Joseph is one of Oxera’s expert advisers in the field of competition litigation. He heads Oxera’s Follow-on Damages practice in the UK, with a focus on collective actions and cartel damages.

Able to work across jurisdictions, Joseph has led projects providing evidence to competition authorities (including the CMA and the European Commission) and national courts in the UK and the Netherlands.

One of Joseph’s noted skills is making complex economics concepts practical, relevant and clear, and he has experience of providing expert testimony in the UK and to the European Commission. He regularly contributes to Oxera’s EU-sponsored courses on the quantification of competition damages for member state judges.
