Institute for Systems, Informatics and Safety (ISIS) (JRC-ISPRA)

 

The Institute for Systems, Informatics and Safety (ISIS) forms part of the European Commission's Joint Research Centre whose mission is to provide customer-driven scientific and technical support for the conception, development, implementation, and monitoring EU policies. In the implementation of its mission ISIS concentrates on the assessment of risk in complex systems. It has developed expertise in aerosol physics, fluid dynamics, studies of complex systems, and various safety aspects. It has an extensive network of powerful workstations (Digital alphas and SUN Ultras) and it will be upgrading its old Cray to a Cray SVI: the primary justification for the upgrade is its use for atmospheric applications (vapour and aerosol transport in the atmosphere and in cities). ISIS is committed to the implementation of a quality system based on the international standards of the ISO-9000 platform.

Dr. Yannis Drossinos (Ph.D. in Chemical Physics, Harvard University, 1989) has worked on numerous aspects of nucleation theory, including the use renormalization-group techniques to the calculation of the nucleation rate close to the critical point. His current interests include both fundamental studies of nucleation and of the dynamics of non-linear systems, and engineering applications of heat and mass transport (either via a continuum formulation or Monte-Carlo simulations) in laminar and turbulent flow.
