Andreas Spiegler is a postdoc at the Institut de Neurosciences des Systèmes (INS), Aix-Marseille Université (AMU), France, working in the Theoretical Neurosciences Group (TNG) with Prof. Viktor K. Jirsa since October 2011. His research currently focused on brain stimulation (tDCS) and the role of transmission delays among brain areas in the large-scale brain architecture. Since 2014, he is a fellow of the Human Brain Project, SP3: Theoretical and Mathematical Foundations of Neuroscience (European Union Seventh Framework Programme: FP7-ICT).

Selected publications:

The interest of his research lies on pattern formations in the brain, at different spatial and temporal scales, such as under rest conditions and during stimulation. The main hypotheses are: (i) principles of pattern formation can be determined; and (ii) mechanistic descriptions of (functional and behavioral) phenomena through such principles reveal strategies and concepts helping to support life, in particular under pathological conditions (e.g., using stimulation techniques). In this context, mathematical and computational modeling plays an important role, though challenged by finding an adequate scale of description of the myriads of interacting elements in the brain and the limitations of available measurement techniques. The role of network interactions (e.g., with transmission delays) in system states (e.g., synchrony) or in state-changes (e.g., criticality) and the use of each node’s repertoire (i.e., attractors) are key issues to tackle by using mathematical tools such as from bifurcation theory.

In 2011 Andreas Spiegler received his Ph.D. (Doktor-Ingenieur) from the Department of Computer Science and Automation, Technische Universität Ilmenau (TU Ilemnau), Germany with the work:

Spiegler A (2012) Dynamics of biologically informed neural mass models of the brain. Universitätsverlag Ilmenau. ISBN: 978-3-86360-024-2, URN: nbn:de:gbv:ilm1-2011000503.

The research was conducted at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI-CBS), Leipzig, Germany in the Research Group Cortical Networks and Cognitive Functions leaded by Dr. Thomas R. Knösche, and at the Institute of Biomedical Engineering and Informatics, TU Ilmenau, Germany under the supervision of Professor Jens Haueisen. The main collaborators for this work where Dr. Fatihcan M. Atay (Max Planck Institute for Mathematics in the Sciences, Leipzig, Germany), Dr. Stefan J. Kiebel (MPI-CBS, Leipzig, Germany), and Dr. Karin Schwab (Bernstein Group for Computational Neuroscience Jena, Institute of Medical Statistics, Computer Sciences and Documentation, Jena University Hospital, Friedrich Schiller University, Jena).

Andreas Spiegler received his M.Sc. degree (Diplom-Ingenieur) in Electrical Engineering and Information Technology at TU Ilmenau, Germany, where his work was focused on the development of methods for the quantification of synchronization processes during short-term memory
tasks with Prof. Günter Henning and Dr. Galina Ivanova (leader of The NeuroCybernetics Research Group at the Institute of Biomedical Engineering and Informatics). During that period, he also completed an internship at the Institute of Human-Computer Interfaces, Graz University of Technology (TU Graz), Austria, working with Prof. Gert Pfurtscheller, with the following publication:
