Biographical Sketch

Mathias Polz was born in Wolfsberg, Austria, in 1994. Since his school days at the Mössingerstraße Technical College (HTL), through his civil service as a paramedic with the Austrian Red Cross, and finally his university studies, he has been continuously involved in biomedical engineering. He completed his Bachelor’s degree in biomedical engineering at Graz University of Technology in 2020 and obtained his Master’s degree in the same field in 2021. He is currently pursuing his doctorate with a focus on the development of wireless stimulators for the optoelectronic activation of excitable cells and tissues. His research interests include optoelectronic neurostimulation, materials science, and mechanobiology, focusing on the integration of tissue-inspired materials and stimulation techniques to interface with biological systems. In addition to his research, he is actively involved in teaching and mentoring, e.g., in the Sindbad Program – mentoring for young people in Graz, and participates in various scientific and public initiatives, including presentations at the International Student Congress and various bioelectronics conferences. He also gives lectures at events within the framework of Pint of Science Austria and later became a member of the organizing team.
