William Hochart
I study mechanical engineering at Arts et Métiers, one of France’s oldest engineering schools. I am drawn to machines at every scale, from a shoulder implant to a plasma thruster, and I see engineering as a craft where technical rigor and creativity meet.
My current team projects span biomechanics, where we are redesigning a glenoid implant so that it resists loosening, and aerospace propulsion, where we are studying an air-breathing plasma thruster for CubeSats. Before that, I spent a year recovering speech from noisy recordings with digital filters and spectral methods I wrote from scratch in Python.
Across these projects I follow the same progression: study the literature and the physics, build a model, then confront it with tests and real signals.
Image notes: 1. It’s the Arts et Métiers students’ formal uniform: a navy-blue outfit modelled on a French Navy officer’s uniform, a nod to the school’s military past. 2. This is Arts et Métiers' Metz campus. I studied there for my first year in the school before moving to Paris.TitleWilliam HochartMechanical engineering student
