Structure and Self-Organization of the Research Consortium

Organizational Structure of SFB 1120 Organizational Structure of SFB 1120

The Collaborative Research Center is structured as follows:

The Board has put in place an Executive Management consisting of a Managing Director and a Director of Finances. The management is responsible for all financial aspects of the SFB as well as for organizational matters, including the organization of workshops, summer schools, and other events; collaborations with other research institutions; and publications.

There is also an external Advisory Board that provides scientific direction according to the research program as outlined on the present website. It consists of mainly of representatives from industry, but also from other research institutions. The Advisory Board assists with defining research objectives and contributes scientific-technological assessments of the various approaches proposed by the SFB.

Organization of the Collaborative Research Center

Representation of the organizational structure and interaction between the project areas and the subprojects Representation of the organizational structure and interaction between the project areas and the subprojects

The Collaborative Research Center is divided into two project areas. Project Area A has a focus on melt processes at the microscopic level, while Project Area B focuses on the macroscopic level. Project Area A consists of 11 subprojects, while Project Area B has nine subprojects.

Three working groups are responsible for each project area; each working group consists of four subgroups.
