Vaidehi Natu, Ph.D.


Dr. Vaidehi Natu is a Research Scientist at Stanford University. She received her doctoral degree in Cognition and Neuroscience from University of Texas at Dallas and then pursued her post-doctoral work from Stanford University and University of Texas, Southwestern Medical Center. Vaidehi is a developmental neuroscientist and has over 15 years of experience in scientific research and has published in several high impact journals including Science, Nature, and PNAS. Her research answers questions about how the human brain matures from infancy to adulthood, as it acquires new skills and behaviors such as learning to recognize objects, reading books, and communicating in a social environment. Her work shows that the brain achieves these complex tasks by growing new tissue structures, forming robust neural fiber connections, fine-tuning brain activity, and learning from its social environment. Vaidehi has extensive experience in communicating scientific research, and innovating novel methodologies in developmental neuroscience.

Vaidehi’s passion for dyslexia comes from her experience as a neuroscientist. The human brain undergoes several developmental changes in the primary years of life. It is plastic and can mold itself from early social and learning experiences. There are specific regions in the brain that process words and characters. In a typical developmental trajectory, as a child learns to read and write, these regions grow, become more active, and are well tuned to focus on words and characters. These developmental changes are highly significant in a child’s life and have long-term consequences for a successful life in adulthood. Hence, early intervention and diagnosis of dyslexia is critical. As a Dallas IDA board member, Vaidehi’s goal is providing scientific education and awareness of the importance of early dyslexia identification. She plans to work with IDA’s fundraising and training programs to achieve these goals. 

Vaidehi enjoys traveling, gardening, practicing yoga, and spending time with her husband, daughter, and her pup. Vaidehi is also the author and illustrator of a children’s picture book titled: “Once upon an idea”. Dr. Natu joined the board of the Dallas IDA in 2020 and is looking forward to working with a wonderful group of passionate individuals to spark the change.
