Photos of nature

This summer I spent almost two months in a cottage in the Swedish countryside with my family. The cottage is fairly isolated with the closest neighbours a kilometer or so away. This meant living closer to nature than I have ever done, and resulted in me taking an interest in the flora and fauna of the surrounding meadow and forest. The below photos document some of my findings. I will in future post (with the tentative title 'The doubts of a mathematical biologist') write more about my impressions of living close to nature.

The evolution of carrying capacity in constrained and expanding tumour cell populations

My position at Moffitt Cancer Center certainly payed off in terms of research output. Recently my second paper based on work done at the Integrated Mathematical Oncology group was published. The paper investigates the dynamics of carrying capacity evolution in tumours and was written together with Sandy Anderson. The paper is published in Physical Biology, and was chosen as a "featured article" and is therefore open access for a limited time.

A copy can be found here, and the arxiv-version here (which will remain open access forever).
