Dr Judith Rathjen
Research Officer
School of Agriculture, Food and Wine
Faculty of Sciences, Engineering and Technology
I have been working as a research in rhizobiology since 2018 in Matt Denton's group. I have a strong interest in compatibility of commonly used seed pesticides, fertilisers and trace elements with rhizobia, using microbiological and plant-based techniques. Other interests include the global diversity of rhizobia in countries without a history of inoculation and the N fixation efficiency of diverse strains.
