Hanna Eriksson Röhnisch

In my current position as a researcher at the Department of Molecular Sciences, the research focus is on a combination of metabolomics and food science. I participate in various projects in close collaboration with other researchers, doctoral students and master students, and my work takes place via two research groups, Organic chemistry and Structure and properties of food, respectively. I also perform teaching in chemistry, mainly  as a supervisor on computer- and/or laboratory exercises. I have previously done a postdoctoral fellowship in organic chemistry at SLU and I defended my PhD thesis entitled "Automated quantification of plasma metabolites by NMR to study prostate cancer risk biomarkers" at the same university in 2019.

Metabolomics: In metabolomics, various techniques (e.g., NMR spectroscopy) are used for the analysis of low molecular weight compounds (metabolites) in many samples from biological samples. Metabolite concentrations are regulated by complex gene-environmental factors and therefore metabolomics has many different areas of application. A prerequisite for large-scale metabolomics studies is  efficient methods for data analysis. Design, implementation and testing of automated methods is therefore important.  Method development for effective data analysis can allow quantifications in more complex samples.

Food science: Development of new plant-based foods can contribute to a more sustainable food production- and consumption, but sometimes plant-based dairy substitutes display comparatively poor nutritional and/or sensory properties. In the FORMAS-funded project "Fermentation of Swedish faba beans for foods with improved texture, flavour and nutritional properties", we work with Swedish faba bean legume as raw material and evaluate different workflows for the production of yogurt-like food prototypes with the aim of improving nutritional and sensory properties.
