About

I work on the environmental impacts of digital technologies. At the intersection of interaction design and HCI, my work focuses on creating less consuming digital devices and services, and reducing dependency on digital technologies, while taking into account user experience.

In the past years, I studied smartphone obsolescence to understand the role of software in the renewal of smartphones, and the startegies used to extend their lifespan. I also studied attachments to smartphones, to understand why it is so hard to reduce smartphone usage and to not replace them when they become obsolete.

My work includes participative workshops, and creative media to share my findings.
