Dr. Barkoukis is a registered and licensed dietitian who earned her doctorate in nutrition from Case Western Reserve.  Prior to joining our department faculty in 1988, Hope served as a clinical dietitian at MetroHealth Medical Center, was a corporate nutrition consultant for Fortune 500 companies specializing in wellness and sports nutrition interventions.  She was also a clinical research dietitian, and on the faculty of Cleveland State University, where she was the Director of the Nutrition Education and Training Center - a Federally-funded program designed to foster the integration of nutrition education into public (K-12) school curricula. 

Since at Case Western Reserve University, Dr. Hope Barkoukis has distinguished herself as a teacher and as a mentor. And in 2001, she received the John S. Diekhoff Award for Distinguished Graduate Teaching. 

She serves on the Executive Committee of the Academy of Nutrition and Dietetics’ SCAN (Sports, Cardiovascular, Wellness Nutrition) practice group.

Hope’s research interests include nutritional issues among the elderly, including factors influencing glucose metabolism and insulin sensitivity. She also has studied such issues as sports supplementation, food safety, and nutritional management of chronic liver diseases. She has served as the department’s vice chair for the past several months, and is well-suited to lead programs during this time of transition.


Dr. Barkoukis completed advanced training in culinary arts and has taught healthy cooking courses for television audiences as well as professional and community groups.  She has conducted research in the areas of insulin resistance and substrate utilization in hepatic cirrhosis, as well as the use of low glycemic dietary interventions to modulate insulin sensitivity.

Until recently, Dr. Barkoukis was the undergraduate nutrition advisor.  However, she continues to be the primary contact for the current MS in Nutrition Program.

She also teaches the following courses:

  • NTRN 342: Food Science;

  • NTRN 343: Dietary Patterns;

  • NTRN 364 - Human Nutrition II:  Vitamins;

  • NTRN 388: Nutrition for Sports and Fitness;

  • NTRN 440 - Nutrition for the Aging and Aged;

  • NTRN 460 - Sports Nutrition;


In 2001, Dr. Barkoukis was the recipient of the John S. Diekhoff Award for Distinguished Graduate Teaching awarded by the CWRU School of Graduate Studies.


  • Nutritional management of chronic liver diseases such as cirrhosis and hepatitis C.

  • Nutritional issues in the elderly including determination of nutritional status, factors influencing insulin sensitivity, use of the glycemic index to modulate weight and glucose metabolism, sports nutrition and dietary supplementation issues.

  • Issues of food safety.

  • Dietary supplement use, abuse, fraud.
