Top SchoolPanagiotis Papadopoulos is a Security and Privacy Researcher with 12 years of experience applying academic rigor to practical anti-fraud and privacy-preserving systems across industry and research labs. Currently at Telefónica Research, he focuses on web security, cyber safety and scalable fraud detection for ad ecosystems and distributed systems. His background includes leading security research at Brave—designing privacy-minded defenses against Sybil, API and ad fraud—and multiple influential studies on cookie synchronization and the value of user data published at top venues. He blends hands-on measurement (RTB auctions, programmatic ad analysis) with protocol and system design, bringing both empirical insight and practical mitigation techniques. Based in London, he has a strong academic foundation (MSc, PhD work) and a track record of translating EU-funded research into deployable tools and papers. Colleagues describe him as someone who uncovers hidden market mechanics (e.g., per-impression pricing from encrypted signals) and turns them into actionable security controls.
