RESEARCH PROFILE

Research group website: http://tps.phys.tue.nl/janssen. Liesbeth’s research describes materials that are far from thermodynamic equilibrium, ranging from non-crystalline polymers and colloidal glasses to living cell models. The Non-Equilibrium Soft Matter group studies the structural, dynamical, and mechanical properties of such materials using a combination of statistical-mechanical theory, analytical modeling, and computer simulations. This research provides new insights into the relation between the microscopic structure and the emergent dynamics of soft and living matter, and may lead to, for example, smart materials that are capable of adapting to their surroundings.

There are three key research areas: glass formation, which looks at amorphous non-crystalline solids, covering a wide range of substances, from gels to granular materials. The second area is active materials, which are composed of particles that can convert energy into autonomous motion. This requires development of new statistical physics. Potential applications range from bio-sensing to targeted drug delivery. The third area, bio-inspired and living materials, combines elements of the previous two. Studying the physical principles underlying responsive behavior in living systems may result in design and control of bio-inspired and smart materials.

Non-Equilibrium Soft Matter research is fascinating as it allows us to discover completely new areas of physics that represent a departure from classical statistical mechanics and thermodynamics. Applications range from creating self-healing plastics to cancer research to revolutionizing computer memory storage.”

ACADEMIC BACKGROUND

Liesbeth received her PhD in Theoretical Chemistry (cum laude) from Radboud University Nijmegen in 2012. Following postdoctoral stays at Columbia University in New York and Heinrich-Heine University Duesseldorf, she established her own group at Eindhoven University of Technology in 2017. In 2020 she was promoted to Associate Professor (with ius promovendi), and since 2022 she also holds the Chair of the group Soft Matter and Biological Physics. Liesbeth is an elected member of the KNAW Young Academy and she is the recipient of several academic awards, including the Huygens Talent Scholarship, Unilever Research Prize, Rubicon fellowship, Niels Stensen fellowship, Alexander von Humboldt fellowship, Mildred Dresselhaus award, and NWO Vidi award.

THE GLASS PHASE: A PHYSICS MYSTERY

In physics the glass phase is deemed to be a special form of a solid. While the material feels hard, it lacks a regular crystalline structure. Physicists still cannot explain the transition from a liquid to this special solid form. TU/e physicist Liesbeth Janssen is now trying to write the definitive universal theory of glass. Solving this mystery will bring numerous applications within reach. Fast-working computer chips, for example, or recyclable plastic. The glass phase can even help us better understand asthma and cancer metastasis.
