Research Interests

My scientific interest is in the study of the complex process of morphogenesis, which comprises all the chemical and physical mechanisms at stake during development for multicellular organisms to acquire definite and robust shapes. My model system is the shoot apical meristem of Arabidopsis as this structure located at the tip of every stem is responsible for the emergence of all the aerial organs of the plant. I have a background in Molecular Biology but aim in using multidisciplinary approaches by combining experiments and modelling to answer complex questions of development. During my PhD, performed with Olivier Hamant in the Laboratory of Plant Development and Reproduction (Lyon, France), I was interested in the relationship between patterning and growth. I studied how mechanical forces resulting from shape changes in the meristem could influence gene expression. I have also looked at the influence of meristematic and post-meristematic growth on the spatial arrangement of the organs on Arabidopsis stems (phyllotaxis). In this post-doctorate where I joined the teams of Henrik Jönsson, James Locke and Elliot Meyerowitz at SLCU, I am looking more precisely at the mechanisms of patterning by studying the dynamics of gene regulatory networks in the meristem using both experimental approaches and computational modelling.
