Dr Marcin Kielar obtained his PhD in organic electronics from the University of Bordeaux in 2016, under the supervision of Dr Lionel Hirsch, for work conducted in collaboration with ISORG, a company that has pioneered printed organic photodetectors (OPDs). In early 2017, Dr Kielar joined the Queensland Brain Institute at the University of Queensland in Australia as a postdoctoral research fellow in the laboratory of Prof Pankaj Sah. He applied his considerable expertise to the design, fabrication, and characterization of organic multifunctional optoelectronic devices (OPDs and OLEDs) for applications in neuroscience (neural recordings and imaging), near-infrared sensing, and robotics (electronic skins). He also pioneered the development of smart wearable sensors for the optimization of therapy in patients with neurological movement disorders. His highly multidisciplinary and collaborative research led to multiple international awards. In late 2024, Dr Kielar moved to the University of Angers in France to start his new role as a Junior Professor in organic electronics at the MOLTECH-Anjou laboratory.
