  • Diabetes, Critical Care

Research Focus

Dr. Marcia Nahikian-Nelms’ research is driven from both her responsibilities in curricular teaching and clinical education. Her research goals are as follows:
  1. To provide synthesis and development of evidence based medical nutrition therapy to support clinical practice
  2. To assess the effectiveness of alternative teaching environments for use in dietetic education and higher education
  3. To provide clinical nutrition expertise for ongoing research projects within the OSU College of Medicine, the Wexner Medical Center, Nationwide Children’s Hospital, community partners and our graduate program.
Her current research focuses on developing pedagogy for clinical education with a primary objective to develop experiential education that will bridge classroom to practice. Dr. Nahikian-Nelms’ case study textbook (Medical Nutrition Therapy: A Case Study Approach) is now in its fifth edition. 
These cases develop a realistic medical record that allows the student to gain initial experience with clinical reasoning and application of their nutrition knowledge. Most recently her work has moved toward the use of simulation and interprofessional collaboration with other health science professions.

Dr. Nahikian-Nelms additional focus area is to provide synthesis and application of evidence based research for use within nutrition therapy practice. This work is demonstrated with the publication of her textbook – Nutrition Therapy and Pathophysiology and through her contributions to the Nutrition Care Manual published by The Academy of Nutrition and Dietetics. 
She works to provide clinical expertise for support of the mission of translational nutrition science from bench to bedside and into the community through her clinical time within Leadership Education in Neurodevelopmental Disabilities and the Division Gastroenterology, Hepatology and Nutrition.
