Associate Professor at the Technical University of Valencia (UPV) and former Scientific Project Officer at the Joint Research Centre, European Commission. Part of VRAIN, ELP and the DMIP Team, and Director of the NEW Master in AI & Big Data Analytics at the UPV. I hold a B.Sc. in Computer Science, an M.Sc. in Software Engineering, Formal Methods and Information Systems, a Post-Graduate Diploma in Engineering Business Management and a Ph.D in Computer Science from UPV. The evaluation and measurement of intelligent systems is, among other more applied research topics, the main scientific-technical objective of my research agenda.
I co-edit the AI Evaluation Digest, a newsletter on AI evaluation research.
