Summary
🤩
Rockstar🎓
Top SchoolSören Tempel is a Postdoctoral Researcher and embedded systems engineer with 13 years’ experience combining academic research and hands-on IoT development in Germany. He holds advanced degrees from the University of Bremen and progressed from student tutor to PhD-level researcher, bridging theory and implementation across multiple projects. Sören has contributed to the well-known RIOT OS, fixing critical bugs (integer overflows, memory leaks, out-of-bounds access) and adding board- and peripheral-level support such as I2C for the bluepill. His career blends roles at DFKI and the University of Bremen with recent postdoc work at Technische Universität Braunschweig, reflecting a strong focus on dependable low-level networking and embedded software. Colleagues value him for finding subtle memory and networking defects that improve system robustness, a skill that complements his research on resource-constrained systems. Pragmatic, detail-oriented, and academically grounded, he excels at turning research insights into production-grade embedded code.

Contributions summary:Sören contributed to the RIOT operating system by fixing an integer overflow in the CBOR library. They added support for the bluepill board, including peripheral configurations and board-specific hardware initialization. Additionally, the user implemented I2C support for the bluepill, copied from the nucleo-f103 board, and fixed various bugs and memory access issues within the networking stack, including fixing out-of-bounds buffer access, integer underflows and memory leaks within different network modules such as gnrc_tcp, tftp and asymcute.
