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 are 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.

Kendra Spears, M.Ed., CALT


Kendra Spears is currently a Dyslexia Interventionist for Dallas ISD. She has worked in education for the past 10 years. In 2022, she graduated from SMU with a Master of Education and Learning Therapy Specialization. Her Bachelor of Science in Elementary Education is from Oklahoma State University. 

Kendra struggled as a student and was diagnosed with her own learning difference in first grade. Throughout her education, her grades did not reflect her capabilities. Pursuing higher education always seemed out of her reach. With the help of some amazing teachers and professors, she found her passion in working with students who also had learning differences. Kendra’s mission is to help struggling readers become proficient readers, improve self-esteem, and become academically successful. She believes raising awareness and advocating for all children and adults with dyslexia is important for their success. She is excited to be working with IDA to continue educating parents and teachers to provide them with tools and resources to help those with dyslexia succeed. 


Associate Board 

Gabriella Collins

Gabriella Collins is currently an honors student at Abilene Christian University studying to obtain a Bachelor of Fine Arts in Musical Theatre.  She is also a member of the Big Purple Marching and Concert Bands playing the flute and piccolo.  She is a native of Arkansas and is comfortably becoming a proud Texan. Gabriella was diagnosed with dyslexia at the age of 11. She then completed a four-year Orton-Gillingham program which changed her life and set her on the path to academic success. 

As a result of the struggles she experienced in her early years, she became a fierce advocate and volunteer for dyslexia education and awareness. She is the founder and president of the dyslexia club at her high school and used that as a stepping stone to start her nonprofit Why Dyslexia Matters.  Gabriella has created a phone app, Instagram / Facebook page, and website to share interviews with dyslexia specialists, virtual story times, and the warning signs of dyslexia. She works to connect with students, teachers, parents, and community members by sharing her personal story.  She has created a phonetic alphabet musical theatre experience designed to help teach children about dyslexia and help dyslexic kids embrace it as their superpower.

When Gabriella is not advocating for dyslexia, she can be found dancing, singing and acting on stage.  She loves playing the violin and kazoo, listening to vinyls of Elvis, Elton John, and the Beatles and rewatching episodes of Friends.  On a typical day Gabriella can be found hanging out with her rescue standard poodle Amalia and sharing her love for her Greek heritage.

Aman Yarlagadda

Aman Yarlagadda is a high school student at Newman Smith High School in Carrollton Farmers-Branch Independent School District. He is quite interested in scientific research, conducting projects ranging from the use of Artificial Intelligence for pancreatic tumor identification to the synthesis of nanoparticles for chemiluminescence in bioimaging contexts. His passion for scientific research led him to the International Dyslexia Association, discovering the organization through a paper published by the National Institute of Health. 

His passion for dyslexia stems from his interest in the human brain. The sheer complexity of the organ, from its intricate neuronal wiring to its puzzling efficiency in long-scale communication, leaves much to be discovered by research scientists across the globe. He believes that the collaboration of scientists from many different disciplines is the key to unlocking the mysteries of the brain. Similarly, raising awareness about dyslexia and other neurological conditions will help foster a global environment that provides access to tools and resources for those who need them. 

In his free time, Aman enjoys playing the alto saxophone and watching his hometown sports teams. In particular, you can find him watching the Dallas Cowboys every Sunday (which usually doesn’t bode well for his sanity levels). Aman is excited to be a part of the Dallas IDA Associate Board and looks forward to helping make a difference.
