Sonia obtained her PhD in Biochemistry and Biotechnology in 2022 in the group of Prof. Anne Willems (Laboratory of Microbiology, University of Gent) and Prof. Sofie Goormachtig (VIB-UGent Center for Plant Systems Biology). During her PhD, she studied the effect of low temperatures on the microbiome of two cold tolerant plants, Valerianella locusta and Poa annua, and the model plant Arabidopsis thaliana. The aim was to identify bacteria able to alleviate cold stress in plants. She is now a postdoctoral scientist in the group of Prof. Sofie Goormachtig at VIB-UGent Center for Plant Systems Biology since 2023. As a part of the BOOSTER project, she investigates how drought shapes maize microbiomes to identify drought-enriched bacteria that might promote plant growth under this abiotic stress and understand their mode of action.

My career path

I am full professor at Ghent University and group leader at the VIB center of Plant Systems Biology in Belgium. I combine research and education because I think they cannot be separated and they strengthen each other. Hence, apart from my scientific activities, I am intensively involved in education and educational organization. 

My research career started in 1987 at the UGent focusing on how interactions between plant roots and neighboring organisms influence plant growth in a positive way.
Initially, the emphasis was on the symbiosis between legumes and rhizobia, resulting in the formation of new root organs, the nodules, in which the rhizobia reside and fix atmospheric nitrogen for the plant.  At that time, we studied the non-model symbiosis between the tropical legume Sesbania rostrata and the bacterium Azorhizobium caulinodans and could unravel the early signaling events and specific adaptations that have evolved to enable this peculiar nodulation upon water submergence. During my post-doc and early group leader career, we studied long-distance control of nodule organogenesis in the model legume Medicago truncatula and made significant contributions to understand how the nodule number is controlled.
During my early career, I went three times abroad for a prolonged period at the Laboratoire de Biologie des Sols, ORSTOM (Dakar, Sénégal) (Prof. Dreyfus), at the MSU-DOE, Plant Research Laboratory, Michigan State University (East Lansing, MI, USA) (Prof. De Bruijn) and at the ETH-Zürich, Institute of Plant Sciences (Prof. Potrykus), providing me both international connections and abroad research experience.

In 2005, I became professor at the Ghent University in the currently named Department of Plant Biotechnology and Bioinformatics. This department is also embedded in the VIB Center of Plant Systems Biology of the VIB. Since 2010, I am appointed full-time principal investigator of the Rhizosphere group at VIB. In my group, we still study the molecular communication between roots and rhizosphere microorganisms but the studies go beyond the rhizobia legume interaction as you can read from our web page. In 2017, I became full professor.

I find it very important that our basic research has valuable economic and societal relevance. Together with VIB colleagues, I am  very proud to have established the start-up Aphea.Bio (www.aphea.bio, 2017) focusing on the use of plant growth promoting rhizobacteria in agriculture. Recently, together with ILVO, I contributed to the start-up Protealis (https://www.protealis.com) aiming at the production of sustainable plant protein for Europe.
