Anomaly detection in Internet traffic, Automated classification of Internet traffic/hosts.


  • Ph.D. The Graduate University for Advanced Studies, Tokyo Japan, September 2011

    Concentration: Increasing reliability in Internet traffic anomaly detection, Combining Internet traffic anomaly detectors, Automated classification of network traffic

    Investigated the strengths and weaknesses of several unsupervised detectors that are identifying backbone traffic anomalies, namely abnormal usages of Internet resources (e.g. worms, DoS attacks, network scans). Developed an unsupervised learning methodology to combine diverse anomaly detectors and to allow a high detection rate for a variety of traffic anomalies. Evaluated the proposed method using 10 years of backbone traffic, and made the results publicly available and updated daily in order to assist researchers in validating upcoming detectors against emerging anomalies: MAWILab (implementation in C++ and Python).

  • M.Sc. Computer Science, Joseph Fourier University, Grenoble France 2008

    GPA: 15.394/20 (Top 10%)
    Concentration: Anomaly detection in Internet traffic, Internet traffic Visualization

    Six month internship at Fukuda Lab., National Institute of Informatics, Tokyo. Developed in C++ a visualization tool that monitors backbone traffic at different scales and highlights traffic anomalies. Identified visual patterns characterizing anomalies in general. Designed and implemented a pattern-based anomaly detector that automatically reports traffic anomalies.

  • Exchange student at Concordia University, Montreal Canada, September 2006 - May 2007

    Concentration: Fault tolerant distributed systems

  • B.Sc. Computer science, Joseph Fourier University, Grenoble France 2005
  • DEUG MIAS (General Diploma of Mathematics and Computer Science Applied on Science), Joseph Fourier University, Grenoble France 2004


Work Experience

  • Post Doctoral Researcher (JSPS Fellowship), The University of Tokyo - Esaki Laboratory, November 2011 - October 2013
  • Programmer Analyst, DFInformatique, July 2007 - December 2007

    DFInformatique develops custom software solutions for a wide range of customers.

    Participated in the design, implementation, validation and installation of a savings account system according to the customer needs (Malakoff-Mederic). Implemented a tool to migrate the data (employees banking records of more than 7000 companies) from the previous Oracle-based system to the new HyperfileSQL-based system. Developed accounting features in the new system and the web interface for customers access (implementation in Windev, Webdev).

  • Intern, INRIA Rhone-Alpes, April 2006 - August 2006

    Worked on fault tolerant distributed systems in the SARDES team. Designed and implemented an extension allowing the component model Fractal to deal with component partially available and to recover them (implementation in Java).

  • Tutor, Joseph Fourier University, October 2005 - June 2006

    Supervised candidate students of the C2i level 1 (the French IT and Internet National Certificate).

Awards and Scholarships

  • The National Institute of Informatics Scholarship

    Awarded for a 3 years PhD course at the Graduate University for Advanced Studies, Tokyo Japan.

  • Memorandum of Understanding Grant from the National Institute of Informatics

    Awarded for a six months internship at the National Institute of Informatics, Tokyo Japan.

  • Magister from the Joseph Fourier University

    Magister is a highly selective three-year course offered by prestigious French universities to the highest-ranked students.

  • Mobility Scholarship from the French Ministry of National Education, Advanced Instruction, and Research

  • Rhone-Alpes Explora Scholarship for International Mobility

    Both awarded for a one year exchange program at Concordia University, Montreal Canada (2006-2007).


  • Member of the WIDE Project

    Actively contributing to the MAWI (Measurement and Analysis on the WIDE Internet) working group. In charge of the MAWILab project (http://www.fukuda-lab.org/mawilab/) that is maintaining an automatic labeling of the anomalies appeared in the MAWI traffic archive (repository containing 10 years of backbone traffic). Presented twice recent advances in the MAWI working group at the CAIDA-WIDE-CASFI workshop.

  • JSP-ANR and JSPS-CNRS Collaboration

    Collaborating since 2008 with Japanese and French institutions such as the CNRS and the University of Tokyo. In particular, I am working closely with physicists from the CNRS that have a strong theoretical background of several statistical approaches that are applied in anomaly detection.
