About
Joanna Fiddler is an Assistant Professor in the Department of Food, Nutrition & Packaging Sciences at Clemson University. She earned her B.S. and M.S. degrees in Nutritional Sciences and Health & Human Performance (exercise physiology concentration) before pursuing a Ph.D. in Nutritional Sciences investigating iron metabolism at Oklahoma State University. She went on to study the role of B vitamins in mitochondrial one-carbon metabolism and the effect of moderate iron deficiency on metabolic pathways that influence work capacity during her postdoctoral training at Cornell University in the labs of Dr. Martha Field and Professor Jere Haas. She joined the faculty at Clemson in 2023. Her work focuses on micronutrient nutrition and mitochondrial metabolism and studying their integration in health and disease.

How their research is transforming health care
As a nutritional scientist, Joanna can provide expertise on the use of rodent and cell culture models for human micronutrient nutrition and mitochondrial health research. Her current research efforts are examining: 1) the relationship between mitochondrial de novo thymidylate biosynthesis and the maintenance of mitochondrial DNA integrity with mitochondrial function, and 2) the molecular mechanisms in humans that lead to reduced work capacity in iron deficiency without anemia.
