Our current group members

Stéphanie Robert, professor

I received my PhD at Paris XI University-Orsay, France in 2005, which was followed by two postdoc positions, the first at University of California, Riverside, USA and the second at VIB-Ghent University, Belgium.
I at set up my lab at Umeå Plant Science Centre in 2010. As a professor at the Swedish University of Agricultural Sciences, I am involved in teaching at both Bachelor and Master levels and I am responsible for the microscopy facility at Umeå Plant Science Centre. However, the majority of my working time is spent on research, together with my group members and collaborators.
In my free time I love photography, baking and crafting.

Siamsa Doyle, researcher

I received my PhD in 2010 at University College Dublin, Ireland.
I joined the Robert group in 2010, shortly after Stéphanie set up her lab at Umeå Plant Science Centre. In previous years, I have focused on the roles of endomembrane trafficking, auxin transport and auxin signalling on the regulation of root responses to gravity in Arabidopsis and adventitious rooting in poplar. More recently, I have shifted my focus towards unraveling the roles of auxin gradients, cell wall components and molecular signalling events in regulating the fascinating jigsaw puzzle shape of leaf epidermal pavement cells in Arabidopsis.
In my spare time I enjoy singing, dancing lindy hop and hanging out with my little boy.

Sara Raggi, postdoc

I completed my PhD in 2016 at Sapienza University of Rome, Italy. During my PhD, I also spent 6 months at Institut Jean-Pierre Bourgin-INRA, Versailles, France, funded by a short-term EMBO fellowship.
I joined the Robert group in 2016. I study the role of the cuticle during apical hook development in Arabidopsis seedlings. Furthermore, I investigate the interplay between the cuticle and phytohormones in this developmental context.
In my free time I like listening to music, playing games and doing DIY projects.

Sijia Liu, postdoc

I completed my PhD in 2017 at China Agricultural University, China and Forage Improvement Division, Noble Research Institute, USA.
I joined the Robert group in 2017. My research project is focused on discovering the molecular regulators of pavement cell shape in leaves of Swedish aspen (poplar) collections using multi-omics approaches.
In my free time, I like singing, dancing and playing instruments.

François Jobert, postdoc

I joined the Robert group in 2019. I conduct my postdoc research on white lupin root development under the co-supervision of Stéphanie Robert at Umeå Plant Science Centre and Benjamin Péret at the French National Centre for Scientific Research (CNRS) in Montpellier, France. More specifically, I investigate the roles of auxin and cell wall remodelling during root emergence in this new legume model.
In my spare time, I enjoy exploring nature by day and playing music by night. Mushroom hunting is also a big passion during the Autumn!

Ying Wang, postdoc

I received my PhD in 2019 at Paris-Saclay University, Institut Jean-Pierre Bourgin, Versailles, France.
I joined the Robert group in 2019. My project investigates how auxin signalling is involved in the control of cell adhesion in Arabidopsis thaliana, using auxin antagonists and the cell adhesion defective mutant quasimodo, in a project co-supervised by Stéphanie Robert and Stéphane Verger, Umeå Plant Science Centre. Additionally, by testing the effects of molecules isolated as restoring this cell adhesion phenotype on auxin signalling, I aim to discover new molecules of interest to target auxin signalling pathways.
In my spare time, I enjoy painting and hand crafting.

Petra Marhava, postdoc

I received my PhD in 2015 at VIB, Ghent University, Belgium and Institute of Science and Technology in Austria (IST Austria), followed by a postdoc position at University of Lausanne, Switzerland.
I joined the Robert group in 2020. I am interested in how plants cope with temperature stress at a cellular level, with focus on the root.
All my free time is spent with my twins, but when they sleep, I am happy to watch TV series.
