Sarah is a visiting professor at the University of Bedfordshire, where she teaches international investment arbitration. She has spoken and published extensively on topics relating to international arbitration and cross-border issues, including climate change, the resolution of energy disputes, third-party funding, collateral attacks on arbitration in national courts, improving efficiency in international arbitration, and corruption.
