Cheer3142/README.md
Patcharadanai Sombatsatien: instrumentation, signal processing and ML. Oscilloscope trace of a LiDAR return signal.

I build the whole measurement chain: the optics and electronics that sense, the firmware that acquires the signal, and the math and models that turn it into an answer. I'm currently working on AirGradient air-quality monitor firmware. Before that I worked on atmospheric LiDAR, telescope prototypes and FPGA links to RF hardware, and I research domain adaptation for open-vocabulary segmentation.
