Why a career in tech?

At first, almost by chance. I enjoyed mathematics and physics, so I naturally moved in that direction. Over time, I discovered that engineering is really about solving real-world problems. What I love is turning complex challenges into practical solutions. There is always a new problem to tackle, which means there is never a dull day.

Your professional experience?

While studying mathematics and physics in prépa, I quickly realized that I missed chemistry. That led me to join ENSIC, a chemical engineering school in Nancy, where I specialized in process engineering and energy-related technologies. After graduating, I joined Air Liquide in Research & Development and have since built my career around industrial innovation, operations and energy-transition technologies.

Your first experience with technology

My first internship was at a large chemical production site, working alongside operators on a 24/7 production unit. It was an eye-opening experience: discovering the scale of industrial installations, understanding what it takes to keep a plant running safely every day, experiencing true teamwork—and even sharing midnight meals with colleagues.

What do you do today, and why?

Today, I am an expert within Air Liquide’s Industrial Direction, focusing on hydrogen production and carbon capture technologies. I support the industrial deployment of innovative solutions, from CO₂ capture on industrial flue gases to ammonia cracking technologies. I also help implement best practices to ensure our operating plants are safe, reliable and efficient. What motivates me most is seeing innovative technologies move from concept to industrial reality.

Your strengths in this role?

I would say my ability to simplify complex situations, my pragmatic mindset, and my capacity to connect people from different backgrounds, disciplines and cultures around a common goal.

Past challenges, failures and disappointments?

Every career move has been both a challenge and a tremendous learning opportunity. One of my biggest challenges was becoming a team leader for the first time. I initially thought I needed to have all the answers – which was isolating. I soon realized that leadership is not about knowing everything—it is about building the right network, asking for help and learning from others. Of course, I made mistakes along the way, but many of those mistakes became valuable lessons.

Best moments, successes you’re proud of?

Early in my career at Air Liquide, I had the opportunity to contribute to the development of a new hydrogen production technology. It was an incredible team adventure, from operating an industrial-scale demonstration unit to securing the first commercial contract. Seeing years of work turn into a real industrial project was both rewarding and inspiring.

People who helped, influenced -or made your life difficult?

I have been fortunate to work with experienced experts and mentors throughout my career. They shared not only their technical knowledge but also their ways of thinking, problem-solving and collaborating. They helped me grow both professionally and personally. Looking back, they have had a lasting impact on the engineer I am today.

Your hopes and future challenges?

I hope to continue contributing, in my own way, to the fight against climate change. Developing and deploying technologies that reduce greenhouse-gas emissions is both a professional challenge and a personal motivation.

What do you do when you don’t work?

I read a lot—some would say far too much. I also spend a great deal of time exploring the world through my young son’s endless curiosity. With him, every question becomes an adventure and every walk turns into a discovery.

Your heroes -from History or fiction?

Fantômette, the heroine of a series of French children’s books that I read growing up. She is fearless, resourceful and clever.

A saying or proverb you like in particular?

“Science without conscience is but the ruin of the soul.” — François Rabelais.

A book to take with you on a desert island?

The Accursed Kings by Maurice Druon. It is one of my favourite historical sagas, and a desert island might finally give me the uninterrupted time needed to read it again.

A message to young female professionals?

Don’t wait until you feel 100% ready—nobody ever does. Be curious, ask questions, trust yourself and dare to take opportunities. Your perspective, your ideas and your talent are needed more than you think.
