Picture of my research group, during a trip to Germany last summer.
Are you wondering what I am doing during the days, when I am at work? The basic principle behind my work is described in a very simple cartoon-like fashion on this link. It describes the principle of hypothesis testing, which I am doing not by looking and thinking (as most biologists still are doing) but by simulating mathematical models on a computer. In my case, the different theories are different ideas of how a specific biological system works (in the cartoon this corresponds to what is the best geometrical shape), and in my case the data are experimental data from this system, usually time-series of concentrations in response to different stimulations (in the cartoon this corresponds to the dots).
(a more technical description is found e.g. in the following method review, and in this application review, and in this earlier blog, and in the news)
