João Pedro Barreto

I'm a researcher of the Distributed Systems Group at INESC-ID, Lisboa, and assistant professor at Instituto Superior Técnico. My current research interests include: Transactional Memory, Consistency and Replication, Data Deduplication, Mobile Sensing.

Looking for a MSc/PhD along these topics? Take a look here to know about some possible thesis topics. Feel free to drop me an email.

These smart students are currently working with me on their theses: Ricardo Filipe (PhD), Amin Mohtasham (PhD), David Gureya (PhD), João Neto (PhD), Pedro Alcobia (Motiv project), Duarte Baptista (Motiv project), Manuel Henriques, Paulo Martins (MSc), Ricardo Jesus (MSc).

This semester I'm teaching Operating Systems and next one I'll be teaching Distributed Systems.

I'm the local coordinator of the European joint Effort toward a Highly Productive Programming Environment for Heterogeneous Exascale Computing (EPEEC).
