Expansion of the cluster

In January 2008 the PSSRC expanded and the group of Prof. Juergen Siepmann at the University of Lille joined the cluster. 

In August 2008 the group of João Pinto from the University of Lisbon joined the PSSRC at the 2nd PSSRC symposium. 

In September 2011 the groups of Johannes Khienast from the Technical University of Graz (Austria), Guy Van den Mooter from the University of Leuven (Belgium) and Stane Srcic from the University of Ljubljana (Slovenia) joined the cluster at the 5th PSSRC symposium.

Annual Symposia

Since its foundation one PSSRC symposium has taken place each year:

2007 Düsseldorf
2008 Ghent
2009 Copenhagen
2010 Cambridge
2011 Helsinki
2012 Lisbon
2013 Lille
2014 Lublijana
2015 Ghent
2016 Copenhagen

A particular aim of the symposium is to provide the younger members of the cluster with an opportunity to present their work. The symposium started as a closed meeting for cluster members only. The closed meeting consists of oral presentations of 10 minutes duration followed by 10 minutes of discussion of each paper. All sessions are chaired by PhD students and postdocs and the presentations are exclusively given by junior cluster members.

Following the success of the early symposia, in recent years the format of the meeting was extended to include an open day as well where the more senior cluster members present their research to the wider pharmaceutical community across academia and industry.

Research in the eight cluster centres is aiming to improve medicinal products by overcoming the current limitations on the molecular, particulate, process and product level through a better understanding of the fundamental science that is causing these limitations.

The research activities in the different cluster centres are focusing on improving process understanding through development of novel analytical solutions enabling efficient process monitoring and control solutions, and further, on modelling solutions in these environments.

The major research theme in the cluster is focusing on the understanding of the science behind common pharmaceutical processing operations from both an applied and a fundamental perspective. The development of different analytical techniques with a special emphasis on spectroscopic techniques is an essential prerequisite for increased process understanding.

The PSSRC cluster centers have available all critical unit operations of pharmaceutical relevance for joint projects and for industrial co-operation projects. PSSRC is the ideal partner for support in analytical process research and related intellectual property issues.

The following section of the website gives an overview of the different areas of research in the PSSRC.
