I am currenty a Senior/Postdoc Researcher at the Systems Group in ETH Zurich. Before joining ETH, I did my PhD in Técnico (University of Lisbon) during which I was part of the Distributed Systems Group (INESC-ID Lisboa).

• Research

  My main research focus is on runtime systems design and implementation. This includes topics such as memory management and Just-In-Time compilers. In parallel, I also work on Operating Systems, and Parallel and Distrubuted Systems.

• Jobs (PhD and Postdocs positions)

  Contact me if you are interested in doing research in areas related to runtime systems. There often open research positions in ETH Zurich (Systems Group), University of Lisbon (INESC-ID Lisbon), and University of Oslo.
