Research Interest

My research is at the intersection between psychology and neuroscience, I am interested in the properties of the saccadic system trying to establish a low level approach to study the underlying processes guiding eye movements in simple and complex visual scenes.

Main research interests and methods

- Spatial and temporal properties of visually guided saccadic eye-movements.
- Experimental cognitive psychology: Interactions between cognitive processes, visual perception, attention and working memory.
- Voluntary and automatic attentional guidance, covert and overt attention, motor programming.

- Eye tracking (Eyelink II, Eyelink 1000, Dual Purkinje Image Eye-tracker, Cambridge Research System).
- Transcranial Magnetic Stimulation (TMS).
- Psychophysics
