Dr. Neul is a licensed clinical psychologist who specializes in psychosocial intervention for youth with serious health conditions and their families. Her research is clinical intervention based with a focus on health-related quality of life (HRQOL) and quality improvement regarding patient-centered care. In collaboration with clinical psychologist, Dr. Michelle Reising, Dr. Neul co-created the Behavioral Hematology-Oncology Program (BHOP), a program which focuses on providing evidence-based practices in the psychosocial assessment of youth diagnosed with cancer and hematological disorders and their families.

In collaboration with the Stem Cell Transplant Team, Dr. Neul developed the Pre-Transplant Psychosocial Screening Survey, which is administered to patients ages 13 years and older and parents of patients (all ages) to assess for transplant readiness as well as psychosocial strengths and needs to devise a transplant-related psychosocial support plan for patients and caregivers.

In collaboration with the Sickle Cell Disease Team, Drs. Neul and Reising are incorporating an evidence-based cognitive screening intervention developed by pediatric SCD expert, Dr. Allison King at Washington University in St. Louis School of Medicine, to aide in academic support planning and education of patients, families, and school personnel regarding the impact of Sickle Cell Disease on learning and to ensure appropriate supports are in place to optimize academic and psychosocial functioning. Dr. Neul's clinical intervention-based research and program development efforts strive to match psychosocial intervention and supports with patient and family needs to optimize psychological adjustment and health outcomes.
