Gaëtan Fichet de Clairfontaine

From astrophysics to data.

Building pipelines, models, and clarity.

About me

With a PhD in astrophysics, and years of research experience, I am now applying scientific rigor to data science and engineering. I build robust data foundations, run practical analyses, and communicate not just results — but the assumptions and trade-offs behind them.

I'm open to junior / early-career roles in data science and engineering.

Technologies & approaches I use
Core
PythonSQLpandas, NumPyscikit-learn (ML)Visualization (Plotly, Matplotlib)
Exploring
PyTorch (transfer learning)Docker (packaging)HPC / SLURM (from research)

Research, in one minute

I study how energetic outflows from extreme objects shape galaxies. Think of it as "weather models" for cosmic jets: we simulate, compare with real observations, and keep only what survives the data.

Recruiter takeaway: I build models, test them against data, and ship code and documentation your team can actually use.
