David Brynmor Thomas KC is a leading international commercial arbitrator and mediator.  Having originally qualified in Medicine, David went on to study law and has specialised for many years in construction, projects and energy disputes whilst remaining comfortable dealing with cases that have a highly scientific or technical basis, including statistics, organic and inorganic chemistry, microbiology, pharmacology, biotechnology and metallurgy.

Teaching, writing and other arbitration related activities

David is an honorary professor of law in the School of International Arbitration in the Centre for Commercial Law Studies at Queen Mary University of London, where he teaches International Construction Contracts and Arbitration.

In recognition of the under-representation of women on international arbitral tribunals, in 2015 members of the arbitration community drew up a pledge to take action (the Pledge). The Pledge seeks to increase, on an equal opportunity basis, the number of women appointed as arbitrators in order to achieve fair representation as soon as practically possible, with the ultimate goal of full parity. Having signed both the Pledge and subsequent pledge for the same diversity of Expert Witnesses, David continues actively to encourage diverse panels within arbitral proceedings and at conferences and similar activities when in a position to do so.  David, continues to observe and support this pledge in his independent practice.
