Text Assessment of Total Energy Expenditure Using Doubly Labeled Water - Theory and Applications

Jennifer Rood, Ph.D., DABCC, FACB

Dr. Jennifer C. Rood is an accomplished researcher and Associate Executive Director for Cores and Resources at the Pennington Biomedical Research Center in Baton Rouge, Louisiana, USA. Dr. Rood’s expertise lies in clinical chemistry, mass spectrometry, and energy expenditure measurement. Dr. Rood earned her B.S. in Microbiology from Louisiana State University in 1988. She continued her studies at Louisiana State University Medical Center, New Orleans, where she obtained her M.S. in Pathology (1990) and her Ph.D. in Pathology (1993).

Her primary focus is on measuring energy expenditure in various conditions, including weight gain/loss and intense exercise. Dr. Rood has also contributed to research related to protein metabolism during weight fluctuations. Since 1993, she has received continuous funding from the Department of Defense and her work directly contributes to optimizing warfighter nutrition. Dr. Rood co-directs the Center for Military Performance and Resilience. Dr. Rood is board certified by the American Board of Clinical Chemistry and she holds the distinction of being a Fellow in the National Academy of Clinical Biochemistry. Additionally, she serves on the management committee for the International Atomic Energy Agency’s Doubly Labeled Water database. Dr. Rood’s research findings have been published in over 170 scholarly journals and books. She actively participates in scientific meetings organized by several national and international organizations. Her work significantly contributes to our understanding of energy metabolism and has practical implications for nutrition, particularly in military contexts.
