Jonas specialises in international disputes, including international commercial and investment arbitration and cross-border litigation. He has acted as counsel and advised on large-scale, highly political and sensitive international energy and intellectual property disputes in arbitration proceedings under the ICC, LCIA, NAI and UNCITRAL rules and under a variety of applicable laws. He also regularly engages in enforcement and setting-aside proceedings before Dutch courts.

Jonas’ years of experience in the oil and gas industry include in-house experience gathered during a one year secondment to Shell’s global litigation department in Hamburg (Germany) and The Hague (the Netherlands) offices.

He is a DIS40, ICC YAAF and NAI member as well as part of the selected Dutch-German Arbitration Group, an initiative of the Dutch Arbitration Association, the German Arbitration Institute (DIS) and the Netherlands Arbitration Institution (NAI), aiming to improve mutual knowledge of Dutch and German arbitration practice and to promote personal exchange among arbitration practitioners, in-house counsels as well as users.

Before joining the international arbitration practice, Jonas formed part of De Brauw’s Corporate M&A practice, where he assisted listed companies, large multinationals and private equity firms on public and private transactions.
