I have been working in the laboratory business for more than 9 years. After a couple of years in consulting, I joined Eurofins, the world leader in laboratory testing in 2014 (CAC40 company, 55,000+ employees in 54 countries). During my career at Eurofins I successively envisioned, implemented and staffed two cross-functional departments of the company: the operational excellence department (15+ internal consultants); and the group processes transformation and digitalisation department (40+ internal consultant, IT development professionals and data management operators).

I initiated and drove large scale programs across the Eurofins group:

  • Generation of >50M€ savings through identification and deployment of best practices (standard times, automation, equipment)
  • Operational performance measurement and associated budgeting (10 key indicators for over 300 business units); deployment of a global costing model
  • Training of Eurofins executives in operational excellence methodologies
  • Complete redesign, development and go-live of an internally developed master data solution for group structure and corporate governance
  • Streamlining of employee lifecycle management process
  • Data strategy definition for group processes management

Early 2022, I created Kallion, to promote operational excellence in the laboratory world and to provide a holistic approach and ecosystem to support laboratories in their operational excellence journey. Through Kallion, I am leveraging my unique experience to bring immediate value to my customers.

I hold an MSc in Applied Mathematics and Operational Management from Ecole Centrale Paris and an MSc in Management from Ecole Supérieure de Commerce de Paris. I am a certified Lean Six Sigma Black Belt from the International Lean Six Sigma Institute (ILSSI).

“I am motivated, results-oriented and passionate about everything related to life sciences, technology and operational excellence. I believe that all approaches must remain human-centred to ensure long-term, sustainable improvement that benefits everyone. Working with me is simple and fluid, I like to go the extra mile for my clients and partners. I am easy going and always curious about others to build lasting working relationships.”
