While there, she worked on many large and high-profile cases across a range of sectors. She also contributed to the design of the regulator’s policy framework and operations and promoted its place in the network of European competition authorities.

With her long experience in this area, Lefkothea can provide extensive and in-depth expertise both on the procedural aspects and substantive application of Greek and EU competition law, as well as on the workings and policy direction of the respective regulators. This combination of practical and policy expertise gives Lambadarios a genuinely differentiated client offer in the area of antitrust and competition law.
