The images captured by large telescopes, the sound of a voice or the images of oceans obtained by satellites are all complex natural signals that are very difficult to understand.

Where does a bottle go when you throw it in the ocean?

However, despite being very different from each other they have similarities in their organisation and if we could observe these very precisely, we would see that these signals contain characteristics that explain their behaviour on a large scale.

Based on these observations, Hussein Yahia uses satellite images of the ocean to attempt to predict the dynamics of marine currents in high resolution and therefore changes in a phenomenon on the surface of the ocean that is dependent on these same currents (an oil slick for example). He will soon be carrying out similar work on other signals, such as cardiac signals, which will allow doctors to predict cardiac arrest phenomena before they even occur.
