Welcome !

   My name is Adrien Wohrer. I am a researcher in computational neuroscience, which is the study and formalization of the computations at work in the brain. Most of my research so far has been dedicated to studying the neural basis of perception, both in the visual and tactile systems. My approach to these problems involves tools such as statistical learning, point processes, signal processing and information theory.
   I am currently a post-doctoral fellow at the Group for Neural Theory of the Ecole Normale Supérieure, in Paris. I work with Christian Machens on the subject of population coding in cortical somatosensory areas. The main goal of this work is to understand how many neurons contribute to the percept experienced during a tactile stimulation, and what is the typical time-scale of this percept. I am also interested in neural coding in the early visual pathways, and how it correlates with psychophysics.


Short Bio

   You can find a more detailed C.V. here. In short:
  • I have an Engineering Degree from Ecole Polytechnique (obtained june 2003), and a Masters Degree in mathematics, vision and learning (MVA) from ENS Cachan (obtained june 2004).

  • I obtained my Ph.D. in march 2008 in the Odyssée Team (biological and computer vision, INRIA Sophia-Antipolis) on the modelling and implementation of a large-scale retina simulation software, under the direction of Pierre Kornprobst.

  • I taught applied mathematics (image processing, probabilities, geometric modelling) for three years at the Université de Nice - Sophia-Antipolis, in the scope of my thesis grant.
