The research in the group deals with the self-assembly processes occurring in soft matter, our main fundamental science foci being on liquid crystals, colloids and polymers. We are particularly interested in spontaneous long-range ordered structure formation on the nano- and microscales, driven by the unique ordering processes of liquid crystals. We work with the thermotropic as well as the lyotropic class of liquid crystal, often with nematics (chiral or non-chiral) and sometimes with smectics, and when appropriate, we polymerize the phases using reactive mesogens. Our specialty is to study liquid crystalline self-assembly in unconventional contexts, using e.g. electrospinning and microfluidics to produce new composite structures. Apart from investigating their properties and behavior from a fundamental scientific point of view, we also explore their application possibilities, in particular in wearable technology, soft robotics, advanced composite materials, and in secure authentication.

The map below gives a pictorial overview of our main current activities, interests, and some brief info on previous work.
Currently, the group’s research is organized around the following projects:

  • INTERACT : An ERC Consolidator Grant-funded project dealing with wearable technology, soft robotics, and dynamic pattern generation, based on liquid crystal-functionalized electrospun fibers, liquid crystal elastomer actuators, and cholesteric liquid crystal shells, respectively.

  • SSH : SECURITY IN THE SHELL. An interdisciplinary project in which materials and computer science join forces to produce, characterize and utilize cholesteric liquid crystal shells in authentication applications. This research is carried out in collaboration with Dr. Gabriele Lenzini from the APSIA group at the Luxembourg Interdisciplinary Center for Security and Trust (SnT) and is funded by the CORE scheme of the Fonds National de la Recherche Luxembourg (FNR).

  • LAB’RINTH: Liquid crystal-bead reflectors illuminating the needle in the haystack.
