EU project Diaspora


DIASPORA project

DIASPORA is a four-year collaboration between RWTH Aachen University and IBM Research – Zurich within the "industry-academia partnerships and pathways" program (IAPP), funded by the European Commission.

Industry-Academia Partnerships & Pathway

The Industry-Academia Partnerships & Pathways (IAPP) is a Marie Curie Action that seeks to enhance cooperation between public research organizations and private commercial enterprises based on longer-term cooperation program to increase knowledge sharing and mutual understanding in both industrial and academic sectors. Participants in an IAPP are one or more research organizations (e.g. universities) and one or more commercial enterprises that propose a joint research project within which transfer of knowledge takes place. This transfer of knowledge is reached primarily through staff secondments (staff exchanges).


The main objectives of Diaspora are so-called phase-change materials, which are currently a promising class of materials to be used as the next generation of memory; we aim to understand the underlying physics of the remarkable properties of these materials.
