Executive control, performance monitoring, selective attention

I am investigating the neurocognitive basis of perceptual decision-making. More specifically, I am interested in examining the interplay between selective attention and performance monitoring (the cognitive process that allows us to evaluate our performance on a task). I am investigating how these cognitive processes enable perceptual decision-making when sensory inputs are ambiguous, as is often the case in the real world. My research takes advantage of electroencephalography, event-related brain potentials (ERPs) and brain stimulation techniques such as transcranial alternating current stimulation (tACS) to characterize the neural underpinnings of these cognitive processes.
