Summary
🤩
Rockstar🎓
Top SchoolAndrás Retzler is a PhD-postdoc hybrid engineer combining 26 years of hands-on embedded and FPGA design with recent academic research in nonlinear system identification and hybrid physics–data models. He founded and is the primary maintainer of widely used open-source SDR projects like OpenWebRX and CSDR—the latter having been used in high-profile contexts such as NASA tracking—demonstrating full-stack capability from VHDL/Verilog and bootloader work on Zynq to Python web UIs and DSP tools. His background spans custom PCB and firmware development across AVR, PIC and ARM, high-level FPGA synthesis, and practical experience with Xilinx toolchains. Currently at D2LAB (UGent) after a joint PhD at KU Leuven and BME, he blends rigorous research with production-grade engineering and a knack for turning complex signal-processing theory into deployable systems.
