Anthony LoPresti, MS ('01), D.D.S.  has been on staff at New York Presbyterian hospital in the Oral, Facial and Head Pain Clinic since 1984. He decided to get his MS in Nutrition to further his ability to help this difficult group of patients. The TMJ (temporomandibular joint) is a susceptible joint to breakdown and significant pain. Dr. LoPresti’s Master’s Thesis focused on the correlation that nutrition, specifically VitC, Vit E and Selenium, has on the health of the joint. Today joint replacements are performed much too quickly. Dr. LoPresti’s thought was that proper nutrition leading to sufficient anti-oxidant concentrations in the joint fluid can decrease the free radical damage that can lead to cartilage and bone damage. His thesis established that a concentration gradient does exist in TM joints as compared to the plasma confirming its protective effect.


Moneek Madra, MS ('06), PhD ('15) is a Lecturer at the Institute of Human Nutrition and Research Associate in the laboratory of Lori Zeltser at Columbia University. She completed her master's of nutrition in 2006 before entering the IHN's Nutritional and Metabolic Biology PhD program.  Her research focuses on Anorexia Nervosa, specializing on neuroendocrine and early postnatal stress outcomes associated with adolescent abnormal feeding behavior.  Her work encompasses several integrative areas including neuroscience, physiology and psychiatry.  The IHN MS program was the catalyst for her interest in basic science research, through classes and her thesis project.  The skills she amassed in the MS program have been invaluable to her research and educational pursuits.
