    Collapse Overview
    Dr. Paula Aristizabal is a pediatric hematologist-oncologist at Rady Children's Hospital-San Diego and an Associate Professor of Pediatrics in the Division of Pediatric Hematology/Oncology at UC San Diego. She completed her fellowship in pediatric hematology and oncology at UC San Diego and a Master of Advanced Studies in Clinical Research at UC San Diego.

    Dr. Aristizabal research interests include ethics, patient-provider communication and global health, with a focus on discovering the causes of pediatric cancer disparities and developing strategies to improve outcomes in racial/ethnic minorities and underseved groups. Her work has focused on the barriers to participation in pediatric cancer clinical trials experienced by Hispanic children and how social determinants of health, such as race/ethnicity, socio-economic status, health literacy, language, and acculturation, affect outcomes in Hispanics. She has also conducted global health projects on implementation of health services for children with cancer in underserved areas in Latin America, including Mexico and Colombia, to improve access to care, cancer surveillance and registration, and cancer disparities globally.

    Dr. Aristizabal is the principal investigator of several clinical research studies focused on implementation science, qualitative research, mixed methods, bioethics and quality improvement. She mentors trainees and junior faculty in diverse quality improvement and research projects, including medical students in their ISP projects.
    She is a member of the UC San Diego Moores Cancer Center Population Sciences, Disparities and Community Engagement division, the San Diego Clinical and Translational Research Institute, and the UC San Diego Dissemination and Implementation Science Center.
    In her clinical work, Dr. Aristizabal specializes in the care of children with leukemia and lymphoma. She is the Division's Quality Improvement Lead and chair of the Quality Improvement Committee.
