He joined the Biochemistry, Cellular and Molecular Biology graduate program and studied under Dr. Solomon Snyder in the Department of Neuroscience. In graduate school, he discovered that the heme metabolite bilirubin binds and activates the orphan receptor MRGPRX4 in itch sensory neurons, potentially contributing to itch in hepatobiliary disease. He also identified that bilirubin is a physiologic antioxidant with distinct redox activity that negatively regulates superoxide signaling during neurotransmission.
