Prof. Dr. Walter Richtering

Physikalische Chemie
Forschungsinteresse

The research of W. Richtering is concerned with experimental physical chemistry of soft matter. Structure and dynamics of macromolecular and colloidal systems are studied in a broad range of length and time scales. We investigate various systems including, e.g., microgels, nanoparticles, bio-colloids, hydrogels, polyelectrolytes, vesicles and emulsions.

Various experimental techniques are employed with a particular focus on scattering, i.e., light Scattering: static, dynamic and 3D-cross-correlation as well as Small Angle X-ray & Neutron Scattering, SAXS, SANS.

Curriculum Vitae

Walter Richtering studied chemistry at the universities of Bochum and Freiburg and obtained his PhD with Prof. Burchard at the University of Freiburg. Afterwards he joined the University of Massachusetts as Feodor-Lynen Fellow of the Alexander von Humboldt-Foundation. He was appointed as Professor for Physical Chemistry at Kiel University in 2000 and to the chair of Physical Chemistry at RWTH Aachen University in 2003. In the same year he received the Raphael-Eduard-Liesegang award. In 2016 he joined DWI as an Associated Scientist.
