Back to original languageAbout Aurélien
I am a data analyst and signal processing specialist, with a strong background in GNSS reflectometry and scientific data analysis.
I conducted doctoral research in geophysics focused on developing Python algorithms based on advanced filtering methods, particularly Kalman filtering, to extract relevant information from complex and noisy signals.
My approach combines scientific rigor with technical pragmatism: I transform complex datasets into actionable insights using robust, automated, and documented tools.
I primarily work with Python, NumPy, pandas, SciPy, and Matplotlib, and I design custom scripts for:
- cleaning, filtering, and merging sensor data (SNR, GNSS, time series);
- modeling and statistical analysis of physical phenomena;
- clear and aesthetically pleasing visualization of results;
- automating environmental data processing pipelines.
I can assist you with projects in:
- data analysis and visualization (environment, geosciences, oceanography, engineering);
- physical signal processing (GNSS, sensors, remote sensing, time series);
- developing custom Python tools for your scientific or industrial analyses.
What sets me apart:
a dual expertise in data science and signal physics, a clear and structured approach, and the ability to make complex phenomena clear and actionable.
If you are looking for a profile capable of understanding your data, structuring it, and producing reliable and visually compelling results, let's discuss your project.
