Charina Ramirez, M.D. Professor School Medical School Department Pediatrics You have reached the Academic Profile. For more information on the doctor and patient care, please visit the clinical profile. Biography 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.
