Tammy Bray, Ph.D.
Professor
Principal Investigator Linus Pauling Institute

Tammy's research interests are antioxidants and free radical metabolism in prevention of diabetes. The role of diets in gene expressions that influence the susceptibility to chronic diseases.

Michelle Bump, MS, RD, CSR, LD
OSUDI Clinical Coordinator

Michelle's professional career has included working as a clinical dietitian at Parkland Health and Hospital System in Dallas and as the Lead Dietitian for DaVita Healthcare Partners, a large, national chain of renal dialysis clinics, where she has been engaged in clinical nutrition management, quality planning, monitoring and management and other educational and clinical endeavors.

Mary Cluskey, Ph.D., RD
Associate Professor
Director of the Dietetics Internship

Mary's research interests are the behavior associated with making food choices including internal motivations, factors related to access, convenience and time, perceptions of health, dining location, culture and economics.

David Dallas, Ph.D.
Assistant Professor
Director of the Nutrition Undergraduate Program

David's research examines the digestion of human and dairy milk proteins and the release of bioactive peptides using in vivo infant and adult digestive samples. His group applies mass spectrometry-based peptidomics and proteomics and functional assays. In addition, he applies this knowledge to examine digestive deficiencies in premature infants.

Stephanie Grutzmacher, Ph.D.
Assistant Professor

Stephanie's work focuses on food security, nutrition literacy and the development and evaluation of family, school and community-based nutrition education programs for low-income populations.

Emily Ho, Ph.D.
Professor
 

Emily's research interests are in the area of antioxidants and gene expression and dietary chemoprevention strategies. She is currently interested in understanding the role of the antioxidant nutrients such as zinc in maintaining DNA integrity and cancer development.

Urszula T. Iwaniec, Ph.D.
Professor
Director of the Nutrition Graduate Program

Urszula's research foci include: 1) Neuroendocrine regulation of body weight and bone metabolism. 2) Nutrition as a factor in tumor metastasis to bone. 3) Regulation of stromal (stem) cell differentiation into bone cells and fat cells.

Jenny Jackson, Ph.D.,MS, RDN
Clinical Assistant Professor

Jenny’s current work focuses on experiential teaching and learning to help students engage with food and nutrition concepts via hands-on and service-based activities. Her research interests include community-based and epidemiological investigations focused on food security and the promotion of healthy eating and physical activity behaviors across the lifespan.

Donald B. Jump, Ph.D.
Professor
Principal Investigator-Linus Pauling Institute

Don's research investigates the molecular and metabolic basis of complications associated with obesity and diabetes. His current focus is on the role diet plays in the onset and progression of nonalcoholic fatty liver disease (NAFLD), a major global health problem.

Yumie Takata, Ph.D.
Assistant Professor

Yumie is a nutritional epidemiologist and her research focuses on the etiological roles of nutritional factors in cancer and chronic disease.

Maret Traber. Ph.D.
Professor
Principal Investigator-Linus Pauling Institute

Maret's research efforts are focused on the physiological properties of vitamin E, especially human vitamin E kinetics and the factors that modulate human vitamin E requirements, such as bioavailability, lipid peroxidation and metabolism.

Russell T. Turner, Ph.D.
Professor
Director of the Skeletal Biology Laboratory

Russell's research focuses on gravitational physiology, etiology and treatment of osteoporosis, osteoimmunology and renal osteodystrophy. He investigates how exercise, nutrition and life style interact to influence life-long skeletal health.

Siew Sun Wong, Ph.D.
Associate Professor
Extension Nutrition Specialist
Interim Endowed Director of Moore Family Center for Whole Grain Foods, Nutrition and Preventive Health

Siew Sun's research areas are obesity prevention and youth calcium and bone health. Her interests include innovative nutrition education, especially among low-income families, where she develops and evaluates education games.
