BOISSY-ST-LÉGER

En résumé

Mechanical Engineer with Electrical core,

I graduated from the “Ecole des arts et métiers ParisTech” (Paris, France) and “The Georgia Institute of Technology” (Atlanta-USA) with a Master of sciences in Mechanical Engineering.

I am focused on the bio-technologies and more specifically in:

Real-time and streaming based health monitoring systems, Analog & Digital electronics. Signal processing and filtering (Embedded DSP filters). M2M Wireless network programming (embedded TCP/IP stack, .Net networking), Radio-Frequency systems integration 2.4GHz, 800MHz-2100MHz (Bluetooth, WiMax, GSM-2G/3G/UMTS). Ultra-Portable, battery operated systems (mAH to AH range) with energy harvesting capabilities.

  • Troxler Electronic Laboratories - Intern

    2011 - 2011 The research project was about the design of a novel technique for testing mechanical properties of soil based materials, including the design of its associated apparatus.

    We built a FEM model of the system, which served as a support for numerical simulations using COMSOL. Conducted simulations combined with laboratory observations gave a clear insight of the mechanical behavior of the system, which led to the foundations for the design of a low frequency, multi-resolution testing instrument. The instrument along with its associated methodology showed a clear reading of the segregated wave’s velocity between, compression, shear and Rayleigh waves within the medium, providing a mean for back-calculating soil’s physical characteristics.

    The instrument was successfully tested during a field campaign conducted at the military site of the Army Corps of Engineers, New Orleans.

    Skills and techniques: Data acquisition systems (IAR for ARM7), Data mining and analysis (Matlab), Mechanical system design (CAO-Catia) and supervision of fabrication in house, IEPE accelerometers analog front end design and instrumentation electronic chain.
