Tuuli Timonen

Tuuli is the head of Dottir’s dispute resolution department. She holds close to two decades of experience in resolving complex international disputes arising out of a variety of industries, such as technology, energy, construction, and post M&A. Tuuli’s practice focuses on arbitration and other forms of ADR, with a particular emphasis on cross border disputes.

In addition to successfully representing parties in contentious proceedings, Tuuli has extensive experience assisting companies in developing conflict management strategies – from the early stages of a dispute through to its resolution – and supporting them in amicable dispute resolution processes. Indeed, Tuuli has reached settlements in high value disputes through negotiations, mediation and other ADR methods.

Tuuli also regularly sits as arbitrator in commercial arbitrations, both national and international.

Tuuli is a court member of the ICC International Court of Arbitration, and a former long-standing member of the board of the Arbitration Institute of the Finland Chamber of Commerce. She is also an Officer of the Arbitration Committee of the International Bar Association.

Prior to joining Dottir in 2024, Tuuli worked in the international arbitration department of White & Case in Paris, Helsinki and New York for a decade. For the years preceding her joining Dottir, Tuuli was the director of disputes at Nokia Technologies, where she managed global disputes and contentious licensing deals arising out of the licensing of a global patent portfolio. Tuuli has authored several publications on the topics of dispute resolution and governing law, and she is a regular speaker on these topics.

Tuuli is recognized by Chambers Global as one of the leading dispute resolution experts in Finland, as well as by Lexology Index for her expertise in arbitration.

"She is one of the best in arbitration cases."

"Tuuli Timonen is consistently high performing and proactive, and brings a great deal of energy and dedication to her work."

"She has a very strong understanding of the client's business and interests."
