John joined our Brussels office in September 2019 as a Marine Habitats Lawyer. His work focusses on the laws relating to marine conservation issues, including species protection, plastic pollution, and the conservation of marine habitats.


Before joining ClientEarth, he worked in private practice with the Irish law firm A&L Goodbody, specialising in commercial litigation and regulatory investigations.


John is qualified to practise as a lawyer in Ireland and in England and Wales. He holds an LLM in Environmental Law and Policy from University College London and an LLB in Law from Trinity College, the University of Dublin.

ClientEarth is an incredibly dedicated and innovative organisation, which has used the law with great success to address serious environmental challenges. It is a real privilege for me to work as a lawyer helping to protect and restore the ocean, including all its wondrous species and habitats.
