Research

How does the molecular structure of the soft matter affect its properties and functions at the macroscale? How can scientific ideas lead to the acceleration of innovation? An interdisciplinary background across the field of Polymer Physics brings together competences essential to lead the success of a research project - and a bit more. The subjects of investigation range from homopolymers to copolymers and blends, for applications such as sustainable energy storage and conversion, lightweight & recyclable solutions.

To shed light on the interplay between the structure and dynamics of polymers as well as their response to external stimuli, a series of advanced characterisation techniques is employed providing versatile viewpoints: they include analytical, spectroscopic, structural, thermodynamic and mechanical probes. Below you may read the latest results as published in international refereed journals. Currently I work at the Innovation Headquarters of Borealis in Linz, Austria, developing next generation polyolefin compounds for Energy solutions for our society.
