Chartine was born in a refugee camp in Tanzania in 1995. Her family moved back to Rwanda when Chartine was four months old. She completed her secondary education at the Gashora Girls Academy of Science and Technology where she started a club called “Enliven,” that worked to tutor children from the Gashora village in English and writing skills. Chartine graduated from Bucknell University in 2018 with a degree in mechanical engineering. She has grown as a leader through her participation in social justice events and her experience as an engineering camp counselor. With her degree, she hopes to help build the infrastructure required to reduce Rwanda’s dependence on other nations for both construction and management. In 2016, Chartine spent her summer break participating in two programs at Bucknell: the Institute for Leadership in Sustainable Technology (ILST) program and the Institute for Leadership in Technology & Management (ILTM) program. Through these programs, she gained experience as a consultant, working with peers to develop a proposal for a solar panel project on a commercial building in ILST and to evaluate the feasibility of a marketing plan for a client's new line in ILTM. In the summer of 2017, Chartine was a mechanical engineering intern at Zipline International Inc., which manufactures and operates small drones that deliver life-saving medical products, such as blood, to patients in remote areas. Chartine designed and built machines that performed mechanical and performance tests.
