Helmut Münstedt is retired professor and former Head of the Institute of Polymer Materials of the Friedrich-Alexander-University Erlangen-Nuremberg, Germany. He is a leading expert in polymer science and rheology and made important contributions to relationships between structure and properties of polymeric materials. Under his guidance, developments in measurement techniques such as the application of laser-Doppler velocimetry to polymer melts and the Münstedt tensile rheometer were carried out. He is author of over 200 publications in scientific journals, concerning various fields of polymers.
