Funded by the VILLUM Foundation for the period 2017-2023, the Matter project is an integrated part of the Glass and Time center (http://glass.ruc.dk ) at Roskilde University’s Department of Science and Environment. Glass and Time is characterized by strong collaboration between experiment, simulation, and theory. The purpose of Matter is to understand the fundamental governing principles of structure and dynamics of liquids and solids, in particular to investigate and further develop the isomorph theory. We are looking for a talented Ph.D. student for an experimental project within Matter. The student, who will be trained in experimental work in the Glass and Time center, will be supervised by Prof. Kristine Niss or Assoc. Prof. Tina Hecksher, and co-supervised by Prof. Jeppe Dyre (the director of Matter).
