About us

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.

Alexander Gutmann, DI Dr. has 14 years of experience in biotechnology research and development. He worked for five years in the CDMO industry at Lonza and Arxada. Alexander managed development and optimization of fermentation and downstream processes and organized scale-up to piloting and commercial manufacturing. He has also a strong academic track record in biocatalysis and related fields. He co-authored more than 20 peer reviewed publications..

Alexandra Deibuk, M.Sc. has a bachelor’s degree in Molecular Biology and a master’s degree in Biochemistry and Molecular Biomedicine. She did her masters thesis at Graz University of Technology in collaboration with myBIOS. She is currently working as Lab-Team Leader at myBIOS.

Sandra Flecker, M.Sc. studied Molecular Biology, Biochemistry and Molecular Biomedicine at University of Graz. She joined myBIOS in 2021. Prior to it she was working in a diagnostics company. She is an experienced scientist, specialized in the field of Pichia pastoris.

Lukas Schönleitner pursued Molecular Biology during his undergraduate studies. He is currently in the final stages of completing his master’s thesis in Biotechnology while also holding a part-time position at myBIOS.
