About (this "blog"? me?)

I am a mathematical modeller, that is, someone who uses mathematics to study real life problems. The problems I am interested in often concern biological systems and thus my brand of modelling is called mathematical biology (or biomathematics). To pigeonhole myself further, as a lot of my work is on the spread of infectious diseases, sometimes I call myself a mathematical epidemiologist.

I started my publication life mostly interested in quite theoretical problems in modelling, with little connection to reality. As part of my work in collaboration with Kamran Khan in what was then called the Bio.Diaspora Project and is now a company, Bluedot, I became more and more interested in the use of data. This has become a very important part of my scientific life and while I still enjoy tackling theoretical issues, I now often try to have a data connection.

In this blog, if one can call it so, I will share some encounters I have had with data, some datasets that I assembled in the process as well as, more generally, other stuff I have had to do as a mathematical modeller dealing with data. In some cases, this will concern manipulations I have had to carry out to produce a paper. In other cases, these are just random musings. I might even throw in the odd “lecture” about a modelling problem. Programming, when present, is in R.

Note that as an instructor, I believe in the value of low-level approaches. So when I can, I illustrate doing things in a relatively basic way, rather than right away using elaborate libraries.
