Mutez Ali Ahmed

Research Associate

At Soil Physics until 03/2023
e-Mail: Mutez.Ahmed(at)uni-bayreuth.de

I received my B.Sc. (Agricultural Engineering, Hons, Class one) and M.Sc. (Agricultural Engineering, Distinction) from Department of Agricultural Engineering, University of Khartoum and PhD (summa cum laude) from University of Göttingen, Germany. I was an Assistant Professor of Soil-Plant Interaction at the Department of Land, Air and Water Resources, University of California, Davis from 2021-2023. As of 02/2023, I'm a Professor of Root-Soil Interaction at the School of Life Sciences, Technical University of Munich and a research associate at the Chair of Soil Physics, University of Bayreuth.

The primary objective of my research is to understand the basis of crop adaptation to water-limited environment. I am particularly interested in identifying roots and rhizosphere traits that improve the acquisition of resources from soil.
