About me - PhD (with distinction)

I am an Assistant Professor at IMDEA Networks Institue. I am also part of the Cybersecurity research group at King's College London (KCL), where I hold a position as Lecturer.

I was previously at the Information Security Group in University College London (UCL) working as a senior research associate with Gianluca Stringhini. My main focus is on detecting and preventing mass-marketing fraud (see DAPM project). My interests in security range from malware detection, security in smart devices, intrusion detection, and other cyber security areas. Prior to joining UCL, I was at the Information Security Group in Royal Holloway, University of London (RHUL) as a postdoctoral research assistant.

I received a PhD in CS with distinction in the Computer Security (COSEC) Lab at Universidad Carlos III de Madrid, Spain. I have participated in various research projects related to network security and trusted computing. I hold a B.Sc. and a M.Sc. in Computer Science from Universidad Carlos III de Madrid. Best academic award for the M.Sc. and PhD.

Security Dissemination

Teaching - Teaching Assistant at UC3M

I am mainly teaching security-related courses. Currently, I am teaching Mobile Device Security since 2013, among others.

Starting from 2014 we are opening a new Master in Cybersecurity. I will be coordinating and teaching the following subjects:

  1. Analysis and Engineering of Malware.
  2. Advanced Persistent Threats and Information Leakage.

More information about my teaching can be found here.
