Internationally active dynamic and innovative soft matter physicist with strong interest also in materials science, physical chemistry and—very much so—cross-disciplinary activities. The driving force is a deep fascination and enthusiasm for the scientific beauty of the field as well as the diverse application possibilities.

Experience from multiple world-class academic research & teaching environments in five countries on three continents. Long-term core expertise in liquid crystals—thermotropic and lyotropic—expanded with activities in electrospinning, microfluidics and colloids, leading modern liquid crystal science to new directions, with wearable technology and soft robotics being our main applied foci.

Active in relationship building and networking, with a record of organizing and leading international multi-expertise scientific teams.

Efficient in delivering complex information to diverse audiences thanks to enthusiasm and good skills in written and verbal communication, with support of multiple digital media as well as hands-on experiments and demonstrations.
