About

Alysson R. Muotri is a pioneering neurobiologist whose research lies at the intersection of stem cell biology, neurodevelopment, and bioengineering. His work has fundamentally reshaped our understanding of human brain evolution, neurological disorders, and the potential of regenerative medicine. Muotri is best known for using induced pluripotent stem cells (iPSCs) to model neurodevelopmental and neurodegenerative conditions, including autism, Rett syndrome, and Alzheimer’s disease, creating "brain-in-a-dish" platforms that recapitulate human neural development. His contributions extend to exploring the role of ancient viral DNA—such as endogenous retroviruses—in brain evolution and function, revealing how these genetic elements influence neuronal plasticity and disease. With over 20,000 citations, Muotri’s impact is profound; his 2013 study on human brain organoids has been cited more than 1,500 times. He has also pioneered non-genetic neuromodulation using graphene-based optoelectronic actuators, enabling precise control of neural activity without genetic alteration—a breakthrough for disease modeling and biohybrid robotics. A recipient of the NIH Director’s Pioneer Award and a member of the National Academy of Medicine, Muotri continues to push the boundaries of stem cell science and neuroengineering, inspiring a new generation of researchers to explore the frontiers of the human brain.
