Senior Researcher at HASLab, working on high performance computing in both parallel and distributed systems.


Braga, Portugal

Currently he is a senior researcher at HASLab and MACC, University of Minho & INESC TEC , working on high performance computing in both parallel and distributed systems and former query engine technical director at LeanXcale. He obtained the Ph.D in the MAP-i Doctoral Programme in Computer Science in 2012. He has a strong background in distributed systems and large scale data management and around 15 years of experience in national and international research projects in distributed systems: secure and large scale query processing, cloud computing, NoSQL and SQL databases, and database replication. He had worked in several European research projects CloudDBAppliance, CrowdHealth, BigDataStack, VineYard, CoherentPaaS and LeanBigData, CumuloNimbo, Gorda. He had co-supervise several research grant holders and master thesis and currently is co-supervisor of 2 PhD students. He had published research papers on large scale and dependable distributed systems and has served as reviewer for several highly reputed conferences such as Eurosys, SRDS, Middleware, DSN, OPODIS, LADC, DAIS. He has also created and served as chair of the WPSDS workshop.

Do you want to work with me and be part of the MACC team? I’m looking for Master’s and PhD students to join in the following topics: energy-efficient HPC scheduling and applications; HPC, Big Data, and AI Convergence Towards Exascale; Scalable data processing. Then send me a short bio with a brief description of the work/research you would be most interested in undertaking.


Dec 13, 2021 I’m happy to announce our poster paper titled “Adaptive Database Synchronization for an Online Analytical Cloud-to-Edge Continuum” has been accepted for publication at the 37th Annual ACM Symposium on Applied Computing 2022.
