Daniel is a Senior Staff Attorney at the Prison Law Office. Prior to joining the Prison Law Office, Daniel was Supreme Court and Appellate Counsel at the MacArthur Justice Center, where he litigated jail and prison conditions cases, with a focus on solitary confinement and other inhumane practices. He was counsel of record in both Johnson v. Prentice, 144 S.Ct. 11, 12 (2023) (Jackson, J., dissenting from denial of certiorari) (noting that “the practice of solitary confinement ‘exacts a terrible price’”) and Apodaca v. Raemisch, 139 S.Ct. 5, 8 (2018) (Sotomayor, J., respecting denial of certiorari) (emphasizing the “clear constitutional problems raised by keeping prisoners . . . in what comes perilously close to a penal tomb”). In addition, Daniel co-taught the MacArthur Justice Center’s appellate litigation clinic at Northwestern University School of Law from 2017 to 2022. Before joining the MacArthur Justice Center, Daniel was both pro bono counsel and a litigation associate at Sidley Austin, completed a fellowship at the Center on Wrongful Convictions, and served as a law clerk to the Honorable Diane E. Murphy of the U.S. Court of Appeals for the Eighth Circuit. He received a J.D. cum laude from Northwestern in 2008. He also has an M.F.A. from New York University’s Tisch School of the Arts and a B.S. from Northwestern. Daniel is admitted to the bars of Washington, D.C. and Illinois.
