CV Summary: 

Sumitash Jana is an Assistant Professor of Cognitive Neuroscience in the Cognitive Science programme in the Department of Humanities and Social Sciences, Indian Institute of Technology Delhi. He joined the department in September, 2021. His research interest lies in studying the brain mechanisms that mediate self-control, i.e. how we control our movements, thoughts, and actions.

Research Areas

His research broadly focuses on understanding the brain mechanism that mediate self-control. Self-control is our ability to focus on our tasks and goals despite environmental interruptions (e.g., choosing to keep reading despite notifications on your phone) but also flexibly change our goals when the need arises (e.g. choosing to pick up the phone when there is an important call). His research uses behavioral studies, brain imaging (e.g., electroencephalography) and brain stimulation (e.g., transcranial magnetic stimulation) methods to investigate self-control.

His current research goals include understanding the impact of mind-wandering and mediation on self-control in both healthy and clinical populations, and studying self-control in more-realistic scenarios using virtual reality.
