“The OECD HAIP Reporting Framework: Its value in global AI governance and recommendations for the future”

In collaboration with the Brookings Institution, I contributed to an analysis of the HAIP Reporting Framework, a voluntary mechanism promoted within the G7 framework for large AI providers to report on their risk management and transparency practices. The work assesses the value of this reporting framework in fostering trust, compares the practices implemented by different organizations, and offers recommendations for strengthening its impact.

Recomendaciones sobre las modificaciones del “AI Digital Omnibus”

Legal analysis of the main amendments proposed by the European Commission to the AI ​​Regulation within the framework of the Digital Omnibus Directive, carried out in collaboration with AI Standards Lab, a non-profit organization with which I collaborate in Brussels.

This work offers a detailed assessment of the most relevant proposed changes and formulates concrete and actionable recommendations for European co-legislators. These recommendations were developed following technical exchanges with members of the European Parliament and Commission, as well as organizations specializing in digital law. Among others, working meetings were held with representatives directly involved in the European AI regulation, such as Brando Benifei and Michael McNamara.
