Research interests

My research aims at understanding the mechanisms underlying visual perception and recognition of complex visual stimuli such as scenes, faces or objects. I am interested in how we use low-level characteristics of sensory inputs to efficently achieve recognition and how this may be modulated by prior knowledge and expectations about the visual environement. To study these questions, I use complementary techniques such as psychophysics, eye-tracking or neuroimaging.

Main research Axes :

• Influence of predictive processes on subjective visual perception - ANR EXPER 2023-2027
• Use of eye movements to investigate cognitive (dys)functoning
  Collaborators : Nathalie Guyader (GipsaLab), Anne guérin (GipsaLab), Michel Dojat (GIN), Carole Peyrin (LPNC)
• Mapping and functional role of visual subcortical structures
  Collaborators : Christa Müller Axt (MPI-CBS), Katharina von Kriegstein (TU-Dresden)
• Mechanisms of scene categorization
  Collaborators : Carole Peyrin (LPNC), Alan Chauvin (LPNC)
