Description of Research Expertise

For over thirty years, I have been involved in the investigation of metabolic diseases, including defects in the hepatic urea cycle and ammonia detoxification, obesity, fatty liver disease, fatty acid oxidation, diabetes, and normal and pathogenic mitochondrial integrity and function. A special emphasis is on development of pharmacotherapeutic interventions to mitigate metabolic derangements of diverse origin. As a director of the Metabolomic Core Facility at CHOP, I have been involved in many projects investigating metabolomic profiling in normal and disease states and in teaching and training new fellow investigators in the field of metabolism.

Description of Other Expertise

As a director of the Metabolomic Core Facility at CHOP, I have been involved in teaching and training graduate students and new fellow investigators in the field of metabolism. I also, have collaborated and contributed to many investigators studying metabolomic profiling in normal and disease states.
As a member of the Institute of Diabetes, Obesity and Metabolism, Perelman School of Medicine as well as an adjunct professor of Biochemistry and Biophysics, Univ. of Penn, I have consulted in various projects dealing with hepatic metabolism, insulin resistance, obesity or diabetes.
