Pediatric Infectious Disease Fellow, PGY-4

Marielys Collazo-Roman, MD, MSc, is a pediatric infectious disease fellow at the University of North Carolina (ºÚÁÏÍø). She earned her medical degree from Ponce Health Sciences University and completed her pediatric residency training at St. Louis University-SSM Health. Additionally, Dr. Collazo-Roman holds a Master of Science in Epidemiology and Biostatistics from the University of Puerto Rico Medical Sciences Campus.
Her research has explored the association between carotenoid intake and the incidence of breast cancer in premenopausal and postmenopausal women. Her passion for pediatric infectious disease research is driven by a deep commitment to addressing health inequities affecting some of the world’s most vulnerable populations—children.
Dr. Collazo-Roman has previously conducted research on pediatric cancer, including a population-based analysis of cancer incidence in children with Down syndrome. She has also collaborated with Dr. Kanetsky on studying the association between MC1R mutations and phenotypes with skin cancer risk.
Currently, she is working with Dr. Lakshmanane, Dr. De Silva and Dr. Becker-Dreps, and her research focuses on dengue, a neglected infectious disease with significant morbidity in children. She investigates both the natural immune response and the vaccine-induced immune response—an area of ongoing debate within the scientific and medical communities.
Dr. Collazo-Roman aspires to become a physician-scientist specializing in virology and vaccinology.
