Faculty & Staff

Diane Stadler GPHN Director

Program Director

Diane Stadler, PhD, RD, LD

Dr. Stadler received a BS in Special Studies with an emphasis in Genetics and Development from Davidson College, an MS in Nutrition Science from Virginia Tech, and a PhD in Human Nutrition from the University of Iowa. She completed a post-graduate fellowship at the Kennedy-Krieger Institute/Johns Hopkins Hospital and focused in nutritional interventions for children with developmental disabilities and/or gene disorders. She worked with dietetic interns at the University of Iowa and directed the Nutrition Science and the Coordinated Masters Programs at the University of Utah before joining the faculty at OHSU in 2000.

Dr. Stadler is an Assistant Professor of Medicine and Director of the Graduate Programs in Human Nutrition at OHSU.  Her clinical work and research has focused on dietary interventions for the treatment and prevention of disease including:

  • Nutritional rehabilitation of severely malnourished children in Zambia, Africa
  • Nutrition education and growth monitoring of infants and young children at risk for malnutrition in the rural mountainous region of eastern Honduras
  • Dietary treatment of children with rare genetic disorders
  • Use of extremely high fat ketogenic diets for children with severe, unresponsive seizure disorders
  • Comparing the health risks and benefits of very low-and high-complex carbohydrate diets for weight loss in obese adults
  • School-based interventions for diabetes prevention

Melanie Gillingham

Master's Program Director

Melanie Gillingham, PhD, RD

Dr. Melanie Gillingham is an Assistant Professor in the department of Molecular & Medical Genetics and the Graduate Programs in Human Nutrition at Oregon Health & Science University.  She received her BS in Nutrition from Texas Christian University, Ft. Worth, TX & her MS in Nutritional Sciences from University of Oklahoma, Oklahoma City, OK & completed her PhD at University of Wisconsin-Madison, Madison, WI.  Dr. Gillingham coordinates the Masters programs and maintains an active research laboratory.  Her research interests are on the nutritional treatment of inborn errors of metabolism and the effect of diet on fatty acid oxidation.  The mitochondrial fatty acid oxidation (FAO) pathway is critical for survival during periods of fasting and for the maintenance of normal body weight and insulin sensitivity.  The Gillingham Laboratory has been investigating the metabolic consequences of genetic disorders in the FAO pathway including inherited deficiency of very-long chain acyl CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl CoA dehydrogenase (LCHAD) and carnitine palmitoyltransferase type 1A (CPT1A) deficiencies.  FAO disorders are inherited in an autosomal recessive manner and collectively have an incidence of 1:9000 live births.  Infants with a FAO disorder typically present with hypoketotic hypoglycemia and Reye-like symptoms precipitated by fasting or illness.  The treatment for long-chain fatty acid oxidation disorders has been primarily with a modified diet including avoiding long periods of fasting, and frequent high carbohydrate meals.  We have been investigating alternative nutritional approaches including fish oil supplements, medium-chain triglyceride supplements prior to exercise, and high protein diet low-fat diets on the outcomes and complications of these disorders.  Dr. Gillingham is an active member of the Genetic Metabolic Dietitians International, the Society of Inherited Metabolic Disease, American Society of Nutrition and The Academy of Nutrition and Dietetics.

Dr. Hansen completed her BS in biochemistry and molecular biology from Liberty University in 2009. In 2013, she earned a PhD in Nutritional Sciences from Cornell University with concentrations in epidemiology and genomics. She went on to complete the OHSU dietetic internship in 2014. Her doctoral research focused on the interplay of genes, nutrition, and chronic disease, with a specific emphasis on associations between vitamin D status and adult lung function. Dr. Hansen has presented her research at the American Society for Nutrition and American Thoracic Society international scientific conferences and has authored or coauthored several peer-reviewed scientific manuscripts. Her continuing research interests include gene-diet interactions that influence health outcomes as well as dietary interventions to reduce chronic disease risk. Dr. Hansen has a strong interest in science communication and has written articles for the Cornell Chronicle and the American Society for Nutrition student blog.
