Brigitte GASSER is leading the team on "Molecular biotechnology of yeasts" at the Department of Biotechnology. Her research aims at the molecular characterization and physiology of yeasts such as Pichia pastoris under recombinant protein production conditions, with special emphasis on oxidative protein folding, organelle-specific redox regulation connected to protein folding and secretion, and secretion related stresses (e.g. unfolded protein response, ROS formation, redox balancing). Thereby, one goal is to understand the regulation of the secretory pathway. Furthermore, she is interested in novel ways of strain engineering for improved protein secretion or the identification of novel cellular tools based on systems biology approaches such as genomics, transcriptomics, proteomics and metabolomics.

Reingard GRABHERR is Associate Professor at the Department of Biotechnology. Her main focus is directed towards protein expression design, cellular engineering and systems biology approaches for the production of functional proteins, virus like particles and infectious viruses. Her goals are influenza virus vaccine design in insect cells and mammalian cells as well as improving cell factories in general for production of functional proteins (e.g. enzymes) and DNA (DNA vaccine). Her core competence is design of expression cassettes and genetic engineering of production strains, needed for pharmaceutical and industrial biotechnology. Her special interest lies in improving surface display techniques in insect and mammalian cells using recombinant baculoviruses, exploring different strategies for display of functional proteins, expression of eukaryotic complex and multimeric proteins in insect cells, comparing the insect cell and yeast system in terms of display efficiency and authenticity of eukaryotic proteins and the development of cloning strategies for large and diverse protein libraries in insect and mammalian cells.

Stefan HOFBAUER is part of the Institute of Biochemistry in the Protein Biochemistry group of at the Department of Chemistry at BOKU Vienna. His current research focus is on the elucidation of the prokaryotic heme biosynthesis pathway. Many enzymes are involved in the so-called "coproporphyrin-dependent" heme biosynthesis pathway, which is mainly utilized by Gram-positive bacteria, many of which are pathogens. A profound understanding of the structure function relationship of each individual enzyme, involved in this pathway, is essential for potential future bio-medical applications (e.g. discovery for new classes of antibiotics). Further research interests are biochemical and biophysical studies of heme enzymes in general (e.g. peroxidases, chlorite dismutases,…) to unravel the reaction mechanisms of highly interesting reactions.
