I am a microbial ecologist interested in the factors affecting the growth and activity of plant beneficial bacteria.

Plants depend for their health and growth on naturally-occuring probiotic microbes that provide nutrients, growth hormones and antibiotics to the plant. Such probiotics can be used to replace pesticides and reduce the use of fertilizers, forming a corner stone of sustainable agricultural practices. In order to fully exploit this potential, we need to understand better the life of soil bacteria. I merge in my research community ecology, evolutionary biology and phytopathology to understand and master beneficial plant-microbe interactions.

Current priority research topics of my team include:

 -Development of multispecies probiotic consortia to enhance plant health (Simone Weidner, NWO-funded, and Tianjie Yang, CSC-funded,collaboration with Nanjing Agricultural University ): Mixing probiotic microbes may help combine the best out of the single isolates. In order to develop successfull consortia we combine comparative genomics and biodiversity - ecosystem functioning relationships to reveal the rules for the assembly of the perfect community,

-Assembly of the rhizosphere microbiome (Jie Hu &Wu Xiong, CSC-funded, collaboration with Nanjing Agricultural University) : Microbial communities associated with plant roots are very dynamics. We apply a metacommunity framework to track the changes in community composition and determine which configurations best support plant health. We test for instance self-assembly processes and the importance of metacommunity structure on microbiome structure and function.

-Development of multispecies microbial consortia to remove pollutants (funded by State Key Laboratory for Pollutant Removal and Resource Reuse, Collaboration with Nanjing University): We develop species consortia best able to remove organic pollutants from soils, supporting recovery of contaminated soils

-Protozoa and plant growth (Zhilei Gao, CSC-funded, Ida Karlsson, Swedish Research Counsil -funded): Protozoa are ubiquitous microorganisms and the main predators of bacteria in soil. As such, they have a strong impact on community structure and function.We investigate whether protozoa favor beneficial microbes in soil and if they can be used to enhance plant health in a sustainable way.

-Modulation of plant stress by root-associated microbes (Mohammad Ravanbakhsh, Iranian ministry of Education-funded, collaboration with the Ecophysiology group of the Utrecht University): Plant live in a complex environment and must adapt to different stressors. We investigate root-associated bacteria that reduce ethylen levels, an important hormone involved in stress response. We test the effect of these microbes on the ability of the plant to cope with common environmental stressors such as heavy metals and flood.

Research interests

I investigate the ecology and evolution of plant-associated microbial communities their impact on plant health. I use bacteria as model system to understand how biodiversity and global change effects interactively affect community performance and evolutionary dynamics. I have developed an interdisciplinary approach combining theoretical models and genomic data with laboratory and field experiments to predict microbial community function and feedbacks on plant performance.

I strive to make my results available to society and am actively using my discoveries to develop sustainable biological control strategies in dialogue with public and private stakeholders.


Keywords: Biodiversity-ecosystem functioning, predator-prey interactions, microbial ecology, evolution, plant-microbe interactions, sustainable agriculture.

Teaching philosophy

My teaching is centred on the early integration of students in practical work. I actively support students in the process of setting up independent, self-determined research. I apply these goals in seminars and practical classes. In the context of supervision of bachelor- and master theses, and take a special care to assist and motivate students to publish their original work in peer reviewed journals (See Weidner et al 2015, Latz et al. 2012, Becker et al. 2012).

General project description 

Ecosystems of the future

Two of the most pressing issues facing our environment are climate change and biodiversity loss. Human activities are resulting in a sharp decline in biodiversity, while at the same time, climate change is impacting the world's ecosystems. It long been assumed that biodiversity can help ecosystems be more resistant to climate change, but if and how this occurs remains unknown. UU BioCliVE mimics ecosystems of the future, thereby allowing us to understand the mechanisms by which biodiversity helps to buffer ecosystems against potential harmful effects of climate change. Such knowledge will be critical as we develop management plans for the future that help to maintain biodiversity and preserve ecosystem functioning.
