Dr. Renske Lok is a postdoctoral fellow in the Psychiatry and Behavioral Sciences Department at Stanford University. She earned her doctoral degree from the University of Groningen in the Netherlands, where her research focused on the impact of light on human alertness, thermoregulation, and sleep. In her postdoctoral fellowship at Stanford, Lok delved into the relationship between light, timing of rest-activity patterns, and mental disorders. Her work also explored the influence of timed light exposure on alertness and cognition, employing diverse methodologies such as in-laboratory studies, field research, big data, and machine learning techniques.
