Research projects






ERC Starting Grant project MATHANA


The project aims to develop neural population models describing phenomena observed in general anaesthesia.




Mutual synchronization in multivariate biomedical time series


This part of my work deals with synchronization of measured neural activity data mostly obtained during cognitive experiments or in motor tasks for monkeys. The data types are event-related potentials and fields (ERP/ERF), evoked potentials and Local Field Potentials. The focus of the work is the development of numerical algorithms, which detect mutual synchronization and mutual phase synchronization in single data sets. Since the neural activity is highly non-statationary in time, the methods extract an instantaneous degree of synchronization.




Modeling of neuronal network activity subject to delay and noise


This part of my work deals with continuous neuronal networks, which are extended in the spatial domain. The theoretical studies investigate and the spatio-temporal activity and networks with respect to effects of propagation delay, feedback delay and random fluctuations (noise). The investigated models consider excitatory and inhibitory neurons, excitatory and inhibitory synapses and various types of spatial connectivities.




Neural models of general anaesthesia


This work aims to model neural activity during general anaesthesia in order to explain the significant EEG signals observed in experiments. The underlying model considers excitatory and inhibitory neurons, excitatory and inhibitory synapses and various types of spatial connectivities and finite axonal conduction speed.




Effect of additive noise on nonlinear systems


The work performs a centre manifold analysis in the presence of random fluctuations with and without delays demonstrating a shift of stability subjected to additive noise.
