As a neuropsychologist at Kennedy Krieger Institute and Assistant Professor at johns Hopkins School of Medicine, Dr. Peterson works primarily with oncology and congenital/genetic populations in a clinical and research manner. 

Research Summary:

Recognition of the neuropsychological effects of childhood cancers and their treatments has led to significant changes in treatment regimens and follow-up care for survivors over the past three decades. While most children treated for cancer will achieve long-term survival, survivorship comes with a cost as they are at risk for long-term neurocognitive impairments, educational difficulties, social problems, and psychological and medical disabilities. Limited functional independence in this population results in notable cost and burden for families and society, necessitating research to identify those most at risk and alleviate these sequelae.


Dr. Peterson’s long-term research goals are to contribute to our understanding of the role of disease, treatment, and demographic variables on cancer outcomes in order to improve the quality of life for pediatric cancer patients and survivors. Her research to date has documented the neurocognitive and psychological difficulties pediatric oncology survivors experience as well as predictors, risk factors, and neuroprotective factors that impact their neuropsychological functioning. 


Dr. Peterson’s previous research studies have looked at disease and treatment related variables, such as neuropsychological late effects and white matter correlates in children treated for a brain tumor without radiation therapy, cognitive functioning following proton beam radiation therapy versus traditional radiation therapies, and experimental chemotherapy agents such as MEK-inhibitors on neuropsychological functioning. She has also investigated the role of cancer on the family system in brain tumor as well as leukemia and solid tumor populations. Understanding the role of these variables on long-term functioning will enable clinicians and researchers to develop interventions to ameliorate these outcomes.
