About Us

Investment Arbitration Reporter is a news and analysis service focusing on the international law that applies to foreign investment, particularly the international investment treaties and arbitration claims that arise in this context.

We offer detailed and nuanced coverage, with a particular focus on investigation of unreported cases and rapid review and analysis of legal documents and important policy developments.

Our contributors are subject-matter experts with advanced degrees and/or practice-experience in the investment law field, thus distinguishing our reports from more conventional media reporting.


Luke Eric Peterson (Editor) founded IAReporter in 2008. In the early 2000’s he worked as a consultant to various NGOs and IGOs on the then-emerging topic of investment treaties and legal claims thereunder. A journalist by vocation, he also wrote on these themes for mainstream media including the Financial Times and The Economist, but soon realized that it was impossible to do justice to the technical nuances of this field in 400 word articles for general audiences. He launched IAReporter so as to investigate and report systematically on the use and application of investment protection treaties around the world. Luke obtained a Masters in Legal & Political Theory at University College London. He also studied as a Rhodes Scholar at the University of Oxford, obtaining a Masters degree in history. A native of Canada, he now lives in Los Angeles, CA and can be reached at editor[at]

Jarrod Hepburn has been a regular contributor since 2009. Jarrod holds a doctorate in law from the University of Oxford and is qualified to practice law in Australian federal and state jurisdictions. In July of 2018, he joined the permanent academic staff of Melbourne Law School as a Senior Lecturer. He is the author of the recent Oxford University Press title Domestic Law in International Investment Arbitration – a work based on his doctoral dissertation. He can be reached at jh[at]

Damien Charlotin is a PhD candidate in law at the University of Cambridge (UK), where he focuses on authorities-based argumentation in international dispute settlement, on an empirical basis. Prior to this, he studied international law at SciencesPo Law School in Paris and Columbia Law School.

Lisa M. Bohmer holds a PhD in international arbitration law from the Sorbonne Law School in Paris. Her research focused on public law and international arbitration. She also holds an LLM in energy law from the University of Houston and is admitted to practice in Texas. Before she became an IAReporter contributor, she was part of the arbitration team of an international law firm.

Zoe Williams, a native of Canada, obtained her doctoral degree in 2016 from the Berlin School for Transnational Studies. Her research focused on the domestic political and institutional determinants of investor-state disputes. She is currently pursuing post-doctoral research at the London School of Economics

Joel Dahlquist Cullborg is a doctoral candidate and lecturer at Uppsala University, Sweden, focusing on the use of commercial arbitration rules in treaty disputes. He is a former Associate Counsel with the Arbitration Institute at the Stockholm Chamber of Commerce, and the current co-host of The Arbitration Station podcast. He rejoined IAReporter in October of 2018, while he puts the finishing touches on his dissertation.

Ridhi Kabra is a Lecturer at Bristol Law School in the United Kingdom, and a PhD candidate in law at the University of Cambridge (UK).

Vladislav Djanic is a PhD candidate at the University of Amsterdam, where he focuses on the history of arbitration involving states or state-entities.

“Luke Eric Peterson is the world’s leading journalist writing about investment law and policy. His Investment Arbitration Reporter service is an invaluable tool which I use to keep track of the latest developments and trends in the field of investment law and policy. I often recommend it to my academic colleagues, my students, and to practitioners.”
Christoph Schreuer, former Professor of International Law, University of Vienna; Author of The ICSID Convention: A Commentary (Cambridge University Press)

Investment Arbitration Reporter provides reliable and impressively timely information on investor-state arbitrations – including otherwise unpublicized non-ICSID cases. Thanks to the long experience and expertise of its editor, Luke Eric Peterson, the service offers not merely case summaries but also useful insights and analysis on recent developments in this rapidly growing and important field.”
Antonio Parra, former Deputy Secretary General, International Centre for Settlement of Investment Disputes (ICSID)

“It is increasingly difficult to stay on top of the latest developments in investor-state arbitration given the growing numbers of decisions and awards. Investment Arbitration Reporter is an essential tool for those in academia, government or private practice, since it provides excellent summaries of published and unpublished cases, as well as very useful and up to date information and analysis”.
Ignacio Suarez Anzorena, former Lead Counsel with Argentine Government’s investor-state arbitration claims division

Investment Arbitration Reporter’s work is unrivaled. Mr. Peterson’s reporting was especially useful for me when I was working to improve Japan’s investment treaty model. In several instances, decisions by the Government to pursue particular negotiating strategies were influenced by lessons learned from Mr. Peterson’s reporting and analysis.”
Miyake Yasujiro, Japanese Ministry of Economy, former Investment Treaty Negotiator

“Astute analysis and measured commentary on a complex and opaque area of international law.  Investment Arbitration Reporter is a valuable resource for understanding the public policy implications of international commercial disputes.”
Matthew Sanger, Senior Advisor, International Affairs Directorate, Health Canada, Canadian Government

“Luke Peterson doesn’t just cover arbitrations. He uncovers them.”
Michael Goldhaber, Senior International Correspondent, The American Lawyer magazine
