Short biography I am a post-doctoral researcher at TU Delft and a member of the Economics of Cybersecurity group analyzing large-scale Internet measurement and incident data to identify how providers of Internet services deal with security risks and incidents.

I was a visiting scientist at the Yokohama National University in March 2015.

Between February 2013 and May 2014, I was post-doctoral researcher at Rutgers University and a member of the Fefferman Lab investigating bio-inspired algorithms in distributed anomaly detection systems.

I received my Ph.D. in Computer Science from the University of Joseph Fourier in Grenoble. Between October 2009 and December 2012 I was a member of the Drakkar group at LIG Lab.

Until 2012 I was an active member of the group of the researchers within the COST Action IC0703 "Data Traffic Monitoring and Analysis (TMA)" dedicated to traffic measurement and network attack detection in the Department of Telecommunications in AGH University of Science and Technology.

I received my M.Sc. in Electronics and Telecommunications from the AGH University of Science and Technology in 2009.

In 2009 I was an invited researcher student in Network Management and Optimal Design Laboratory (NETMODE) at National Technical University of Athens (Short Term Scientific Mission within the COST Action IC0703).

Between October 2007 and January 2008 I was an exchange student in Department of Electrical and Communications Engineering (Communications Laboratory) at Aalto University (former Helsinki University of Technology), Helsinki, Finland.

  • [2016.05.05] I will give a talk about the Clean Netherlands project titled: "Tackling Internet pollution using science and law enforcement" at a cybercrime conference organized by the Cambridge Cloud Cybercrime Centre on Thursday, 14th July 2016.
Scientific interests I am interested in areas related to network security:
  • Network traffic measurement, analysis, and classification
  • Distributed detection and confinement of abnormal activities in network traffic
  • Reputation metrics to improve intermediary incentives for security
