Research
- Research
Master 1 Internship – Maynooth University (Republic of Ireland) – Supervised by Prof. Emmanuelle Graciet
My Master 1 research project focused on the study of interactions between the protein degradation pathway known as the N-degron pathway and epigenetic regulatory mechanisms, in particular the H3K9 acetylation mark (H3K9Ac), in the plant model Arabidopsis thaliana.
Master 2 Internship – Université Clermont Auvergne – Supervised by Dr Olivier Mathieu and Dr Thierry Pélissier
This work, which was extended as part of my PhD project, investigated the role of the M1M and M2M DNA motifs in the protection mechanisms against Polycomb-mediated silencing involving the MAIN/MAIL proteins.
PhD Research – Université Clermont Auvergne – Supervised by Dr Olivier Mathieu and co-supervised by Dr Thierry Pélissier
The research group of Olivier Mathieu discovered a novel mechanism involving PMD-domain proteins (MAIL/MAIN) that counteracts Polycomb-mediated silencing (Ikeda et al., 2017).
My current research builds on this discovery and aims to further elucidate the molecular mechanisms underlying this process, both at the level of gene regulation and transposable elements.
- Teaching
I teach plant physiology, ecology, and plant diversity at all undergraduate levels (Years 1 to 3), as well as plant physiology within the Preparatory Programme for Scientific Studies (PES).
Publication
Plant mobile domain protein-DNA motif modules counteract Polycomb silencing to stabilize gene expression.
