Gerry Leisman is an Israeli neuroscientist educated in Europe and the United States in Medicine, Neuroscience, and Biomedical Engineering at Manchester University.

He additionally received a Ph.D. in Neuroscience and Biomedical Engineering from Union University, in 1979. He is currently a Full Professor and Research Fellow at the University of Haifa in Israel.

He concurrently is Professor of Restorative Neurology at the University of Medical Sciences in Havana, Cuba. He is Editor-in-Chief of the journal Brain, Body Cognition.

His scientific career has largely been involved since the early 1970s in the promotion of consciousness as a scientifically tractable problem, and has been particularly influential in arguing that a fundamental understanding of consciousness can be approached using the modern tools of neurobiology and understood by mechanisms of theoretical physics, having, together with Dr.Paul Koch, developed biomedical applications of continuum theory. He has also been influential in examining mechanisms of self-organizing systems in the brain and nervous system applied to cognitive functions exemplified by his work in movement-cognitive interaction, memory, kinesiology, optimization, consciousness, death, autism, and developmental disabilities. He has likewise applied optimization strategies to movement and gait, cognition, and coma recovery. It is in this context that he was one of the first to identify functional disconnectivities in the brain and nervous system.

He was elected Fellow of the Association for Psychological Science in 1990, a Senior Member of the Engineering in Medicine and Biology Society of in IEEE in 1986, and a Life Fellow of the International Association of Functional Neurology and Rehabilitation in 2010, having received its Lifetime Achievement Award in 2011. He has served as a consultant to the US National Sciences Foundation.

He is the co-author of the text with Dr. Robert Melillo on Neurodevelopmental Disorders from an Evolutionary Perspective, with Dr. Joav Merrick on Clinical Aspects of Consciousness, and on Neuroplasticity. He has published hundreds of papers in the Neurosciences, Cognitive Science, Biomedical Engineering, and in the Systems Sciences literature.
