- formal and natural languages
- cybersecurity
- IoT (Internet of Things) and cyber-physical systems
- design, UX (user experience), digital art, front-end and multimodal pipelines
- experimental programming languages
- organisational methodologies and innovation ecosystems
- human-augmented and cognitive cyborg technologies
II. Cultural collections and heritage
To work on the digitisation, preservation, curation and management of cultural, historical, artistic, linguistic and heritage collections, including:
- digital preservation
- digital humanities
- digital and computational restoration
- intelligent cataloguing
- ontologies, metadata, taxonomies and knowledge bases
- 3D modelling, digital reconstruction, virtual museums
- AI applied to cultural preservation
III. Platforms, laboratories and proprietary methodologies
To develop its own platforms, laboratories, software, observatories and methodologies for:
- augmented intelligence
- multimodal analysis
- digital education
- heritage preservation
- innovation and cultural transformation
Lines with published works
Three lines form the core of the corpus. Two applied fronts carry the same method into law and protocol engineering.
Augmented intelligence and the cyborg profile
Studies the human side of the relationship with artificial intelligence: which capacities delegation extends, replaces or atrophies; how to declare authorship and responsibility in work produced with AI; and what training a researcher needs before any augmentation.
