Background & interests

Professional background

As an engineer with a PhD in computer vision and a technical manager, I have worked on projects combining AI, software development, cloud infrastructure and medical software. My role has involved connecting user needs, technical decisions, solution development and validation requirements.

From 2020 to 2025, I worked at SURGAR, first as an R&D Engineer and then as Data Science Technical Manager. I led computer vision and machine learning projects, managed technical teams and helped design a software ecosystem spanning clinical data collection and anonymisation through to its use in the cloud.

This experience also involved integrating AI models into production software and addressing the quality, traceability and validation requirements of a regulated medical environment.

Outside work

I have a longstanding interest in new technologies, robotics and energy. Outside work, I particularly enjoy strategy and management games, chess, independent video games and cinema. I also read a lot of comics, manga and novels, with a strong preference for science fiction.

I also enjoy travelling, hiking and racket sports. Originally from Béthune, I have lived in several French cities and spent time studying and working in Japan, notably in Yokohama, Fukuoka and Tsukuba. These experiences have fostered a lasting interest in the country and its culture.

About

Working with others

Working across disciplines

I enjoy teamwork, both as a developer and as a manager. Discussing different perspectives helps me assess technical choices and better understand project needs. I like connecting research, development and other teams.

Sharing knowledge

Making science accessible matters to me. I take time to explain technical concepts and adapt my explanations to the person I am talking to. I also enjoy discussing how technologies work and how they evolved, both at work and outside it.

Building working relationships

I value listening, regular conversations and good relationships between colleagues. As a manager, I support individual development and the sharing of skills within the team.

SURGAR

Clermont-Ferrand

Data Science Technical Manager

  • Led software, data and AI projects: defined roadmaps, made architectural decisions, prioritised activities and monitored development progress. Managed teams, recruited new members and supported their growth.
  • Designed and deployed a software ecosystem using C++/Qt, Python/Flask and PHP/Symfony, with Google Cloud Platform infrastructure for collecting, anonymising and securely processing clinical data.
  • Coordinated with clinical, Product, software development, Quality/Regulatory and cybersecurity teams: gathered needs, translated them into functional and technical requirements and resolved competing priorities.
  • Developed a Python/PyTorch framework for model training, validation and integration: reproducible pipelines, version control, ONNX export and CI/CD integration.
  • Oversaw the development and integration of models for segmenting and classifying anatomical structures in laparoscopic videos, MRI and CT scans.
  • Defined AI component validation strategies covering performance, traceability, risks and documentation. Wrote procedures for Data/AI activities and medical data management under IEC 62304 and ISO 13485.
