Dear all, this is the first announcement for the summer school on *Mathematical Modelling in Life Sciences*, to be held at the Centro di Ricerca Matematica "E. De Giorgi" in Pisa, Italy, from September 13th to September 15th, 2017. The aim of the school is to introduce and discuss some recent developments in analytical and probabilistic modelling for life sciences. The school will feature two main courses, by *Benoit Perthame* (Université Pierre et Marie Curie in Paris) and *Sylvie Méléard* (Ecole Polytechnique Université Paris- Saclay), as well as additional lectures by *François Delarue* (Université de Nice). There will also be a limited number of short contributed talks by some of the participants. This summer school is intended for PhD students and young researchers, but open for everyone. Registration to the school is free, but compulsory for organisatorial purposes. Some funds are available to offer financial support to a limited number of selected students and young researchers (post-docs). The deadline for application is 29th June 2017.This school would not have been possible, without the support by Centro di Ricerca Matematica "E. De Giorgi", Università di Pisa and GNAMPA-INdAM. More information and the registration form are available on the website http://www.crm.sns.it/event/409/ We are looking forward to seeing you in Pisa. The organisers, Lisa Beck, Luigi Amedeo Bianchi, Dirk Blömker, Franco Flandoli, Marco Romito, Dario Trevisan
