As a member of our Appellate practice, Erin Chapman helps clients make their case on appeal in cases involving a wide range of issues, including constitutional law, telecommunications, health care, jurisdiction, and others.

She has briefed numerous appeals and dispositive motions in federal and state court at every level and argued in the Sixth Circuit Court of Appeals. Erin has also briefed and assisted with oral argument preparation in four merits cases at the U.S. Supreme Court, including the firm's victory in McDonough v. Smith, which made it easier to hold public officials who fabricate evidence accountable. As part of her robust pro bono practice, Erin has advised voting rights organizations on litigation strategy and has challenged the Trump administration's attempt to rollback anti-discrimination protections in the Affordable Care Act.

Prior to joining Hogan Lovells, Erin clerked for Judge John M. Walker, Jr. of the U.S. Court of Appeals for the Second Circuit.

Erin graduated magna cum laude from the University of Michigan Law School, where she served as Editor-in-Chief of the Michigan Law Review and received the Irving Stenn, Jr. Award for leadership and contributions to the law school community. Before law school, she taught middle school social studies as a Teach for America corps member.
