Research Interests

Machine Learning for Healthcare

Interested in the research on machine learning and time-series analysis algorithms able to process big data in an efficient, adaptive, and robust way. Currently focused on their application to Cognitive Stimulation and Rehabilitation (see Innobrain and Cognitio projects) and Autism Spectrum Disorders (see AMATE project).

Machine Learning for Music

Another topic of my interest is the use of Machine Learning techniques to reason and learn about musical processes like expressive music generation.
Currently focused on the study of musical expressivity in Nylon Guitars (see guitarLab) and social tools for music education (see PRAISE).
We have studied the issue of expressiveness in the context of tenor saxophon interpretations (see Saxex and TempoExpress systems) in collaboration with the Music Technology Group (UPF).

Case-Based Reasoning

Interested in the design of Knowledge-Intensive CBR systems and the techniques involved in retrieving and adapting highly structured cases (see our CBR Homepage). Currently focused on the design of CBR systems with introspective capabilities for autonomously improving the retrieval and adaptation steps (see NEXT-CBR project).

Self-* Systems

Mainly focused on the study of self-organization and self-adaptation in the context of autonomic electronic institutions (see EVE and AT Projects).

Innobrain: New technologies for the innovation in cognitive stimulation and rehabilitation
AMATE: Data-Mining for Therapeutic Analysis of Behaviors in Autism Spectrum Disorders
Draga: Digital Reconstruction of the Prehistoric Past
NASAID: New trends of ML systems for data-based computer science
CityBeats: Meaningful civic engagement to build human cities

Research Scientist at the Artificial Intelligence Research Institute (IIIA-CSIC) since 2009.

Visiting Researcher at Indiana University, collaborating with Dr. David B.Leake, School of Informatics and Computing (2005).

Tenured Scientist at the Artificial Intelligence Research Institute (IIIA-CSIC) from 2000 to 2009.

Head of the Technology Transfer Unit (UDT-IA) at de IIIA-CSIC from 2002 to 2007.

Ph.D. on Computer Science by the Technical University of Catalunya (UPC) in 1997. The Phd was devoted to the design and implementation of the Noos representation language (Advisor Enric Plaza). The Noos language is a reflective object-centered representation language for developing knowledge systems that integrate problem solving and learning. Learning methods were introduced as reasoning methods with introspection capabilities able to improve/modify the knowledge of the system.

M.Sc. on Music Creation and Sound Technology by the Universitat Pompeu Fabra (UPF) in 1996. The master thesis was devoted to the design and implementation of Saxex.

M.Sc. on Computer Science by the Facultat d'Informàtica de Barcelona (FIB) of the Technical University of Catalunya (UPC) in 1992. The master thesis was devoted to the design and implementation of a compiler for the MILORD II language. This language is focused to the incremental construction of knowledge bases by means of its modular, refinenent and generic description capabilities.

Degree on Computer Science by the Facultat d'Informàtica de Barcelona (FIB) of the Technical University of Catalunya (UPC) in 1991.

Born in 1968 in Callús (El Bages, Catalunya).
