Cybersecurity researcher.

Currently, I am an assitant professor within the Cybersecurity group at Delft University of Technology where I carry out research on cybersecurity governance, cyber-crime and security metrics. I am also passionate about data science and network security.

RESUME

Employment

Assistant Professor2016 - Present

Cyber Security - TU Delft

Conducting research on cyber security withint the Multi-Actor systems department.

Postdoctoral researcher 2014 - 2016

Economics of Cybersecurity

During this post-doc I conducted large-scale measurements to create reputation metrics for Internet intermediaries. I was part of a 20-person team working on worldwide measurements of ISP performance in the fight against botnets and carrying our ground-breaking work into new markets. We developed measurements and metrics for the hosting market, mobile networks, DNS and financial services.

Postdoctoral researcher 2013 - 2014

Information Security Group (UPC)

My past research focused on two areas that I believe are crucial to the success of future of wireless systems: Security and Multimedia. Today’s wireless systems fall significantly short of providing satisfactory solutions to these issues.

RESEARCH

Information Security

As assistant professor, my research involves studying economic factors that shape network and information security. In particular, my research focuses on developing and analyzing economic models of incentives in the presence of various types of security threats. This research is essential as today's growing number of information security problems have more to do with economics than they do with with technology. Technological mechanisms for securing computer systems are widely available, yet computer users and administrators typically underinvest time and resources into security, both relative to what they say is important to them, and relative to what might reasonably be considered socially optimal. Moreover, this type of underinvestment can happen even while individual decision-makers are behaving ratio- nally, relative to their local environment. The aim of my research, alongside others in the economics of information security community, has been to understand this phenomenon using the tools of economic modeling and game theory. My ongoing research in this area aims broadly to identify, analyze, and suggest remediation mechanisms for practically-motivated systems with counterproductive incentive structures I am committed to raise the profile of Cyber Security among businesses. I love to help other skilled engineers develop themselves and discover the world of Cybersecurity.

Secure ubiquitous computing

My previsous research focused on (i) the design and implementation security measures for wireless networks and (ii) the security and user privacy in ubiquitous mobile computing. The goal of my research is to design, analyze, and implement robust protocols that improve mobile access in diverse networks including vehicular, peer-to-peer and WiFi infrastructure networks. The protocols should overcome a wide range of disruptions under extremely unpredictable environmental conditions. Additionally, my work seeks to decentralize the security services. Although decentralization can overcome the limitations of centralized approaches in large and dynamic systems, it comes with price. One of my research questions is what is the price of decentralization and how it trade-offs with its benefit.

Vehicular Networks

Nowadays, cars are essentially computers on wheels. Whereas up till now cars have always relied on information they could autonomously gather, it is expected that the emergence of communicating vehicles will allow safer, more efficient, more comfortable methods of transport in the future.

My research is focused on the analysis of the IEEE 1609 protocol. This protocol mandates use of a Control Channel and Service Channels. In a setup with a single radio, a node periodically visits the Control Channel to exchange "safety critical" information, and can arbitrarily use other channels in the meantime. On a channel, the CSMA/CA mechanism defined by IEEE 802.11 is used. These schemes and their interaction on eachother and with a wide variety of applications is still subject of research.

Future research

My primary research interests lie in information security, foundations of mathematics and com- puter science, and in data science education. I also have much broader research interests where collaboration is involved. In recent years, I have enjoyed opportunities to collaborate productively with researchers outside my primary areas of interest, and I expect to continue to do so in the future.

Teaching

Massive Online Courses

During November 2014 until March 2015, I was part of the staff that developed and taught the first Economics of Cybersecurity massive open online course.

Undergradute Courses

During the 2012/2013 academic course, I taught at Escuela Superior de Telecomunicacion de Barcelona (ETSETB) in the Telecommunication Engineering graduate program.

Graduate Courses

Since 2015, I am imparting several courses within Delf University of Technology:
  • Mathematical modelling and society
  • Economics of cybersecurity
  • Intra- and inter- organizational decision making
During the 2012/2013 academic course, I taught at Universtitat Politècnica de Catalunya (UPC) in the Telematics master program.
