Solicitor and Tenured Professor of Law


About me

I am a dual-qualified lawyer admitted to practice in England & Wales and Turkey with over 10 years of international arbitration experience. I hold a Ph.D. in International Investment Law from the University of Cambridge in the UK. My thesis “Judicial Acts and Investment Treaty Arbitration” was published by Cambridge University Press and was awarded the International Chamber of Commerce World Business Law Prize.


I combine practice as counsel, arbitrator, and expert in treaty and commercial arbitration cases, alongside my academic career. I have taught at the Centre for Commercial Law Studies (CCLS) of the Queen Mary, University of London, and hold a tenured professor (docent) position at the Galatasaray University Law School in Istanbul, where I teach International Investment Law and Arbitration, International Commercial Litigation, and Private International Law.


I am an ICC Turkish National Committee member. I am also a member of the ISTAC Expert Commissions on the Revision of the ISTAC Arbitration Rules, and I am responsible for all contributions regarding Turkey to the 1958 New York Convention Guide database maintained by Columbia Law School in New York, as well as the “Investment Claims” database of the Oxford University Press. More recently, I have also contributed to Investment Law and Arbitration Wiki for Jus Mundi.
