Research
Our lab is currently engaged in three major research projects
Eye-Hand Coordination
We study the cortical mechanisms for visually guided arm movements. This research explores how the brain coordinates visual information with motor commands to accurately guide hand movements in three-dimensional space.
Our research combines rigorous computational models, visual psychophysics, 3-D motion analysis, direct neurophysiological recordings, and brain imaging techniques to understand the neural pathways involved in this complex process.

3-D Gaze Control
We investigate the neural mechanisms that rotate the eyes and head toward visual targets in three-dimensional space. This research focuses on understanding how the brain calculates and executes precise movements to direct our gaze.
Using advanced recording techniques and computational modeling, we study the neural circuits in areas like the superior colliculus, frontal eye fields, and parietal cortex that contribute to this fundamental behavior.

Trans-saccadic Integration
We study how the brain pieces together perceptions across different gaze fixations. Despite making rapid eye movements (saccades) several times per second, we perceive a stable and continuous visual world.
Our research investigates the neural mechanisms that allow the brain to integrate visual information across saccades, maintain spatial memory, and update our internal representations of the visual environment.

Research Approach
To study these topics, we use rigorous computational models, visual psychophysics and 3-D motion analysis, direct neurophysiological recordings of brain activity, high resolution brain imaging (fMRI, MEG), Transcranial Magnetic Stimulation (TMS), and clinical patient studies.
I have found that the multi-disciplinary interplay between these approaches promotes an exciting, collaborative research environment. Moreover, this approach seems to be bringing us closer to our ultimate goal: to understand how the brain works.
