WASHINGTON, D.C. – Keystone, a global advisory firm that guides the most critical technology and science-based platforms and ecosystems, today announced the appointment of Karthik Hemmanur as Partner and Head of its Washington, D.C. office.

Hemmanur brings extensive expertise in tax, financial economics and valuation, advising leading companies and law firms on complex disputes, transactions and strategic matters. His work spans transfer pricing, international tax, intellectual property valuation, financial analysis and litigation support. He is known for bringing together multidisciplinary teams of economists, financial specialists, technologists and industry experts to address clients’ most consequential challenges.

The appointment builds on Keystone’s continued investment in Washington, D.C., where the firm opened a new office earlier this year and recently welcomed former U.S. Department of Justice antitrust economists Malika Krishna and Brian Clark as Partners. Under Hemmanur’s leadership, the office will continue expanding Keystone’s capabilities and client relationships at the intersection of economics, technology, law and public policy.
