Caroline Leaf, Ph.D., BSc

Caroline Leaf, Ph.D, BSc, is a communication pathologist and cognitive neuroscientist, specializing in cognitive and metacognitive neuropsychology. She received her masters and Ph.D. in communication pathology, as well as a BSc in logopaedics from the University of Cape Town and the University of Pretoria in South Africa.

During her years in clinical practice and her work with thousands of underprivileged teachers and students in her home country of South Africa and in the USA, she developed a theory about how we think, build memory, and learn (called the Geodesic Information Processing theory). The learning process has been turned into a tool for individuals with Traumatic Brain Injury (TBI), Chronic Traumatic Encephalopathy (CTE), learning disabilities (ADD, ADHD), autism, dementias and mental ill-health issues like anxiety and depression.

Leaf is author of Switch on Your Brain, Think Learn Succeed, Think and Eat Yourself Smart, and Cleaning Up Your Mental Mess. She teaches at academic, medical and neuroscience conferences, churches, and to various audiences around the world. Dr. Leaf is also involved in the global ECHO movement, which trains physicians worldwide on the mind-brain-body connection, mental health and how to avoid physician burnout.
