Postdoctoral Researcher (100%)

The Food Innovation and Process Design group at HES-SO Valais led by Prof. Mishra and the Food Structure Engineering group at ETH Zürich led by Prof. Rühs are jointly advancing how non-alcoholic beer and wine can be made without dealcoholisation using non-Saccharomyces yeast. The successful candidate will join an interdisciplinary research team developing novel fermentation technologies for the sustainable production of non-alcoholic beer and wine. The project combines yeast biotechnology and biochemistry, bioprocess development, and industrial scale-up to translate laboratory innovations into industrial practice.

Your mission

• Conduct applied research on the metabolism and physiology of non-Saccharomyces yeasts in beer and wine, with particular emphasis on respiratory metabolism and non-alcoholic fermentations.

• Investigate the biochemistry of respiratory metabolism in yeasts and its influence on wine and beer organoleptic quality.

• Develop, optimise and scale biotechnological fermentation processes from laboratory to pilot and industrial scale.

• Collaborate with industrial partners from the brewing, wine and biotechnology sectors to translate research into industrial applications.

Your profile

• PhD in (Food)-Biotechnology, Bioprocess Engineering, or on the production of non-alcoholic wine and beer with a focus on non-Saccharomyces yeast.

• Experience in aerobic and anaerobic fermentation, bioprocess development, process scale-up and fermentation engineering.

• You combine a scientific track record with an entrepreneurial mindset, and you can easily translate science into application.

• You can operate bioreactors from the 1L to the 1000L scale and can translate the biochemistry of a single cell to industrial fermentation.

• Fluent in English, B2 in either French or German.
