Dr. Andreas Reppas


Dr. Andreas Reppas research interests lie on the development and implementation of computational methods for the analysis of the dynamics of multiagent systems. He is mainly focus on the study of multi-cellular systems as distributed information processing entities which encode, store, and transmit information via their interconnected pathways. Such an approach can provide interesting insights on how the cells store information (i.e. having memory) and how much information a cell can transfer reliably to its interacting neighbors (i.e. the capacity of the communication channel).


Dr. Andreas Reppas holds a Ph.D in Multiscale Analysis of Network-based Epidemic Systems (12/2011) from the National Technical University of Athens where he worked under the Supervision of Prof. Constantinos Siettos. After obtaining his Ph.D he continued as a Postdoc researcher at Max-Planck Institute for Informatics in Saarbrücken where he worked in the Computational Analysis of disease spreading. He joined the group of “Multiscale Modeling of Multicellular Systems” in July 2013.
