Our Team

Staff & Students
Robert Asarnow, PhD

Dr. Asarnow is the director of this laboratory. He is the Della Martin Professor of Psychiatry in the UCLA Department of Psychiatry and Biobehavioral Sciences and also a Professor in the UCLA Department of Psychology. He is a neuropsychologist with extensive experience in the neuropsychological evaluation of children and adolescents with TBI and in the use of brain imaging and electrophysiology in clinical research. Dr. Asarnow and his students and colleagues have conducted one of the major studies of the cognitive and psychological outcomes following mild traumatic brain injury in children and one of the largest controlled studies of cognitive training in children with brain injuries. By enhancing our understanding of the likely range of outcomes after a child incurs a mild traumatic brain injury these studies have provided information that help parents develop plans to maximize the recovery of their children. He is the principal investigator of two studies of pediatric traumatic brain injuries funded by the National Institute of Health that are currently being conducted in the laboratory. In addition to his research Dr. Asarnow also sees patients with traumatic brain injuries and their families clinically.

He has a particular interest in investigating the neural correlates of cognitive control function, both in various patient groups, as well as in healthy individuals. At UCLA, his main responsibility is related to working with functional MRI data from a longitudinal study of recovery after pediatric traumatic brain injury. Dr. Olsen is involved in research activities on traumatic brain injury both at UCLA and in Norway, and is passionate about facilitating international collaboration in order to improve the quality of scientific research and health care for this patient group.

Larissa Del Piero

Larissa Del Piero is a staff research associate on the RAPBI project and is a doctoral candidate in the Clinical Science area of the University of Southern California Psychology Ph.D. program. Larissa’s research explores the impact of significant stressors (e.g., violence exposure) on cognitive processes and emotion regulation. Her masters project examined the relationship between exposure to community violence, psychological distress, and academic performance during middle and high school. In 2010, she received a National Science Foundation Graduate Research Fellowship to study the relationship between violence exposure, cortisol reactivity, and performance on standardized tests of fluid intelligence. She is currently working on her dissertation, which uses functional magnetic resonance imaging and a novel experimental paradigm to explore cognitive control of emotions in youth who have been exposed to family violence. Larissa is hoping to extend this research in the future to examine cognitive and emotional consequences of significant medical stressors (e.g., traumatic brain injury) for children and families. Clinically, Larissa has an extensive background in neuropsychological assessment and is interested in integrating mindfulness and family systems approaches into the treatment of both pediatric and adult populations with cognitive difficulties.
