Jessica Tseng Hasen is passionate about leveraging technology to optimize client outcomes in a defensible and efficient manner and approaches leading-edge e-discovery problems with a multidisciplinary understanding of the legal and business issues that matter most to her clients.

Jessica is known for her work on high-stakes, complex matters, including a matter involving over 55 million records, multiple multidistrict litigations, and investigations by several regulatory agencies and legislative bodies; and a Technology Assisted Review (TAR) of one million documents in two months in response to a Hart-Scott-Rodino second request.

Jessica's experience includes strategic e-discovery counseling and TAR workflow design for complex commercial litigation; voting rights and redistricting litigation; copyright, patent, and trade dress infringement; U.S. Securities and Exchange Commission (SEC) and U.S. Department of Justice investigations; qui tam actions; internal corporate investigations; Federal Trade Commission merger evaluations and second requests; and antitrust matters.
