The use of organic mixed ionic-electronic conductors (OMIECs) for (bio)electronic devices has grown substantially in the last 20 years, with new materials and device concepts pushing performance forward. The inclusion of both electronic and ionic carriers makes an understanding of transport phenomena however challenging, and the materials design rules and device models are still actively being developed.
Interdisciplinary discussions and research are therefore crucial in developing structure-property relations and enabling rational design of high-performance materials and devices. This symposium aims to bring together speakers spanning from materials synthesis and design to characterization and device engineering to discuss a holistic view of OMIEC materials development, with the final application in OECTs in mind.

Tom van der Pol is a Marie Curie fellow at the Laboratory of Organic Electronics within the Linköping University in Sweden. His research interests revolve around characterization of novel semiconductors, currently focused on organic mixed ion-electron conductors. He conducted his PhD research at the group of René Janssen studying optical characterization of thin film organic and perovskite semiconductors for solar cell applications.
Olivier joined ICPEES as independent young researcher (Chargé de Recherche) in February 2023. His interests are in understanding the chemical and electrochemical doping mechanisms of highly anisotropic and porous organic semiconductors for bioelectronic and thermoelectric applications. A physicist by training, he obtained his MSc in Nanoscience and Engineering Physics at the Grenoble Institute of Technology (Phelma, France) in partnership with Imperial College London (UK). To better understand the molecular design of the materials he was studying, he completed a PhD at Université Grenoble Alpes/CEA Grenoble (France) with Dr. Renaud Demadrille from 2016 to 2019. He focused on the organic synthesis of n-type polymers and their doping for thermoelectric and photovoltaic applications. From 2020 to 2023, he developed his skills in time-resolved spectroscopy and data analysis during a post-doctoral stay in the FemtoMat group of Prof. Natalie Banerji at the University of Bern. Notably, he improved the electronic performance of organic electrochemical transistors (OECTs) and identified energetical and morphological factors limiting the (de)doping kinetics of the polymer channel during device operation.
C. Daniel Frisbie is Distinguished McKnight University Professor of Chemical Engineering & Materials Science (CEMS) at the University of Minnesota. He was Head of CEMS from 2014-2024. He obtained a PhD in physical chemistry from MIT in 1993 and was an NSF Postdoctoral Fellow at Harvard in 1994. His research focuses on materials and processes for large area printed electronics and photonics. Additional topics include organic semiconductors and devices, electrochemical transistors, molecular electronics, and scanning probe microscopy.
Dr. Esma Ismailova, Associate Professor with an HDR at Mines de Saint-Etienne (EMSE), France. She received her BSc. in Physics and a Master’s degree in Polymer Science at Strasbourg University in France, where she also completed her PhD in Chemistry and Chemical Physics sponsored by STMicroelectronics. She then joined the Laboratory for Organic Electronics at Cornell University, NY, USA as a PostDoc, studying the interface between biology and electronics. In 2010, she joined EMSE to establish a micro-fabrication platform for soft biocompatible neural implants at the Bioelectronics Department. Her current research interests focus on the design and fabrication of novel organic electronic devices for multi-parametric sensing. Dr. Ismailova has initiated national and international collaborations to develop organic wearable devices on textiles for healthcare.
