About me

I am Associate Professor in the CSE Department, at IST Univ. Lisbon. I am also an Integrated Researcher at the INESC-ID, member of the GSD group. I am also on the MEF Research Council.

Until January 2020 I was an Assistant Professor in the CSE department at the Faculty of Sciences of the University of Lisbon. Prior to that I was a supervisor in the Computer Laboratory at the University of Cambridge, and before I also lectured at the ISEL and at the University of Aveiro. My first job before settling in academia was as a junior researcher in Portugal Telecom Inovação, back in 2001. I was also a research intern in Telefonica Research Barcelona, in 2009.

I hold a PhD degree from the University of Cambridge, where I have worked with Jon Crowcroft and Ian H. White. I hold an MSc Degree in Telecommunications from Queen Mary University of London (supervised by Laurie Cuthbert and Manuel Duarte) and a Licenciatura (roughly equivalent to BSc+MSc) in Electronics and Telecommunications Engineering from the University of Aveiro.

Research interests

I am interested in computer networks and communication systems broadly, with my core interest being network programmability (Software-Defined Networking, P4). My research today spans internet architecture and network virtualization, synthesis, and security.

Active topics of research:

  • Virtualization of programmable network switches
  • New Internet architectures: information-centric networking and network coding
  • Intrusion detection powered by programmable networks
  • Verification and synthesis of network functions
  • Leveraging programmable network devices for improved measurement
  • Optimal routing in programmable networks
  • Adversarial attacks to self-driving networks
  • Secure Software-Defined Networks
  • Improving BGP security at IXPs
