FACULTY  RESEARCH

The research conducted in the CASE Department of Nutrition emphasizes Nutritional Biochemistry & Metabolism, Molecular Nutrition, and Applied Nutrition.¬† This research has been conducted in association with several Cleveland hospitals and other departments within the School of Medicine.  Particular areas of Applied Nutrition have been developed and performed in field settings - both the United States and abroad, in cooperation with multicenter national studies, and in our own department's various laboratories.  These state-of-the-art laboratories are located in the School of Medicine and the Veteran Affairs Medical Center. ¬†Facilities in the Clinical Research Center at University Hospitals Case Medical Center are also available to our department. CASE Nutrition department has all general equipment necessary for conducting studies in nutritional biochemistry and molecular nutrition, including six Agilent Technologies GC-MS (gas chromatographers -mass spectrometers). They are used for human and animal investigation with stable isotopes. Facilities for isolated organ perfusions and a comprehensive organic chemistry laboratory for synthesis of new nutrients are also available. The department has been equipped for body composition measures and diet preparation. Consult the Nutrition Faculty Directory for specific research projects.  A brief summary of each faculty's research focus, shown below.
