Platform: drones and UWB (since 2016)

Studying formation and swarm flight based on inter-drone distance measurement over Ultra-Wide Band.

• Built an Ultra-Wide Band (UWB) measurement module
  (PCB design, and driver for the ChibiOS embedded OS)
• Studied UWB distance measurement for steering drone swarms [9]
• Adapted the Crazyflie drones' firmware for better stabilisation (anti-windup)
• Developed a network protocol computing and exchanging inter-drone distances [8] [10]
• Ported the code to the Mynewt and Zephyr embedded OSes, and to the Crazyflie microcode (on FreeRTOS)
• Built, on Unix, a simulation of the UWB network layer to ease debugging
• Wrote a library (bitters) simplifying access to GPIO, SPI and I2C peripherals from Linux
• Built an Ultra-Wide Band sniffer out of a Raspberry Pi and a DWM1000 chip
• Implemented an I2C slave interface serving distance measurements to a Raspberry Pi

Platform: TurtleBot (2016)

A set of TurtleBots controllable through ROS.

• Developed communication between ROS processes [7]

Priva'Mov [LabEx IMU / ANR] (2015-2016)

Development and deployment of a crowdsensing platform collecting mobility traces from a panel of smartphone-equipped users, and collection campaigns feeding cross-disciplinary projects.

• Took part in the meetings defining the data-collection needs
• Designed the collection backend, with alerting and reporting (over 300 million records under management) [6]
• Designed an analysis and simplification tool for the collected GPS traces that cut the dataset by 95% (implemented the Douglas-Peucker and Reuman-Witkam algorithms; adapted radial-distance simplification to detect stationary zones while keeping the interpolation property)
• Built a web module for visualising and exploring GPS traces
• Applied it to WiFi-based localisation [5]

Sense City [EquipEx / ANR] (2014)

A lightweight experimentation platform for deploying wireless sensor networks, designed above all to be easy to move and redeploy in the field.

• Designed an infrastructure, with a web interface, for deploying microcode onto embedded sensors and preserving their execution traces. (Used in demonstrations at the French Senate and the 5i forum.)

WifiScan (2011)

• Wrote an Android application collecting WiFi signals and GPS coordinates

Aoraï (2010)

A Frama-C plugin annotating a C program from LTL formulas so its temporal properties can be verified.

• Implemented, in OCaml, an automata description language making constraints simple to state.

Grid5000 [ACI Grid] (2004-2005)

Construction of a grid experimentation platform, from network protocols up to applications, aiming to connect and manage 5000 nodes spread over 9 sites across France.

• Technical lead for the Lyon site
• Cross-site collaboration on the technical choices
• Systems and network administration of Grid5000 Lyon
• Configuration of core network equipment: Extreme (BlackDiamond 8810), Foundry (EdgeIron), Cisco (Catalyst)
• Deployed the hardware (the 250 Lyon nodes) and software infrastructure
• Took part in writing the calls for tender, analysing the bids, designing the test plans and accepting the equipment

Amarrage [RNRT] (1999-2001)

Definition, design, implementation and validation of the then new concept of active networks, through a nationwide test bed and the study of two classes of applications: multimedia and network management.

• Implemented the ANEP protocol in the Linux kernel and created its user API [1] [2] [3]
• Deployed the ANEP-based active-network platform nationwide

Other activities

• Created a 4-hour lecture and a 3-hour tutorial on file systems and ZFS
• Six-month journey across South Asia (July 2014)
