Yuval Nir studied in the interdisciplinary program at Tel-Aviv University (Israel) covering topics in computer science, cognitive science, biology and philosophy, and received his MSc degree in computer science.

He then obtained a PhD in neurobiology at the Weizmann Institute of Science (Israel) at the lab of Prof. Rafael Malach. His doctoral dissertation compared spontaneous and evoked activities in the human visual and auditory cortices using fMRI, as well as single-unit, LFP and ECoG recordings in collaboration with Prof. Itzhak Fried at UCLA.

Dr. Nir is currently a postdoctoral fellow working with Prof. Tononi.

His current research interests include:

Sleep and consciousness
Dreaming and the brain
Sleep processes related to plasticity and learning
Understanding functional networks through spontaneous brain activity
Similarities and differences between spontaneous and stimulus-evoked conditions
Neuronal oscillations in cortex and hippocampus
Signal propagation in different sleep and wake states
Disorders of consciousness
Neural processes underlying cognitive impairments upon sleep deprivation.

Dr. Nir's research has been supported in the past and present by the Fulbright Program, the European Molecular Biology Organization (EMBO), the Human Frontier Science Program (HFSP), and the Brainpower for Israel Fund.
