Bonnie helps clients navigate internal and government antitrust investigations, enforcement proceedings, and class action litigation in federal and state courts. She leverages her over 15 years of experience in civil and criminal antitrust litigation and investigations to advise clients across a range of industries that face government scrutiny, including technology, manufacturing, media, telecommunications, healthcare, and financial services.

A dynamic litigator and trial lawyer, Bonnie has significant experience defending class actions, multidistrict litigations, and enforcement actions, and deftly handles international competition investigations and enforcement issues. She has tried several bench and jury trials to verdict, and recently served as lead trial counsel in an antitrust class action jury trial. She has defended companies in antitrust and related complex litigation involving claims of price-fixing, output suppression, monopolization, predatory pricing, and group boycott, as well as prosecuted antitrust counterclaims in patent and IP infringement matters. In addition to her work in the antitrust area, Bonnie has represented clients in various complex commercial litigation and alternative dispute resolution matters relating to unfair competition, RICO, TCPA, and intellectual property claims.

Bonnie devotes herself to promoting diversity and inclusion in the legal community, currently serving co-chair of the Women’s Leadership Network for the National Asian Pacific American Bar Association; incoming co-chair of the Board the ABA Antitrust Section’s Women.Connected; and outgoing chair of the Leadership Council for Legal Diversity Alumni. Bonnie also maintains a robust pro bono practice, and received the 2021 Partner in Justice Award from the Center for Justice and Accountability for her work on a human rights case representing Haitian victims of torture, arson, and extrajudicial killing.
