ETHOS Technical Reports
Through community-engaged engineering experiences, the ETHOS Center — Engineers in Technical, Humanitarian Opportunities of Service Learning — connects students with communities in responsive, reciprocal partnerships to create technical solutions that advance social justice, human rights and sustainability for the common good. These experiential learning opportunities include immersions, breakouts, research and development projects and engineering design courses.
This collection includes research and technical reports and posters by ETHOS participants.
For more information, see the ETHOS Center website.
