About us

What myBIOS is all about

is a Biotech company founded in 2020 by Claudia Rinnofner. We focus on the production of protein-based (biological) molecules with unique physical and biochemical properties. We are located in Graz at the Zentrum für Wissens- und Technologietransfer in der Medizin (ZWT), Neue Stiftingtalstraße 2 | 8010 Graz, Austria.

Claudia Rinnofner, DI Dr. earned her PhD at Graz University of Technology (TUG) in the research group of Prof. Anton Glieder at the Institute of Molecular Biotechnology. Her doctoral thesis was devoted to the expression of recombinant proteins in Pichia pastoris employing synthetic promoters. Following her PhD she worked at ACIB GmbH (Austrian Centre of Industrial Biotechnology) in an industrial multi-firm project. Claudia Rinnofner has more than 15 years experience as a scientist, working with Pichia pastoris and strain engineering including the recombinant expression of various heterologous proteins.

Sandra Flecker, M.Sc. studied Molecular Biology, Biochemistry and Molecular Biomedicine at the University of Graz. She joined myBIOS in late 2021. Prior to it she was working in a diagnostics company. In the last 2 years she gained experience in the field of Pichia research and development and is currently working as lab-Team leader at myBIOS.

Alexandra Deibuk studied Molecular Biology in frame of her bachelor’s degree and is currently completing her master studies in Biochemistry and Molecular Biomedicine as well as Biotechnology. She did her master thesis at Graz Technical University in collaboration with myBIOS (master thesis in review). She is currently working at acib.

Azra Bjelic studies Molecular Biology and is working part-time at myBIOS.

Elma Zukancic studies Molecular Biology and is working part-time at myBIOS.
