How I work

Every project is different. Rather than applying predefined solutions, I start by understanding the experimental problem, the available instrumentation and the expected results.

My role is to identify the origin of the difficulty, propose practical solutions and help implement them, whether the problem concerns scientific instrumentation, measurement techniques or specialized software.

Whenever possible, I privilege simple, robust and durable solutions.
