Key actors

“A strength of the program is that one can do interdisciplinary work ….

“Personally, this project is my first work experience. It helped me develop. And I also highlight the teamwork, since I’ve had to solve certain problems in the field, and I leaned on my colleagues, and they were always, wow! At least in this project that were super open. So I did feel support by a team. I think that was the first I learned: teamwork, empathy, assertiveness, experience.” (GFET3/ education sector focus group:10).

“We are extremely satisfied… as it advanced, it stayed flexible…and nobody knows how the pandemic is going to evolve… it could adapt even though the quarantines were coming.” (SH5,13)

“The fact that three universities have come together to carry out a project that benefits the community and economy in Antofagasta, in association with a company like BHP, that they’re concerned about the issue and provide us resources… I think that this private-public link is very positive, that it’s not so usual, that all those involved share a commitment and contribution to the public. That’s very important.” (SH/University decision-maker:3,5)
