We are hiring a postdoc !

Dear colleagues,

I have the pleasure to announce to you that we have an opening for a postdoctoral position in Brussels.

The postdoc will be based in the trioS.lab ( at the Université Libre de Bruxelles (ULB) and will have to develop the project entitled “Biomimetic Fog Nets” interacting with an interdisciplinary network including the GRASP at the University of Liège ( The project description can be found in the attached document.

We are looking for a strong and creative experimentalist that can lead research projects, have strong collaboration skills and is able to work in an interdisciplinary environment. Background in soft matter, physical hydrodynamics and/or material science is highly desirable.

Applicants should send a letter of motivation, CV, list of publications and 2 or 3 recommendation letters to Denis Terwagne (

Ideal starting date is March 1st, 2017 and application will be opened until the position is filled. The contract is for one year with a possible extension of one year.

Could you please widely diffuse this announcement to your contacts and around you ?

I wish you the very best for this new coming year,

Denis Terwagne

At the national science festival, Playful Science

We are participating to the national Science festival Playful Science 10 organized by Science on Stage on the 22nd of october 2016.

Science et Culture and Hervé Caps from the University of Liège and Denis Terwagne from the Université Libre de Bruxelles (ULB) are organizing an exhibit on the physics of plants.



The group is growing

Jehan Charlier, after completing its master degree in Physics and his master thesis in our lab, is joining our group for a Ph.D thesis. For his project, we will collaborate with Pierre Colinet from the “Transferts, Interfaces et Procédés” (TIPs) at ULB.

Curvature-induced symmetry breaking determines the wrinkling pattern in Nature Materials

Our paper on the Curvature-induced symmetry breaking determines elastic surface patterns” has just been published online in Nature Materials !

The wrinkling morphologies of our curved elastic bilayer materials are further analyzed in collaboration with a team from the Math department of MIT. The pattern formation is described here by deriving a generalized Swift-Hohenberg theory. This theory, universally applicable to macroscopic and microscopic systems, can be extend to arbitrarily shaped surfaces, thereby solving a longstanding problem in elasticity theory.
