoologie: I am an ecologist from Austria with a background in biogeochemistry and ecosystem research. At the moment I am working as Postdoctoral researcher at the International Livestock Research Institute (ILRI), in Nairobi, Kenya. ILRI is part of the CGIAR agricultural research network. My work focuses on the influence of livestock manure on soil greenhouse gas emissions and the cycling of carbon and nitrogen in soil.
