Just me playing around with my good old robot Psikharpax.

Background

  • I am currently a Post-Doc researcher at the Olivier Ly's Rhoban team (LaBRI, Univ. Bordeaux, France).
  • From 01/2014 to 12/2014 I was a Post-Doc researcher at the Pierre-Yves Oudeyer's FLOWERS team (INRIA Bordeaux, France) working on the Poppy project.
  • From 2010 to 2014 I was a Post-Doc researcher at the LPPA (Collège de France, Paris, FRANCE) working in Jacques Droulez's Probabilistic Approach and Active Perception group.
  • From 2006 to 2010 I did my PhD Thesis at ISIR (UPMC Paris 6, FRANCE) under the supervision of Jean-Arcady Meyer and funded by the company BVS.
  • I completed my Engineering School (french Grandes Écoles) at the ECE along with a Masters Degree at the UPMC University (Paris, FRANCE).

Here is a CV.

Research interests

I am interested in understanding the sensory-motor loop in animals (including humans) through computational modeling.
My approach thus combines Neurosciences, Cognitive Sciences, Computer Sciences and Robotics.

My current interests are:

Mocap data for a curved trajectory.

Modeling of human locomotion

(in collaboration with Prof. Alain Berthoz, LPPA, Collège de France, FRANCE)

We try to understand invariant features observed in human locomotion (planned trajectories, gaze behavior…).

By running experiments in humans with motion capture and eye tracking we explore the way some stereotypical behaviors are modified according to imposed conditions.

Value potentials obtained from standard method and ours for an inverted pendulum system.

Control and planning under uncertainty

(in collaboration with Dr. Jacques Droulez and Pierre Bessière, LPPA, Collège de France, FRANCE)

We develop a different approach in control and planning under uncertainty taking unto account a probabilistic view of distances.

This method appears to be very efficient from a computational point of view, which may unlock some previously inaccessible problems due to the curse of dimensionality.

Drawing of a primate brain representing major areas involved in saccades.

Modeling of the saccadic system

(in collaboration with Dr. Benoît Girard, ISIR, UPMC Paris 6, FRANCE)

We try to understand the circuitry of the saccadic system and in particular the role of the different loops through the Basal Ganglia in the selection of visual targets.

To do so, we implement neurocomputational models based on several hypotheses that we test on simulation (or on robots) in order to propose predictions useful to biologists (as we hope so).

Projects

  • I am currently involved in the Poppy project: Poppy
  • Past projects in which I was involved: RoboSoM (European project ICT-2009.2.1), ROMEO (French government), ROMEO 2 (French government), ICEA (European project IST 027819), BIOTACT (European project ICT-2007.8.3), INTERACT (ANR, French government).
