• Process and extract features from experimental signals to build machine
learning datasets;
• Train and optimize regression models (e.g., XGBoost) for ion type and
concentration prediction;
• Perform result visualization, performance evaluation, and prepare technical
project reports.

Qualifications:

1. Master’s degree or above in Electronics, Signal Processing, Communications, Computer Science, or other related engineering fields;

2. Proficiency in Python programming and common data processing libraries;

3. Solidunderstanding of signal processing theories and methods (Fourier Transform, Wavelet Transform, filtering, and feature analysis);

4. Familiarity with experimental instrument control and data acquisition (e.g., AWG, PicoScope);
