Darren Tucker

Darren Tucker is the chair of the firm’s antitrust practice group, where he focuses on merger and non-merger antitrust investigations in the technology, energy and pharmaceutical sectors. Darren draws on both his experience as a former Federal Trade Commission attorney and his more than 15 years in private practice to provide valuable insights to clients regarding competition enforcement and policy issues. He advises clients on a range of pricing and distribution issues and helps clients close mergers, acquisitions and joint ventures worth billions of dollars annually.

In addition to representing clients before the Department of Justice and the Federal Trade Commission, Darren has extensive experience on competition matters outside the U.S., having counseled clients on antitrust matters in Europe, Canada, Japan, China, South Korea, Taiwan, Russia and Australia. He is skilled at collaborating with local counsel around the world, and he is among the few attorneys whose practice includes global dominance investigations. In 2017, Global Competition Review recognized him as one of the leading antitrust lawyers under the age of 45.

Darren regularly speaks and writes on antitrust issues relevant to technology, energy, and life science companies, as well as on competition agency practice and procedure. He has taught an advanced antitrust seminar as an adjunct professor at Antonin Scalia Law School at George Mason University and has served in various editorial advisory positions for publications such as Antitrust Law Developments, the ABA’s Antitrust Source and Law360 Competition. He has been part of the leadership of the American Bar Association’s Section of Antitrust Law for over a decade, where he currently serves on the Section’s governing council.
