BLB&G has expanded its securities litigation practice with the addition of Partner Li Yu in the firm’s New York office. A seasoned trial and appellate lawyer, Li has extensive experience in healthcare fraud, financial fraud, and other types of complex litigation.
Li is a recognized authority in qui tam cases, a type of whistleblower lawsuit brought under the False Claims Act. He has successfully litigated high-stakes cases in the Southern District of New York, exposing fraud and securing over $800 million in settlements against Medicare Advantage organizations, drug manufacturers, pharmacy chains, medical device suppliers, and mortgage lenders.
“We are thrilled to welcome Li, whose whistleblower expertise will further strengthen and expand our world-class securities practice,” says Partner John Rizio-Hamilton. “We look forward to Li building a robust whistleblower practice and providing another avenue for our firm to hold corporate America accountable when it crosses the line.”
In addition to his whistleblower work, Li has extensive experience in securities enforcement and congressional investigations. He previously served as investigative counsel at the Financial Industry Regulatory Authority and as senior counsel to the Senate Permanent Subcommittee on Investigations under Sen. Jon Ossoff. In these roles, he led impactful investigations that held wrongdoers accountable, including exposing mistreatment of military families by a major housing contractor and uncovering sexual abuse of women prisoners by federal prison staff.
“Our firm has successfully prosecuted numerous healthcare-related cases, and Li will significantly enhance our capabilities in this area,” says Partner Avi Josefson. “His deep expertise in whistleblower claims and vast experience prosecuting healthcare fraud will be invaluable in our continued efforts to advise institutional investor clients regarding such matters.”
BLB&G prosecutes class and private actions on behalf of individual and institutional clients. Since its founding in 1983, the firm has obtained over $40 billion on behalf of investors—including many of the largest monetary recoveries in history—and achieved precedent-setting corporate governance reforms that have increased market transparency, held wrongdoers accountable, and improved corporate business practices in groundbreaking ways.
