Mission

Bioelectronics integrates principles of electrical engineering to biology, medicine and ultimately health. My lab challenges and seeks to advance our fundamental concepts in man-made electronic systems applied to biology. Specifically, the focus is on designing and manufacturing electronic devices with mechanical properties close to those of the host biological tissue so that long-term reliability and minimal perturbation are induced in vivo and/or truly wearable systems become possible.
We use fabrication methods borrowed from the MEMS and microelectronics industries and adapt them to soft substrates like elastomers. We develop novel characterization tools adapted to mechanically compliant bioelectronic circuits. We evaluate in vitro, in animal models and ultimately on humans our soft bioelectronic interfaces

Biography

Stéphanie P. Lacour is full professor at the School of Engineering at the Ecole Polytechnique Fédérale de Lausanne. She received her PhD in Electrical Engineering from INSA de Lyon, France, and completed postdoctoral research at Princeton University (USA) and the University of Cambridge (UK). She joined EPFL in 2011. She was the founding director of EPFL Neuro X institute – a new interschool department focused on interdisciplinary and translational neuro-research located at EPFL-associated campus – Campus Biotech in Geneva. Since 2025, she is EPFL Vice-President for support to Strategic Initiatives.
