Consciouness; altered states of consciousness; sleep; dreaming; anesthesia; evolutionary psychology

My research mainly focuses on the simulation theories of the evolutionary function
of dreaming (the threat simulation and social simulation theories), and on understanding the neural mechanisms of conscious experiences
in general, and dreaming in particular.

Consciousness research, Altered states of consciousness, Neural correlates of Consciousness, Sleep and Dreaming, Anesthesia, Evolutionary psychology

I regularly teach courses on sleep, dreaming and other altered states of consciusness, and on evolutionary psychology.
