About Me

After a multidisciplinary formation in Transport Enginnering and in Physics (Machine Learning, Statistics, Complex Systems), I completed a joint PhD on the retrieval of Link-Origin-Destination matrices from Bluetooth data, within the Smart Transport Research Centre (Queensland University of Technology, Brisbane) and the SISYPHE department at Ecole Normale Supérieure de Lyon.
I am now working at the ZHAW as a post-doc, searching innovative solutions for industrial system predictive maintenance.
When I am not digging databases, I like to go out for some fresh air, climbing or hikking, to play volleyball or to jump in the water and say hello to the marine life.

    PhD in Physics and Civil Engineering May 2013 - July 2016

    Exploring the opportunities of Bluetooth data for the retrievals of travel informations in urban networks with a particular focus on:

    • Understanding, cleansing and analysing of the Bluetooth data collected by 500+ scanners in Brisbane.
    • Developping methods to take advantages of data stemming from detectors with identification abilities:
      • For retrieving trajectories from a discrete network of detections.
      • For estimating Origin-Destination matrices in urban context.
      • For Extending the concept of ODM to more comprehesive tools containing more information on traffic behaviour (Link Specific ODM).
    • Developed a optimisation method for traffic inference in urban context.
