Dr. Joanna Fiddler is an Assistant Professor of Human Nutrition at the University of Arkansas, affiliated with the Dale Bumpers College of Agricultural, Food and Life Sciences. She holds a PhD in Nutritional Sciences from Oklahoma State University and completed postdoctoral training at Cornell University's Division of Nutritional Sciences.
Education:
- B.S. in Nutritional Sciences, Oklahoma State University
- M.S. in Health and Human Performance (Exercise Physiology), Oklahoma State University
- Ph.D. in Nutritional Sciences, Oklahoma State University
- Post-Doctoral Training in Molecular Nutrition, Cornell University
Research Focus: Her work centers on micronutrient nutrition and metabolism, particularly investigating mitochondrial function, folate/vitamin B12 pathways, iron deficiency mechanisms, and nutritional interventions. Key themes include:
- Mitochondrial DNA integrity and metabolic disorders
- Nutrient-gene interactions in health and disease
- Diagnostic tools for nutritional deficiencies
Recent Work Trends: Recent publications emphasize mitochondrial dysfunction in cardiovascular contexts, vitamin deficiencies' genetic impacts, and novel diagnostic methods for micronutrient status assessment. Experimental models include mouse and rat studies alongside clinical trials in human populations.
Grants & Collaborations: Research supported by NIH grants and collaborations with institutions like Cornell University. Active in translational research bridging basic science and clinical applications.
Labs & Teams: Leads nutritional metabolism research in the School of Human Environmental Sciences lab focused on cellular energy systems and micronutrient biology.
