Research Interests

In June 2013, I joined the Braybrook Team with the aim of understanding the mechanical principles governing plant cell growth. My project will deal with the characterization of the cell wall during Arabidopsis hypocotyl elongation and the logistics of material transport and deposition. I will be also working on the biochemical and mechanical components affecting the maintenance of cell connectivity during cell expansion and tissue development.

Previous work:
Dipl. Agricultural Engineering, Lebanese University, Beirut.
M.Sc. Horticultural Genetics and Biotechnology, Mediterranean Agronomic Institute of Chania, Greece. With Panagiotis Kalaitzis.

My project focused on the characterization of prolyl 4-hydroxylases and their effect on plant cell wall and tissue senescence under different stress conditions. During my masters, I had the opportunity to learn about plant genetics and molecular biology.
Ph.D University of Montreal, Canada. With Anja Geitmann
My project on the growth of anisotropic cells allowed me to combine my prior expertise on plant biology and molecular techniques with numerous microscopy techniques with which I became familiar under Dr. Geitmann's supervision. I focused on the plant cytoskeleton and cell wall and their roles in plant cell growth, development and tropic behavior using the pollen tube as a model system.

Post-Doctoral Researcher, Laboratory of Plant Development and Interaction, University of Guelph, Canada. With Jaideep Mathur

In the Mathur lab, I have expanded my expertise in live cell imaging of cellular compartments and organelles, and the use of multiple fluorescent probes to co-track different cellular compartments. I worked on the interactions between microtubules and microfilaments as well as cellular organelles in the early stages of infection of Arabidopsis plants with the model fungal pathogen Colletotrichum destructivum. I also worked on the characterization of the cell wall components of ARP2/3 mutants which are characterized by an abnormal cellular adhesion.
