Human intracranial electrophysiology

My present research explores the effects of electrical stimulation in the living human brain. I try to understand how intracranial brain stimulation affects cognition and emotion, and how this knowledge can be harnessed to help create better implanted brain stimulation devices to treat neuropsychiatric conditions.

About My Research

Meditation & Mindfulness

How does the human brain implement a mental skill as complex as meditation? How does long-term meditation practice, in turn, affect brain structure and function? I've studied meditation using a mix of cognitive testing, functional and anatomical MRI, and quantitative meta-analysis of neuroimaging data. I'm also very interested in the potential application of meditation in medical settings, and the associated hype and ethical dilemmas.

Mind-Wandering & Creativity

Why does our mind wander so much of the time? How does mind-wandering help us create our sense of self and what connection does it have to creativity? My research has approached questions of this kind with a strong emphasis on the neural basis of mind-wandering and the role played by executive brain regions. This work also resulted in the first scientific volume dedicated entirely to mind-wandering and related forms of thought, which I co-edited with Kalina Christoff, The Oxford Handbook of Spontaneous Thought.

Whale and Dolphin Brain Evolution

Whales and dolphins (cetaceans) have the largest brains that ever evolved, exceeding even humans. And they are second only to humans in terms of their complex social lives. Before entering the research world I worked doing field research on humpback whales and have been fascinated with the social lives and big brains of cetaceans ever since. This work culminated in a major paper linking cetacean social behavior to brain size. I hope to focus more of my energy on research into brain evolution and the functionality of large brains in the future.
