Her research centers on EU/UK competition law with specialized focus on digital markets, examining how AI, big data, and digital platforms reshape consumer choice and competition enforcement. She investigates the competition-regulation dichotomy, consumer-law intersections, and effective remedy design in digital contexts, addressing both theoretical frameworks and practical enforcement challenges.

Her recent publications (2018-2023) reveal a concentrated evolution toward digital competition law, with increasing emphasis on AI-driven market dynamics, multi-level governance, and consumer vulnerability in platform economies. Key thematic clusters include digital market remedies, energy sector regulation, and private enforcement mechanisms, reflecting her dual expertise in theoretical scholarship and policy engagement.

Dr Ioannidou actively supervises PhD candidates while leading the Institute for Competition and Consumers. She serves as managing editor of the Journal of Antitrust Enforcement and provides expert testimony to UK parliamentary committees on AI regulation, demonstrating significant policy influence beyond academic contributions.

She coordinates the Journal of Antitrust Enforcement Agency Effectiveness Study and maintains active affiliations with Oxford University's Centre for Competition Law and Policy, driving collaborative research on global competition governance and digital market challenges.
