Bio
Alexis Germain
As Lilian's teammate in Safran Aircraft Engines for a few years, I've benefited from his creative problem-solving, for which he has always been able to propose innovative solutions resulting in numerous international patents. As a colleague, Lilian is incredibly generous with his time and expertise, which includes expert-level in mechanical design, strong communication skills with our customers such as product manufacturers and supply chain teams. I have to say that his humor and good nature make the challenges to be tackled much easier on his team.
