Round table: Data Quality, the Unseen Foundation of Reliable AI

Luxembourg Software Testing Event (LSTE), hosted by Q-Leap — Luxembourg, November 27, 2025

I joined the round table “Data Quality: The Unseen Foundation of Reliable AI” at LSTE 2025, an event bringing together industry leaders and tech experts around the main trends in software testing.

The discussion combined three perspectives: the technical side of data standardization and preparation for AI, real-world experiences from organizations implementing AI, and the legal and regulatory framework ensuring data compliance. As AI Security Advisor, I focused on AI security challenges and the major risk of using AI without human oversight in testing.

The panel, moderated by Avanti Sharma, brought together:

  • Julien Ehrhart — AI Security Advisor, Thales
  • Liubomyr Bregman — AI & Data, Deloitte Luxembourg
  • Philippe Valoggia — AI Project Officer, Artificial Intelligence, Innovation, and Technology Division, CNPD
  • Cristiano Cunha — Solution Architect & Test Advocate, Xray
