BIOGRAPHY

I am interested in modeling the feedback effect of spike-induced changes in ionic concentration (in particular extracellular potassium) on neuronal activity.

I did my PhD at the Inria Sophia Antipolis - Méditerranée Research Centre (France), with Mathieu Desroches and Martin Krupa. There, I investigated how mutations of the NaV1.1 sodium channel can lead to the initiation of either cortical spreading depression (CSD) or seizures, in a two-neuron conductance-based model with dynamic ion concentrations.

I am now working on incorporating potassium dynamics in a model based on the QIF neuron. We optimize this slow-fast model so that it captures the dynamics of a more detailed model while remaining much simpler, with a view to using it in a network.
