I am a qualified attorney focusing on complex civil litigation, including securities disputes, international arbitration, and professional liability defense. I represent corporations, financial institutions, law firms, and individuals in high-stakes matters such as class actions, fraud claims, regulatory investigations, and cross-border disputes before federal and state courts, including the U.S. Supreme Court. My work spans industries such as energy and healthcare, where I have defended clients in major securities and commercial disputes. I also have significant experience handling international matters, representing foreign entities and individuals in arbitration and litigation. A core part of my practice involves defending law firms and lawyers in malpractice claims, sanctions proceedings, and litigation arising from corporate failures. One of my notable achievements includes arguing before the U.S. Supreme Court in Turner v. United States (2017) on behalf of habeas petitioners, reflecting my strength in appellate advocacy. I am also committed to pro bono work, including representing asylum seekers and other vulnerable clients. I hold degrees from Princeton (magna cum laude), Harvard Law School (cum laude), and Yale, and I clerked for a federal appellate judge. I have been recognized as a “Next Generation Lawyer” by Legal 500 and a “Rising Star” by Super Lawyers.
