Research

Dr. Pencharz focus is upon amino acid metabolism and requirements across the life-cycle from newborn infants to adults. In addition, he is interested in the effects of disease on protein, amino acid and energy needs. Recent studies have included patients with inborn-errors of metabolism as well as subjects on parenteral feeding.
