Prof. Dr. Ir. Clemens Mensink is the head of the environmental modeling unit at VITO in Belgium. The unit employs more than 100 researchers, ICT professionals and technicians. They develop, improve and implement methodologies and computer models to estimate the impact of human activities on air, water and soil quality in a spatial context.  Clemens received his Ph.D. (1992) and a postgraduate degree (1988) in fluid dynamics from the Von Karman Institute in Belgium. He studied fluid mechanics, numerical mathematics and chemical engineering, and received his M.Sc. (1987) in mechanical engineering from the University of Twente in the Netherlands. In 1998, he received the ENERO prize. Clemens is currently president of the International Technical Meeting on Air Pollution Modeling and its Applications. He is an expert in air pollution modeling and the author of more than 80 peer-reviewed publications in international journals.  He is lecturing Air Pollution Modeling at Ghent University (postgraduate studies in Weather and Climate Modeling) and University of Hasselt.Dr. Volker Matthias is head of the chemistry transport modelling department at Helmholtz-Zentrum Hereon, Germany. The department develops and applies emission models as well as regional and city scale atmospheric model systems to study matter transport and air pollution in coastal areas. Volker studied physics at the University of Hamburg and did his PhD in Meteorology at the Max-Planck-Institute for Meteorology in Hamburg in 2000. Since 2003 he is employed at Helmholtz-Zentrum Hereon. His research focus is on emissions, transport and transformation of pollutants in the atmosphere. Since several years, ship emissions are an important aspect of his work. He is author of more than 80 peer reviewed publications. He is teaching Atmospheric Chemistry at the University of Hamburg as well as Transport of Matter in the Environment and Model Systems in Global Change Research at Leuphana University Lüneburg. He has guided several PhD, Master and Bachelor students.
