About Me

I am a PhD student at NOVA University of Lisbon working towards enabling large-scale applications to take advantage of the Edge computing paradigm. I am advised by Professor João Leitão.

My main research interests include:

Decentralization & Web3
Edge Computing
Wireless Ad Hoc Networks
Distributed Monitoring and Orchestration
