Nancee is the chief dietitian for the UCLA Vatche and Tamar Manoukian Division of Digestive Diseases. Given that the digestive tract is intimately involved with many of the processes which govern nutritional health, she was recruited in 2012 to help develop a comprehensive GI nutrition program to enhance patient care with specific nutritional issues and to provide on-going nutritional education to UCLA GI fellows, gastroenterologists and other healthcare professionals. The GI nutrition program is now an integral part of, and a catalyst for, the division's Integrative Digestive Health and Wellness Program.

In addition to her chief role, Nancee continues to provide direct patient interaction during individual nutrition counseling sessions for diagnoses such as irritable bowel syndrome, inflammatory bowel disease, celiac disease, short bowel syndrome and idiopathic or functional bowel. She also leads the functional gastrointestinal disorders workgroup for the Academy of Nutrition and Dietetics Dietitians in Gastrointestinal Disorders (DIGID) Practice Group. Nancee's expertise draws invitations to speak on nutrition and digestive disorders at national conferences. Her current research includes the reintroduction phase of the low FODMAP diet with Lin Chang, MD, co-director of the UCLA G. Oppenheimer Center for Neurobiology of Stress and Resilience, and she was a former reviewer for the American Gastroenterological Association patient initiatives for short bowel syndrome and the low FODMAP diet in 2016.

Nancee graduated from California State University, Los Angeles, where she earned her masters of science in nutrition. She completed her dietetic internship at the Cedars-Sinai Medical Center and at the University of California, Los Angeles, where she was mentored by Dr. Lin Chang.
