Bio

Exploring the nutrition of traditional and cultural foods, and, the use of novel tools in applied nutrition science.

Dr. John Gieng is an Assistant Professor in the Department of Nutrition, Food Science & Packaging, College of Applied Sciences and Arts, at San José State University where he has been a faculty member since 2017.

John completed his postdoctoral training in the Center for Nutrition and Metabolism at Children’s Hospital Oakland Research Institute (CHORI), his Ph.D. in Nutritional Sciences (Minor: Physiology) at The Pennsylvania State University and his B.S. in Nutritional Sciences: Physiology & Metabolsim at the University of California, Berkeley.

His research interests include:

  • health and nutrition of traditional, cultural, and fermented foods
  • role of food preparation techniques in nutrition, health, and disease
  • nutritional value of sustainable food sources and systems
  • effect of nutrition on performance and productivity
  • efficacy of novel tools and biomarkers of health and disease

John has done research in nutrition ranging from basic laboratory science to applied community education. In this capacity, he has utilized both in vitro and in vivo models for this work (human and animal cell culture, rodents, and humans). His early research examined, through the use of mathematical modeling in a biological system, the effects of acute and chronic inflammation on the kinetics of vitamin A to better understand nutrient deficiency in the context of concurrent disease and inflammation. His research focus then shifted to understanding the role and interactions of gut microbiota with host physiology and health in the context of diet-induced obesity and chronic inflammation. His recent research sought to understand the efficacy of teenagers as teachers of elementary-aged children in a garden-enhanced nutrition education setting, and, how this experience might improve teen self-efficacy and empowerment to live healthier lives. At San José State University, John hopes to bridge his knowledge of basic science and applied community work into his research.

In his spare time, John likes to run and hike long distances as a way to mentally recharge and stay healthy.
