Nyhan currently serves as professor of pediatrics at University of California, San Diego School of Medicine in La Jolla, California. He has held positions at Johns Hopkins School of Medicine and the Miller School of Medicine at the University of Miami, and has served on a number of advisory committees, pediatric advisory boards, and research foundation boards.

Nyhan's areas of research span a variety of amino acid metabolism disorders, among them 4-hydroxybutyric aciduria, 3-methylglutaconyl-Co A hydratase deficiency, multiple carboxylase deficiency, methylmalonic acidemia, and propionic acidemia. He has studied the neuropathology of propionic acidemia, including the manifestation of basal ganglia infarction and its neurologic, non-metabolic presentation. Currently, he conducts research into the causes of progressive neurologic disability caused by methylmalonic acidemia following liver transplantation.

He is involved in the ongoing development of tandem mass spectrometry for use in newborn screening and research. In addition, he is investigating the use of dichloroacetate to treat a broad range of mitochondrial diseases that lead to lactic acidemia.
