Stine Krogh Steffensen

I have a PhD in natural product chemistry and the focus of my research is plant secondary metabolites* and their role in biological interactions in agriculture, environment and health. In my daily work I analyze these compounds using LCMSMS in both a simple targeted manner and in a semi-targeted manner utilizing techniques such as data dependent acquisition. I am dedicated to getting the most out of our QTrap instruments, exploiting the full potential of the triple quadrupole and linear iontrap. Furthermore, I have a special interest in chromatography, purification, method development and spectroscopy, and beside my experience in mass spectrometry, I have experience using various 1D and 2D NMR techniques for structure elucidation of plant secondary metabolites. I have a background in organic synthesis and I have found that knowledge of this combination of chemistry fields is advantageous for the diverse challenges that present themselves when working with natural products.

I obtained my PhD in natural products chemistry from the University of Copenhagen, Denmark in 2012, following a master and bachelor in organic chemistry from the same university. From 2013 I was employed at Aarhus University, Department of Agroecology, in a postdoc position in the RyeproC project, (www.ryeproc.dk) which focused on elucidating the reason behind the beneficial effect of a ryebread rich diet for prostate cancer patients. Recently I joined the Centre for Circular Bioeconomy (cbio.au.dk) to partake in the development of new, biobased industrial products from residual bio-mass from the agricultural sector.

 

* Secondary metabolites from plants play a diverse role in nature both in the plants themselves and in the world around. The pressure from factors such as climatic conditions, competing plants, herbivores, and microorganisms affect the content of secondary metabolites in a plant, and in turn, the ability to regulate secondary metabolite production affects the resilience of the plant. The resilience of a crop is a key factor in agriculture, but secondary metabolite content also impacts the consumers, as these biologically active compounds affect health in a range of ways. Some plants can be exploited industrially for their production of secondary metabolites as traditionally known for the perfume industry and the pharmaceutical industry, but the diverse nature of secondary metabolites holds possibilities for more bio-sustainable, industrial products that traditionally were petroleum-based.
