Biography

Born and brought up in Denmark, I did my undergraduate degree in Agriculture at the Royal Veterinary and Agricultural University, in Copenhagen. This was supplemented with an ERASMUS exchange year at The University of Aberdeen.

I studied for my MSc and PhD in Plant Biochemistry at the same institution. During my PhD I investigated the regulation of primary carbon metabolism in plants focusing on the model plant Arabidopsis thaliana, using biochemical and molecular biological methods. Following my PhD, I obtained funding from the Danish Research Council to carry out a post-doctoral research project studying the role of carbohydrates as regulators of gene-expression in A. thaliana. This work was carried out at The University of Edinburgh, using recombinant plants and bio-imaging methods. In a second post-doc in Edinburgh I focused on starch metabolism in A. thaliana.

Since joining the University of Cumbria I have been teaching modules in  Biodiversity , contributed to several genetics based modules and delivered sessions in Animal Biology and Forest Health and Protection. 

I am the module leader for: 

Biodiversity 1 

Biodiversity 2 

Conservation Genetics
