About Me

I am a recently graduated researcher who worked at Inria and Limsi/CNRS at Université Paris Sud.
I was supervised by Tobias Isenberg from Inria and Mehdi Ammi from LIMSI/CNRS.
My main focus lies in the intersection between human-computer interaction and interactive scientific visualization. My focus has been on bridging the gap between several novel interaction paradigms often used in scientific visualization (tactile interaction and tangible interaction). Overall, I am deeply interested by 3D interaction as well as all new interaction paradigms and their applications to specific scientific domains such as medicine or fluid dynamics. To validate my work, I have mainly relied on controlled experiments with users (domain experts or out-of-the-lab participants).

Université Paris Sud

PhD in HCI 2014-2017

I was supervised by Mehdi Ammi and Tobias Isenberg and worked on the building of An Interaction Continuum for 3D Dataset Visualization. With this thesis work, I demonstrated the potential of an interaction continuum for visualization by proposing hybrid interaction paradigms in an easy-to-maintain, easy-to-integrate, and affordable setups. It provides the necessary initial steps for an interaction continuum that will hopefully inspire the creation of more hybrid interaction techniques for 3D data interaction.

Implementation of the HCI and its new components with engineers from Valeo onto a driving simulator. Evaluation of the HCI concept in order to refine the HCI specifications.

Thales Air Systems

Software Developper Intern June 2013 - September 2013

Development of an application which also involved Ecole Centrale Paris in a research project, so as to define a method to help generating and evaluating new antennas' concepts using Bayes Nets, CSPs, and several Java APIs.
The application developed uses Bayes Nets so as to represent and compute all the requirements an antenna should respect. The program allows to add requirements, possible values for different components and/or performance constraints and the user can ask the program to solve the problem which will be done thanks to a fast algorithm.
The application itself allows engineers from Thales to easily create Bayes Nets without ever manipulating them so that they do not require any Bayes Net background to solve their complex problems. Hence, getting the ideal architecture of a new antenna is easier since engineers only need to formulate their problem ( constraints, performance, requirements, available pieces ... ). The resolution of the problem itself is done by the program.
Delivered :

  • Java program with an intuitive interface
  • Complete documentation on the program and some examples
  • Teaching sessions on how to think the conception problems differently so the program can be used

Générale de Santé

Network Engineer Intern Mai 2011 - July 2011

Developing of a network monitoring system based on Nagios and using mainly FAN (Fully Automated Nagios) for a private hospital.
The system had to monitor different machines such as switches, computers, servers or printers and had to be platform independent. Among other things, the internship included working with unix commands, and several network skills such as understanding and using the SNMP protocol for instance.
