Research Interests

My clinical research is focused on bioethical issues including the intersection of genetics, privacy, and decision-making and pediatric ethical issues such as parental authority and equitable access to medical interventions. My basic science research is primary focused on inborn errors of metabolism. My laboratory uses animal and cellular models of glutaric aciduria type I (GA I) and pyridoxine-dependent epilepsy (PDE). We partner with clinicians, scientist and families to investigate the role of biochemistry, current treatment paradigms, and clinical outcomes.
