Matthew Walker earned his PhD in neurophysiology from the Medical Research Council in London, UK, and subsequently became an Assistant Professor of Psychology at Harvard Medical School in 2004. He is currently Professor of Psychology and Neuroscience at the University of California, Berkeley, where he directs the Center for Human Sleep Science. Walker is the recipient of funding awards from the National Science Foundation and the National Institutes of Health, and in 2006, became a Kavli Fellow of the National Academy of Sciences. He investigates the role of sleep in human health and disease. He does so using brain imaging methods (MRI, PET scanning), high-density sleep EEG recordings, genomics, proteomics, autonomic physiology, and cognitive testing. Walker addresses issues of both wellness and disease. Disorders that he currently tackles include Alzheimer's disease, Parkinson's disease, cancer, depression, anxiety, insomnia, cardiovascular disease, drug abuse, obesity and diabetes. His Center's goal, unachievable as they may be: to understand everything about sleep's impact on the human being, from birth to death, in health and in sickness. Walker is the author of the International Bestseller, Why We Sleep. The book has been translated into over 40 different languages, and was listed as one of Bill Gates's top 5 favorite books of 2019. Walker has also given a main-stage TED talk, which has been viewed over 23 million times.
