Kristina K. Hardy, Ph.D., is a pediatric neuropsychologist within the Division of Neuropsychology at Children’s National Hospital and an Associate Professor in the Departments of Psychiatry & Behavioral Sciences and Pediatrics at the George Washington University School of Medicine. Dr. Hardy has expertise in developmental and acquired difficulties with attention, learning, and executive functioning. She provides clinical services, including evaluation and therapy, to children and adolescents with a broad range of mental and medical health issues, including those with ADHD, pediatric cancer, and neurofibromatosis, type 1. Her clinical research program is focused primarily on identifying factors associated with neurocognitive difficulties in survivors of pediatric cancer and children with neurofibromatosis, as well as developing and assessing interventions for these difficulties. She has a particular interest in evaluating the use of technology in mental health, including computerized assessment and cognitive training programs.

Dr. Hardy is also involved with clinical studies associated with the Children’s Oncology Group, in which she serves as a member of the Behavioral Science and Cancer Control steering committees. At Children's National, Dr. Hardy serves as the Director for the Neuropsychological and Psychosocial Evaluation Core of the Clinical Studies Resource within the Clinical and Translational Science Institute, and is actively involved in training graduate students, predoctoral interns, and postdoctoral fellows.

This faculty member (or a member of their immediate family) has a working relationship (i.e. consulting, research, and/or educational services) with the companies listed below. These relations have been reported to the health system leadership and, when appropriate, management plans are in place to address potential conflicts.
