Dr. Charina Ramirez received her medical degree from UT Medical Branch in Galveston. She completed her internship and residency training in pediatrics at UT Southwestern/Children’s Medical Center. Subsequently Dr. Ramirez completed her fellowship in pediatric gastroenterology, hepatology and nutrition at UT Southwestern.
During her fellowships, she served as a research fellow in lipid metabolism under the mentorship of Drs. John Dietschy and Stephen Turley. Her research interests have involved cholesterol transport in the murine models of Niemann-Pick Type C disease and Lysosomal Acid Lipase Deficiency. Her current research project is evaluating the effects of a low carbohydrate diet in pediatric patients with metabolic syndrome and non-alcoholic fatty liver disease.
