Matthieu Ems' research focuses on the topic of "Emission and visualization of brake particles applied to rail braking". Work carried out as part of the BREAQ project.

For Matthieu: "With the need to turn to public transport, working in the railway field interested me because it represents a present and a future in our means of travel. The question of ultra-fine particles entering the human body is an increasingly worrying environmental issue. Studying ways of reducing these particulate emissions is therefore of paramount importance." (Source: Interface, the INSA ALUMNI magazine N°149).

Matthieu Ems works in the wind tunnel (link to wind tunnel) at LAMIH, where he has designed a braking rig integrated into a stream of air: it enables flow conditions around the disk to be reproduced. The aim of his work is to identify the thermo-mechanical mechanisms favoring the emission of fine dust. He is also setting up an image analysis protocol to measure dust velocity fields at the contact outlet and downstream of the brake disc.

Matthieu Ems is one of the many talents at LAMIH, the laboratory specializing in transport, mobility and logistics.
