I am a clinician and researcher in the field of Clinical Genetics. My role in the medical team is to utilize state of the art genetic testing to diagnose genetic disorders. I strive to provide accurate answers to guide clinical interventions and to increase chances of successful outcomes. Patients referred to my clinic present with a variety of symptoms including developmental delays, autism, growth delays, hypoglycemia and other metabolic problems. I lead through investigations on the possible genetic causes underlying their conditions, ensuring the most advanced genetic testing is used for each individual patient. As a Geneticist, I make sure to spend enough time with each child and family to provide the best information available, counseling, and guidance in the diagnostic and treatment process. My clinical expertise includes inborn errors of metabolism, chromosomal and single gene disorders, among others.

Professional Interests:

  • Glycogen metabolism, lactate and pyruvate metabolism, and development of novel therapies for metabolic defects of energy generation.
