Biography/Curriculum Vitae:

Research Interests:
Pediatrics; child development; inherited disorders of amino acid and ammonia metabolism

Narrative of Current Research Efforts:
I am a pediatrician with an interest in inherited disorders of amino acid and ammonia metabolism. These disorders alter brain function and, if untreated, cause brain injury. My goal is to understand the mechanisms responsible for such damage and to develop novel treatments such as gene therapy, which may restore specific enzymes to children who congenitally lack them.
To this end, I study both cultured brain cells and children with congenital disorders. The aim of my cultured cell work is to understand how the brain produces and consumes glutamic acid, the linchpin of all brain amino acid metabolism and the most important excitatory neurotransmitter in the nervous system. I am also studying children with ornithine transcarbamylase deficiency to measure, both before and after gene replacement therapy, the rate of production of urea from ammonia.
