About Kate E. Wallis, MD, MPH
Kate E. Wallis, MD, MPH, is a board-certified developmental & behavioral pediatrician who takes care of children in the Division of Developmental and Behavioral Pediatrics. She specializes in treating children with autism spectrum disorder (ASD) and other developmental conditions. Her research is focused on improving care for children with potential developmental delays or diagnosed disabilities. She serves as Assistant Program Director for the Fellowship in Developmental and Behavioral Pediatrics at CHOP.
Dr. Wallis developed her interest in working with children when she was still in high school. At the time, she worked at a camp for children with developmental disabilities. “I loved meeting the campers and their families, learning about their conditions, and seeing the progress they made each summer during their time at camp. I knew then that I wanted to work with children with developmental disabilities,” she says.
As she pursued her education, she became interested in the field of developmental-behavioral pediatrics. “I love that my field lets me think about what makes kids kids: how they learn, develop, play, and interact with others. Now, I get to play with really cool kids every day at work!” Dr. Wallis says.
She says she feels a particular connection to kids who have autism. “Families of these kids are often seeking answers and help, and I feel like I have something unique to offer them. I may not always have all of the answers to every question I am asked, but I aim to take every question and concern seriously to try to help families gain the understanding that they seek. Families should know that I go home and think about my patients, worry about them, and hope that the care that I provide them helps in some small way.”
Dr. Wallis is optimistic about how care for children on the spectrum is evolving. “We are learning more about autism every day—not as quickly as some families would like—but we are constantly making progress in our understanding of ways to improve care,” she says. “I am excited to see how the field changes, as we develop new strategies to help children thrive.”
Education and experience
Dr. Wallis earned a Master’s in Public Health and her medical degree from SUNY Stony Brook University School of Medicine in Stony Brook, New York. She continued her training with a residency in pediatrics at New York University School of Medicine, New York; and fellowships in Developmental and Behavioral Pediatrics and Leadership Education in Neurodevelopmental Disabilities (LEND), both at Children’s Hospital of Philadelphia.
In addition to her clinical work, Dr. Wallis is an assistant professor at the Perelman School of Medicine at the University of Pennsylvania in Philadelphia, and as faculty in the CHOP Policy Lab. She has published frequently, primarily on the topics of autism and developmental delays.
Research
Dr. Wallis’ research focuses on how we can improve the care of autistic youth in primary care settings: from the time that developmental delays are first identified, to diagnosis, and through adolescence to young adulthood, to make sure we are supporting all of their medical and mental health needs. “Pediatricians care for most children and youth on the autism spectrum, but they need support to address all of the medical and mental health needs that may be more common among autistic youth compared to their typically developing peers,” she says. “My research focuses on finding ways to improve the identification of and care for autistic youth to more equitably help them receive the care they need when they need it.”
