In April 2021, along with several other female students from the Faculty of Science and Technology of the Marien Ngouabi University, she responded to the call for applications for the "Women and Science" grants from the Congolese Foundation for Medical Research. She was one of the two laureates for the Master 2 level. Determined to be a true Woman of Science, Sarah Colombe applied a few weeks later for a PhD scholarship from the University of Tübingen in the framework of capacity building in the South. Her application was positively evaluated.
As part of her PhD thesis at the Institute of Tropical Medicine of the University of Tübingen in Germany, Sarah Colombe will work on the molecular epidemiology of tropical diseases.
