PhD Students

Häerzlech Gléckwonsch, Najiya!

We here at ESMP want to congratulate the latest Docteur de l'Université du Luxembourg en Chimie, Najiya! Najiya successfully defended her Ph.D. thesis, Fabrication and Tailoring of Liquid Crystalline Elastomer Tubes: Toward Bio-Compatible Microactuators for Organoid Cultures, on 10 March.

Najiya's PhD Defense


Häerzlech Gléckwonsch, Najiya!

Welcome Tadej and Churchill!

As our first post for 2025, it is our pleasure to welcome our newest group members, Dr. Tadej Emeršič and Mr. Churchill Agoni, to ESMP!

Photo Tadej

Originally from Slovenia, where he completed his Ph.D., Tadej comes to us from the University of Chicago, where he worked as a postdoc in the group of Juan de Pablo. He joins us on the INVISIMARK project, a project in cooperation with the Luxembourg Ministry of Defense, in which he'll be working with us for (at least) the next year and a half on the use of CSRs for secure identification purposes.


Churchill comes from Nigeria and joins us after his Master's studies in Photonics at the University of Eastern Finland in Joensuu. He'll be working on the SHADOW project, a collaboration with the University of Ljubljana, on studying ferroelectric nematic liquid crystals under confinement.

Congratulations to Larry!

Congratulations to Larry, Shameek, Manos, and Jan on their recent publication, "Elastic Sheath–Liquid Crystal Core Fibres Achieved by Microfluidic Wet Spinning" published recently in the Journal of Materials Chemistry C!

In this article, they present the wet spinning of core–sheath liquid crystal-filled elastomer fibers using a microfluidic spinneret adapted from the normal techniques they use to produce shells and droplets. In particular, when we spin fibers containing a cholesteric liquid crystal, the result showing brilliant reflected colors as a result of the liquid crystal alignment within the fiber core. These fibers can be highly stretchable and show color changes upon heating and cooling.

Congratulations to Anjali!

Congratulations to Anjali, Jampani, and Jan on their new article published in Langmuir: "Realignment of liquid crystal shells driven by temperature-dependent surfactant solubility"

This is the study of nematic LC shells stabilized by temperature responsive surfactant. Study shows how one can change the alignment of LC just by varying the temperature. Click here for the full article.

Anjali gets featured on FNR's Spotlight on Young Researchers!

Our Ph.D student Anjali Sharma was featured on FNR's Spotlight on Young Researchers blog! :D

Anjali works on forming liquid crystal shells and she works on trying to stabilize them using different surfactants and polymers.

Anjali and the team (Jampani, Nikolay and Jan from our group) + others from Prof. Ralf Stannarius's group in Magdeburg, Germany, observed LC shell behavior in a micro gravity environment made possible through several parabolic flights initiated in a plane provided by the German Aerospace Center (DLR)

Read about & see her experience here on the FNR's site: Spotlight on Young Researchers: Anjali Sharma

Anjali’s PhD is funded by the FNR’s PRIDE programme in the framework of the Doctoral Training Unit (DTU) MASSENA, which has the goal to improve the understanding and the performance of materials used in sensing and energy harvesting

Rijeesh Nikolay

Welcome to our new post-doc Rijeesh (left) and phd Nikolay (right) who have joined our team. Rijeesh will be working on making cholesteric LC shells for reflector tags. While Nikolay will aim to generate tube-shaped liquid crystal elastomer actuators for biomedical applications.

Camila Honorato joins as doctoral candidate

Camila
We welcome Camila Honorato as a member of our group! She will be working as a doctoral candidate in the MISONANCE project, carried out in collaboration with the team of Prof. Tanja Schilling at PhyMS, UL. Camila will study the self-assembly of water-suspended cellulose nanocrystals into lyotropic liquid crystal phases, and how this self-assembly competes with the tendency of electrostatically charged nanorod suspensions to arrest into a jammed state. She will interact closely with Anja Kuhnold from Prof. Schilling's group, who is doing theory and computer modeling corresponding to Camila's experiments.

Catherine Reyes joins the group

Catherine
It is with great pleasure that we welcome our new Ph.D. candidate, Catherine Reyes, coming from Cornell University where she carried out her Master studies with Prof. Margaret Frey. Catherine should have arrived already in September but the paper work for allowing a US citizen and Cornell graduate to start as Ph.D. candidate in Luxembourg turned out to be beyond our wildest imagination… Anyway, she is finally here and she will be working full time on liquid crystal-functionalized electrospun fibers for wearable technology.
