Gretchen Casazza, Ph.D.

  • Research Director, UCD Sports Medicine, Department of Neurobiology, Physiology, and Behavior
  • GGNB Faculty
Research Description: Applied research to improve the health and exercise performance of active individuals. Current research projects include optimizing exercise training and performance in competitive athletes, the effects of exercise on the treatment of depression, effects of estrogen on knee osteoarthritis, the effects of oral contraceptives on bone health and exercise performance, ACL injury prevention programs, sports nutrition and metabolism.

Susan Zunino, Ph.D.

  • Adjunct Associate Professor, Department of Nutrition; Research Molecular Biologist, Western Human Nutrition Research Center
  • GGNB Faculty
Dr. Zunino’s lab is interested in how phytochemicals regulate immune response. Obesity increases the risk of developing viral and bacterial infections compared to normal weight individuals. The focus of the laboratory is to understand how dietary phytochemicals may modulate the innate immune response to decrease the risk of infection in the obese.

Angela Zivkovic, Ph.D.

  • Assistant Professor, Nutrition Department; Assistant Nutritionist, Agricultural Experiment Station
  • GGNB Faculty
Dr. Zivkovic’s research is focused on the role of diet and nutrition in Precision Health. Precision Health emphasizes individually tailored approaches to optimize health and prevent disease. The Zivkovic Lab has four overall research themes: 1) Investigating the functional biology of HDL; 2) Assessing the effects of diets and dietary constituents on inflammation; 3) Integrating clinical, metabolomic, proteomic, glycomic, transcriptomic, and genomic approaches to characterize metabolic phenotypes and their responsiveness to different diets; and 4) Investigating the effects of diets and dietary constituents on the gut microbiota and how they in turn affect host health.

Sheri Zidenberg-Cherr, Ph.D.

  • Specialist in Cooperative Extension, Department of Nutrition
  • GGNB Faculty
Dr. Zidenberg-Cherr’s research program studies the impact of multi-faceted approaches to nutrition education on the dietary and lifestyle choices of school-aged children. Her research utilizes a food systems approach in the development and testing of nutrition education curricula and comprehensive nutrition education programs for school age children. She also co-directs the Center for Nutrition in Schools in the Department of Nutrition at University of California, Davis. The goal of the Center is to provide state-of the-art research, outreach, and educational programs to improve the nutrition knowledge, skills, and health outcomes of the nation’s children, assisting them in achieving their full potential academically, socially, and physically.
