About me

I'm Visiting Associate Professor at the Computer Security Lab from the University Carlos III of Madrid and an external collaborator in the Cambridge Cybercrime Centre from the University of Cambridge. My research interests are manyfold through the field of cybersecurity and cybercrime. Please, see my list of publications (or my Google profile) to get a glimpse of my current interests

I received a PhD in Computer Science and Technology in 2014 by University of Carlos III de Madrid, my alma mater, where I have also taught courses in official studies offered at the University Carlos III about Security and Computer Programming as well as ocassional participation in Master courses, summer schools and workshops.
