Romain Mottier

Former mechanical engineer (MSc), I specialised in applied mathematics (PhD) — I help companies solve complex technical problems where simulation, computation, and engineering meet.

With several years of experience in numerical modelling and scientific software development — through both a PhD at CEA and my current postdoctoral research at the University of Basel — I work with engineering teams, R&D departments, and industrial partners to turn difficult technical challenges into practical, reliable solutions.

Beyond scientific computing, I also help businesses of all kinds automate repetitive or time-consuming tasks using AI, and validate AI-generated or AI-assisted results — simulations, calculations, technical specs, or any other output — before they inform critical decisions.

Whether it is developing custom numerical solvers, improving simulation workflows, accelerating legacy scientific code, analysing complex datasets, automating business processes with AI, or auditing AI-assisted work, I provide both strategic insight and hands-on execution.

Available for part-time consulting, technical collaborations, and high-value problem-solving assignments — on-site in the Greater Basel Area or fully remote.
