About us

What BISY BIOS is all about
BISY BIOS

is a spin-off company of bisy GmbH founded in 2020 by Claudia Rinnofner. We focus on the production of protein-based (biological) molecules with unique physical and biochemical properties. Our head-office is located in Hart bei Graz. In September 2021 bisy BIOS will move to its newly rented laboratory at ZWT (Zentrum für Wissens- und Technologietransfer in der Medizin, Neue Stiftingtalstraße 2 | 8010 Graz).

 

            

Claudia Rinnofner (CEO) 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.
