Marie Skłodowska-Curie Actions (MSCA) Postdoctoral Fellow · IDLab (University of Antwerp - imec)

I am a Marie Skłodowska-Curie Actions (MSCA) Postdoctoral Fellow at IDLab (University of Antwerp - imec) under the supervision of Prof. Jeroen Famaey, where I lead the LUNA project on low-power non-terrestrial networks for Ambient IoT. I received my PhD and B.Sc. in Network Engineering from the Universitat Politècnica de Catalunya (UPC) in 2025 and 2020, respectively, and an M.Sc. in Telecommunications Engineering from La Salle - Universitat Ramon Llull (2021). Previously, I was a member of the Wireless Networks Group within UPC's Network Engineering Department.

My research focuses on energy-efficient wireless networks and the IEEE 802.11 standard, with a growing emphasis on bringing connectivity to devices that can no longer rely on batteries. Through my MSCA project LUNA, I work on Ambient IoT — battery-free devices powered by energy harvesting — and its convergence with Non-Terrestrial Networks (satellites, HAPS, and UAVs) to achieve ubiquitous, energy-autonomous coverage. This builds on my broader interests in IoT-related technologies, Wake-up Radio (WuR) systems, LoRaWAN, LR-FHSS, energy-aware scheduling and localization, and power-saving mechanisms for next-generation wireless protocols.

Overview

LUNA integrates Ambient IoT (A-IoT) — battery-free devices that harvest energy from their environment — with Non-Terrestrial Networks (NTN) such as satellites, High-Altitude Platform Stations (HAPS), and UAVs. The goal is to enable maintenance-free, globally reachable IoT sensing in places where terrestrial infrastructure is sparse or absent.

Research Challenges

🔗
Unified connectivity framework
There is no standardized framework to connect A-IoT devices to both terrestrial and non-terrestrial infrastructures. LUNA works toward a coherent architecture spanning both.
⏱️
Energy-aware scheduling
Battery-free devices have unpredictable duty cycles that must be coordinated with fast-moving platforms — calling for scheduling that respects intermittent energy availability.
📍
Energy-efficient localization
Accurate, low-cost localization is needed to schedule communication windows with passing satellites and aerial platforms without draining the harvested energy budget.
