Kostis Hatzitaskos coheads Cornerstone Research’s antitrust and competition practice. Citing his econometrics expertise and significant experience analyzing large datasets, Who’s Who Legal has recognized Dr. Hatzitaskos as a future leader in the competition field, describing him as “a great young economist, great communicator, and a pleasure to work with.”

Dr. Hatzitaskos leads merger review teams for merging parties and government agencies in investigations, both in the United States and internationally. He has extensive experience in all phases of merger review, including lead trial roles on behalf of the government on U.S. v. Aetna/Humana and FTC v. Wilhelmsen/Drew, and on behalf of the merging parties in T-Mobile/Sprint and FTC v. Sysco/U.S. Foods.

His civil litigation experience involves class certification, liability, and damages issues in complex commercial litigation across competition and intellectual property matters. He led a team supporting Dr. Matthew Lynde in the landmark Microsoft v. Motorola trial, which addressed the determination of reasonable and nondiscriminatory (RAND) royalty rates.
