Arrival of Bruno Guillotin at IPS2

Dr. Bruno Guillotin, Appointed CNRS Research Scientist at IPS2 and ATIP Avenir Laureate

Bruno Guillotin has joined the IPS2 unit (Institute of Plant Sciences Paris-Saclay) as a CNRS Research Scientist. He was recruited in February 2025.

After studying Plant Biology and Physiology, he completed his PhD between 2013 and 2016 at the Plant Science Research Laboratory (LRSV – Toulouse) under the supervision of Guillaume Bécard and Jean-Philippe Combier. His doctoral work focused on the autoregulation of arbuscular mycorrhizal symbiosis in Medicago truncatula.

Following his PhD, he turned his attention to the study of root development in various plant species as a postdoctoral researcher in Kenneth Birnbaum’s group at New York University. There, supported by a Human Frontiers Long-Term Fellowship, he developed numerous protocols for single-cell transcriptomics (single-cell RNA-seq), which he implemented to study gene evolution across agronomically relevant species (maize, sorghum, millet), as well as to investigate cell regeneration in the roots of Arabidopsis thaliana.

In 2025, he was appointed as a CNRS Research Scientist and was also awarded the CNRS–INSERM ATIP-Avenir grant.

At IPS2, Bruno Guillotin’s research focuses on understanding how plant cells communicate through plasmodesmata, aiming to identify which proteins and peptides move from one cell to another and contribute to organ morphogenesis in plants. His work combines single-cell RNA-seq, proteomics, genomics, and bioinformatics approaches.
