CSAW in a nutshell

What is the CSAW?

One week before the start of the semester on the Lausanne campus to understand the complexity of a specific sustainability issue, and co-create relevant student projects to address it, using innovative tools and methods.

The last edition has been co-created with a team of students: Lucie Castella (EL), Jean-André Davy-Guidicelli (SIE), Christophe Deloose (MT), Marguerite Fauroux (MT), Sarah Michel (SV), Victor Rey (SV), Loïc Wermeille (MT).

For and by whom?

For all bachelor and master students of EPFL and UNIL, with student coaches, members of the UNIL-EPFL community and guest speakers.

The CSAW is coordinated by Michka Mélo (VPA-DLL, main contact point for this initiative), Nicola Banwell (VPT), and Eric Domon (VPT). This initiative is supported by the Vice President for Responsible Transformation.

Why the CSAW?

There is a growing demand and need for future professionals to adapt their approaches, skills and tools to the complex societal issues they face and will face in the 21st century.

This week offers the opportunity to be trained with tools and methods allowing to act appropriately on these complex issues.
