Tammy Bray, Ph.D.
Professor
Principal Investigator Linus Pauling Institute
Tammy's research interests are evaluation of alternative protein sources, such as ocean-based underutilized discarded fish (by-catch), as a feasible, environmentally sustainable protein supplement to combat childhood malnutrition globally; antioxidants and free radical metabolism in prevention of diabetes; and the role of diets in gene expressions that influence the susceptibility to chronic diseases.
Michelle Bump, MS, RD
OSUDI Clinical Coordinator,
Director of Didactic Program in Dietetics
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
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.
Associate Professor
Director of the Nutrition Graduate 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.
Associate 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.
Neilann Horner, Ph.D., MPH, RD
Clinical Associate Professor
Director of the Nutrition Undergraduate Program
Neil’s work aims to ensure that evidence-based practitioners are in the field to provide medical nutrition therapy, and that those who may benefit are able to access nutrition services. Her research at OSU has focused on clinical nutrition service efficacy and outcomes.
Urszula T. Iwaniec, Ph.D.
Professor
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 Associate Professor
Director of Dietetic Internship Programs
Jenny’s 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. Her current projects address food insecurity among U.S. college students.
Josh Jorgensen, Ph.D., MPH
Instructor
Josh enjoys the challenge of getting non-nutrition majors interested in nutrition, while passing on knowledge of more in-depth content to the next generation of nutrition professionals. He is passionate about nutrition and loves learning more about the ever-changing field through questions from and conversations with students.
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.
Ingrid Skoog
Senior Instructor
Yumie Takata, Ph.D.
Associate Professor
Yumie is a nutritional epidemiologist and her research focuses on the etiological roles of nutritional factors in cancer and chronic disease.
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.
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.
