Valentin Poirot

IoT and Embedded ML Researcher - Doctoral Candidate

Kiel University, Germany & Chalmers University of Technology, Sweden



Systems Researcher with 4+ years of experience in low-power wireless communication for IoT (Bluetooth Low Energy and Mesh, IEEE 802.15.4).
I also design Machine Learning solutions for constrained platforms (Tensorflow Lite for Microcontrollers, CMSIS NN, Tiny ML). Proficient in C, Python, Tensorflow, and embedded operating systems (Zephyr RTOS, Contiki-NG).
Team-oriented, I led 10+ B.Sc/M.Sc theses and projects during my PhD.
Erasmus Mundus alumnus, I studied and worked in four countries.
Final year PhD Candidate, defense target is September 2022.
