Industry-Academia Bridge

His combined background in instrumentation manufacturing, applied battery research, and academic research gives him a distinctive perspective on signal analysis for electrochemical systems, bridging rigorous measurement theory with the practical constraints of real-world instrumentation.

PD Dr.-Ing. André Weber is Academic Senior Councillor and leads the Batteries, Fuel Cells and Electrolysis group at KIT's Institute for Applied Materials - Electrochemical Technologies (IAM-ET) in Karlsruhe, Germany.

His research focuses on the characterization and modeling of electrochemical energy converters and storage devices across multiple scales - from the electrochemical and microstructural properties of porous electrodes to the performance and lifetime analysis of engineered cells and the dynamic behavior of full systems, covering both high-temperature fuel cells/electrolyzers (SOFC/SOEC) and low-temperature polymer electrolyte systems (PEMFC/PEMEL) as well as lithium-ion and solid-electrolyte batteries.

Impedance-Based Characterization Across Technologies

A central theme of his research is the use of impedance-based methods to characterize and model electrochemical systems consistently across very different operating regimes, allowing direct comparison between high- and low-temperature fuel cells and electrolyzers as well as battery systems.

Prof. Bilel Hafsi an Associate Professor at ICAM in Lille, France, and a member of the NCM group. He received his Master's degree from the University of Monastir, Tunisia (2012) and his PhD in micro- and nanoelectronics, acoustics and telecommunications from the University of Lille, France (2016). His research background lies in organic electronics, physics, computer modelling, and self-assembly processes, focused on creating new functional materials as building blocks for novel soft-electronic devices.

During his PhD at the Institute of Electronics, Microelectronics and Nanotechnology (IEMN), under the guidance of Prof. Kamal Lmimouni and Prof. Adel Kalboussi, he developed Nanoparticle Organic Memory Field-Effect Transistors (NOMFETs). His more recent work centres on portable, low-cost impedance spectroscopy platforms built around the AD5933 impedance analyzer for gas sensing (electronic nose) and skin bioimpedance measurements, bridging his organic-electronics background with applied impedance-based sensing.
