YERUN RMA 2018 – Meet Cristina González

From University Pompeu Fabra –> To University of Ulm

From June 25 to July 6, I worked in the faculty of Engineering, Computer Science and Psychology at Ulm University, in Germany.  I carried out my research activities in the Institute of Neural Information Processing under the supervision of Prof. Dr. Dr. Daniel Braun. We jointly worked in the characterisation of complex dynamical systems. The objective of the research mobility was to analyse the signals that I study in my PhD with techniques contributed by the host institution in Ulm. In particular, we applied complexity measures to EEG signals from epilepsy patients.   The joint interdisciplinary approach that arise from the synergy of both groups can lead to a better insight into dynamics derived from complex physiological systems such as the brain.

The aim of this study was to try to localise the seizure onset zone, the brain region from which clinical seizures are generated and thus help to improve the evaluation of epilepsy patients prior to surgery.  We have to take into account that we are dealing with methods that imply a big computational effort and big amounts of data, so we were only able to extract some preliminary results. These results are quite promising, as they are consistent with other results carried out prior to the research visit. These results are seed to run more experiments concerning complexity measures that imply a longer cooperation between both groups. We are still working on these methods and collaborating remotely, we are optimistic and hope that these results will end up in a long-term collaboration and/or jointly publication about this topic.

The YERUN RMA are a very good initiative to promote multi-disciplinary research accross the YERUN network.

Cristina González was awarded one of the 26 Research Mobility Awards of the 1st call for applications that YERUN offered in 2018.
