Dr Simpson



Dr. Katherine Simpson, FCIArb., is an arbitrator based in the US (through Simpson Dispute Resolution) and in London, United Kingdom (33 Bedford Row Chambers).  She has been involved in over 30 international commercial and investment arbitrations, chaired by Profs. Karl-Heinz Böckstiegel, William W. (Rusty) Park, and Klaus Peter Berger, among others.  These cases had amounts in controversy ranging from US$ 5 million to US$ 2.5 billion and have become the most influential cases of the past decade, including Bear Creek v. Peru (ICSID 14/21) (elaborating the need for a “social license” to conduct business), and UP v. Hungary (ICSID 13/35) (Global Arbitration Review’s “Most Important Award” of 2019, regarding the Achmea Decision’s impact on ICSID jurisdiction).

In 2019, Dr. Simpson was invited to join the AAA-ICDR international panel.  She has experience in investor-state arbitration (7 cases), commercial, life sciences, telecommunication, construction, energy, mining, oil & gas, human rights, and financial disputes, as well as disputes related to joint ventures.

She has served as sole arbitrator in international disputes conducted under the Commercial Rules of the American Arbitration Association ("AAA") and has experiences in cases conducted under the rules of the International Chamber of Commerce (“ICC”), London Court of International Arbitration (“LCIA”), Dubai International Arbitration Centre (“DIAC”), the German Institution of Arbitration (“DIS”), and the Chinese European Arbitration Centre (“CEAC”).  Dr. Simpson has served in ad hoc arbitrations using the United Nations Commission on International Trade Law (“UNCITRAL”) Rules (2010) and in investor-state arbitrations before the Stockholm Chamber of Commerce (“SCC”) and the International Centre for Settlement of Investment Disputes (“ICSID”).
