Ever since the very beginning of my scientific work, I have been intrigued by mathematical techniques. As a very young scientist (Soetaert and Heip, 1990) I used monte carlo simulation to show that diversity estimates should be used with caution due to their dependence on sample size. Much later I worked on mathematical methods to sample underdetermined linear systems (van den Meersche et al., 2009), or investigated the usability of data assimilation techniques in aquatic systems (Soetaert and Gregoire, 2011). The most extreme example of my work in the field of mathematics, however, is my last book (Soetaert et al., 2012). This deals with both the theory of numerically solving differential equations and their implementation in the software R. I wrote the R example chapters, but also two theoretical chapters – I leave it to the reader to guess which.
