I have been consulting and testifying on liability, damages and policy issues for antitrust and regulatory matters since the early 1980's. I specialize in high-tech industries, with extensive experience in the Internet, e-commerce, computer software and hardware, telecommunications, high-volume copiers, and computer services. I have testified by deposition and/or at trial in over two dozen federal cases, including at trial for the plaintiffs in ITS v. Kodak, for the defendant in Tricom v. EDS, for the defendant in The Service Source v. Office Depot, and for the plaintiffs in the California class action against Microsoft Corp. which ended in a $1.1 billion settlement for California consumers. I have also submitted reports and testimony in numerous regulatory proceedings, and provided antitrust economics advice to many other clients.
