My research group is interested in combining mathematical, statistical, and experimental approaches to learn about the biological world, and how we can interact with it to improve human lives. 

You can read more at the research group website.

I'm also involved in teaching, mainly statistical, mathematical modelling, and computational biology approaches at UiB.
