About Me

I am a Research Scientist at Telefonica Research in Barcelona, Spain.

I am also a collaborator professor at the Universitat Oberta de Catalunya (UOC).

My research interests lie in the areas of Networks and Security. Currently, my work focuses on the security of new networking and computing paradigms such as Software Defined Networking (SDN), P4, Network Function Virtualisation (NFV), Containers or Serverless Computing.

In 2018, I obtained a PhD degree from the COSIC research group (KU Leuven, Belgium) under the supervision of Prof Bart Preneel and Dr Dave Singelée. My doctoral thesis is entitled Security and Privacy of Implantable Medical Devices.

In the past I graduated as a Telecommunications Engineer at the Universitat Politècnica de Catalunya (UPC) (Spain) with the master thesis Security analysis of an implantable cardioverter defibrillator developed at COSIC within the ERASMUS framework. After obtaining my PhD, I was a visiting research fellow in the SPRITZ group at the University of Padua (Italy) and a research fellow in the Security and Privacy group at the University of Birmingham (UK).
