R Shiny and how it turns scientists into web designers

I started to use ‘R’ around eight years ago, when graduating from university. This open-source programming language with a focus on statistics can be used -in the most simple case- to generate plots and visualizations that are more appealing than conventional ‘spreadsheet’ editors.

Risk and Return: The economics of a photosynthetic cell

Today me and my co-authors published a paper in Cell Reports that is the result of a roughly two-year adventure into the economics of cyanobacteria.

This Göteborg landmark, the Gothia towers, features a pool attached to the building’s facade.

When you live in Stockholm and tell your friends or colleagues that you want to visit  the second-largest city in Sweden, it can happen that they raise an eyebrow and ask if you have some tiresome business there, or why else would anybody go to Göteborg? Continue reading Väst Kust Customs
