-> Professional Experience

Researcher, CTTC, (2019-Current):
- Advanced AI for B5G network slicing management, where I have developed a variety of novel deep and federated learning algorithms by leveraging solid mathematical analysis and statistical tools to allow low-complexity prediction and resource allocation, low-overhead, and 10x energy-efficient network slicing, which has led to high-quality publications in top-tier journals and conferences (e.g. IEEE JSAC, ICC).
- Research Projects: MonB5G, where I am involved through technical research, publications, deliverables, project workshop presentation and/or organization.
- Participation in proposals: 5GMediaHUB (H2020, granted), 6GDAWN (Spanish)
