Community Involvement
Statement on Diversity and Inclusion
Throughout his research journey, Aristide has strived to ensure that the field of materials science can continue to be more diverse and inclusive. Thus far his approach has been to promote engagement in positive conversations, self education, and education of colleagues on historical origins of socio-economical disparities especially in America. OMSE Lab members are thus also encouraged to contribute, initiate, and engage in activities promoting equitable education.
Community Initiatives
Water2All Rwanda
As a native of Rwanda, Aristide spent several hours when he was younger walking to and from water wells and had to carry water home every day. Since it was a necessity, he never had to think twice on whether the time he spent on this inconvenient task could have been used for his education and career development. It was either thirst or reading time, the choice was obvious. To this day, many children still have to walk miles and spend hours to get water, and oftentimes, dirty water!
At the beginning of Covid 19, when access to clean water became more critical than ever before, Aristide initiated a project, Water2All, with the aim to find affordable ways to provide clean and running water in rural areas of Rwanda, starting with Kamonyi district. For more details on the project, feel free to reach out to Aristide. Thus far, he has raised enough funds through donations and personal efforts to build a water well that now provides clean water to over 50 households in Kamonyi!
BookSmart Rwanda
Aristide now aims to establish a platform for these children who no longer have to walk and wait in line for water to turn the water fetching times into reading and talent development times, an opportunity that he never had growing up. His ultimate goal is to establish youth centers, where children can gather to read, play, and be mentored. Currently, he is partnering with his parents, retired educators in Rwanda, to offer guidance and mentorship to children starting in Kamonyi district. His parents currently run a "Itetero" in their home, which is essentially a community daycare for local children. There, children can come and are taught basic reading and writing for free, and are also educated about hygiene practices and nutrition (examples of Itetero topics have been animated for online access, link). In partnership with the local institutions, the Itetero also serves as a spot for monitoring the health and growth of the children, especially those from low income families. Aristide aims to continue monitor the education progress of Itetero graduates and foster their career development through BookSmart Rwanda!
