Back in the days I used to study statistical physics models, in particular how extreme value statistics may help characterize the geometry of objects known as fluctuating interfaces. After completing my PhD in this domain, I embarked in a new, complicated, and fascinating world: biology.

My research now focuses on bacterial gene expression and physiology. I address biological questions with an interdisciplinary approach, from wet lab experiments to data analysis to theoretical modelling. Sometimes it ends up with new questions. Most of the time, Monod already answered them.

Recent projects

Kinetics of adaptation of B. subtilis to changing environment.

When the carbon source feeding a population of bacteria is changed, cells need to produce the appropriate enzyme(s) in order to proliferate on the new substrate. We look at a particular carbon source substitution in B. subtilis and investigate the kinetics of adaptation.

Evolution of gene expression in Drosophila

During a first postdoc in Cologne, I participated in modeling how gene expression levels evolved in the Drosophila genus.

Fluctuating interfaces


Before I switched to the world of living systems, I used to do theoretical physics. During my PhD I studied extreme value statistics of growing interfaces, under the supervision of Grégory Schehr. In this work, we provided an original characterization of few classes of interfaces via the behaviour of the maximal size of their fluctuations. (for more details, visit the publications page)
