UC Berkeley Center for Human Science

Dr. Walker is the founder and director of UC Berkeley’s Center for Human Sleep Science.

The center's goal: to understand everything they can about sleep's impact on the human being, from birth to death, in health and in sickness.

Towards that end, the center explores the role of sleep in human health and disease using brain imaging methods (MRI, PET scanning), high-density sleep EEG recordings, genomics, proteomics, autonomic physiology, and cognitive testing.

Research covers: Alzheimer's disease, Parkinson's disease, cancer, depression, anxiety, insomnia, cardiovascular disease, drug abuse, obesity and diabetes.

Recognition

In 2006, he became a Kavli Fellow of the National Academy of Sciences. Dr. Walker is the recipient of funding awards from both the National Science Foundation and the National Institutes of Health.

Dr. Ram Gurumoorthy is on the founding research team at StimScience that published the study validating Somnee’s technology. Before StimScience, he was the Chief Science & Technology Officer and Principal Investigator of NeuroFocus Inc. (acquired by Nielsen Consumer Research). There, he directed a global team of Neuroscientists, Neurophysiologists, Signal Processing Experts, Algorithm Developers, and Product Engineers.

Neurofocus used proprietary brain state measurements to understand consumers' responses (emotion, memory and attention) to products, advertising, package/shopping experiences, and entertainment. Nielsen now uses this pioneering neuroscientific technology to measure consumer attention, engagement, and memory retention.
