Gebert, J.


Julia is a biologist and soil scientist, educated at the University of Hamburg, Germany. She has been principal investigator in several projects concerning the biological treatment of landfill gas. Another focus of her work concerns anaerobic carbon cycling in river sediments and the beneficial use of dredged material as construction material, e.g. in dikes. The strength of her work lies in crossing traditional discipline boundaries to investigate complex problems, combining concepts and methods from soil physics and chemistry, microbiology and engineering. The use of fundamental research to address applied questions further earmarks her work. After several years as head of the Environmental Services Unit at Hamburg Port Authority she joined TU Delft in Mai 2017 where she now holds a position as associate professor in the section Geo-Engineering.
