Welcome!

Since September 1st 2013, I am an associate professor at the University of Lorraine (http://www.univ-nancy2.fr/sciencescognitives/index.html) in the Neurosys team, at Loria (Laboratoire Lorrain de Recherche en Informatique et ses Applications).

In general, I am interested in understanding how intrinsic dynamics of single neurons impact neural network behaviors, bridging the gap between modeling scales being necessary to a better understanding of the neuronal/nervous system.






Current projects:
- Mathematical Modelling of Neural Oscillations in Hippocampal Memory Networks during Waking  and under General Anaesthesia
- Sleep/Wake mathematical modelling and extraction of electrophysiological markers of the epileptical hippocampus.

Main research topics:
- neuronal synchronization and oscillatory behaviors (application to anaesthesia, hippocampal system, olfactory system of insects)
- parameter estimation of neuronal models (more specifically conductance-based models) with stochastic optimization methods
- general anaesthesia
- memory formation and retrieval
