My research interests lie at the intersection of cognitive neuroscience, neuropsychology, and cognitive psychology, focusing on metacognition and memory. My main research focus is examining the neurobiology and neuropsychology of metacognition and memory in both healthy and diagnosed populations (e.g. obsessive-compulsive disorder, game addiction, epilepsy, and schizophrenia). I am using EEG and neuropsychological methods and techniques in my projects.
